技术领域Technical field
本申请属于通信技术领域，尤其涉及天线功率调节方法、终端设备及计算机可读存储介质。This application belongs to the field of communication technology, and in particular relates to an antenna power adjustment method, terminal equipment, and computer-readable storage medium.
背景技术Background technique
比吸收率或电磁波吸收比值(specific absorption rate，SAR)是指单位时间内，单位质量的人体所吸收或消耗的电磁辐射能量，用于衡量电磁辐射对人体的影响，其中，SAR越大，表示对人体的影响越大。为降低电磁辐射对人体的影响，当用户靠近终端设备时，一般会降低终端设备中天线的发射功率，以降低SAR。The specific absorption rate or electromagnetic wave absorption rate (SAR) refers to the electromagnetic radiation energy absorbed or consumed by a unit mass of the human body per unit time, and is used to measure the impact of electromagnetic radiation on the human body. The greater the SAR, the The greater the impact on the human body. In order to reduce the influence of electromagnetic radiation on the human body, when the user approaches the terminal device, the transmitting power of the antenna in the terminal device is generally reduced to reduce the SAR.
现有技术中，一般通过终端设备中的接近式电容传感器或接近式光学传感器来判断人体是否靠近终端设备，当人体靠近终端设备时，基于统一标准降低终端设备中所有天线的发射功率。但终端设备中不同位置的天线与人体之间的距离不相同，因此，所产生的SAR也并不相同，无差别地对所有天线进行统一的功率降低，会导致终端设备的通信性能下降，影响用户的通讯体验。In the prior art, the proximity capacitive sensor or proximity optical sensor in the terminal device is generally used to determine whether the human body is close to the terminal device. When the human body approaches the terminal device, the transmission power of all antennas in the terminal device is reduced based on a unified standard. However, the distance between the antennas in different positions of the terminal equipment and the human body is not the same, therefore, the SAR generated is also not the same. The uniform power reduction of all antennas indiscriminately will cause the communication performance of the terminal equipment to decrease and affect The user’s communication experience.

应理解，当终端设备处于手持读屏状态时，用户的手部会对屏幕中的部分区域进行遮挡，从而使得屏幕内部分光源发射的光线经手部遮挡后反射至屏幕内的光线传感器。因此，可以根据光线传感器获取的光线信息来确定屏幕中的遮挡区域，以确定终端设备是否处于手持读屏状态。It should be understood that when the terminal device is in a handheld screen reading state, the user's hand will block a part of the screen, so that the light emitted by a part of the light source in the screen is blocked by the hand and reflected to the light sensor in the screen. Therefore, the occlusion area in the screen can be determined according to the light information obtained by the light sensor to determine whether the terminal device is in a handheld screen reading state.
具体地，可以识别第一图像中的第一目标特征和第二图像中的第二目标特征。当第一目标特征为头部特征，且第一目标特征对应的头部与终端设备之间的第一距离小于第一距离阈值时，确定预定目标包括头部。当第一目标特征为脸部特征时，可以根据屏幕中的光线信息获取屏幕中的遮挡区域，并确定遮挡区域的区域面积和区域位置。若区域面积小于第二面积阈值，且区域位置分布满足第一预设条件，则确定预设目标包括手部。若区域面积大于或等于第二面积阈值，或区域位置分布不满足第一预设条件，且第二目标特征为身体特征，则确定预定目标包括身体。当第一目标特征为环境特征，第二目标特征为身体特征，且第二目标特征对应的身体与终端设备之间的第一距离小于第一距离阈值时，或者当第一目标特征为身体特征，且第一目标特征对应的身体与终端设备之间的第一距离小于第一距离阈值时，则确定预定目标包括身体。当第一目标特征和第二目标特征均为环境特征时，则确定预定目标包括手部。Specifically, the first target feature in the first image and the second target feature in the second image can be identified. When the first target feature is a head feature, and the first distance between the head corresponding to the first target feature and the terminal device is less than the first distance threshold, it is determined that the predetermined target includes a head. When the first target feature is a facial feature, the occlusion area in the screen can be obtained according to the light information on the screen, and the area area and the location of the occlusion area can be determined.

在该实现方式中，可以获取摄像头采集的图像和终端设备中各天线的阻抗变化值，并可以根据图像和阻抗变化值来进行预定目标的确定，以提高预定目标确定的准确性。In this implementation manner, the image collected by the camera and the impedance change value of each antenna in the terminal device can be obtained, and the predetermined target can be determined according to the image and the impedance change value, so as to improve the accuracy of the predetermined target determination.
应理解，当终端设备处于手持读屏状态时，用户的手部一般会接触终端设备的部分区域，从而使得该部分区域对应的天线的阻抗会发生较大变化。因此，终端设备可以根据各天线的阻抗变化值来确定手部持握终端设备的区域，以确定终端设备是否处于手持读屏状态。It should be understood that when the terminal device is in a handheld screen-reading state, the user's hand generally touches a part of the terminal device, so that the impedance of the antenna corresponding to this part of the area will change greatly. Therefore, the terminal device can determine the area where the hand holds the terminal device according to the impedance change value of each antenna, so as to determine whether the terminal device is in a handheld screen reading state.
具体地，可以识别第一图像中的第一目标特征和第二图像中的第二目标特征。当第一目标特征为头部特征，且第一目标特征对应的头部与所述终端设备之间的第一距离小于第一距离阈值时，确定预定目标包括头部。当第一目标特征为脸部特征时，根据终端设备中各天线的阻抗变化值确定目标天线，目标天线为阻抗变化值大于预设变化阈值的天线。若目标天线的位置分布满足第二预设条件，则确定预设目标包括手部。若目标天线的位置分布不满足第二预设条件，且第二目标特征为身体特征，则确定预定目标包括身体。当第一目标特征为环境特征，第二目标特征为身体特征，且第二目标特征对应的身体与终端设备之间的第一距离小于第一距离阈值时，或者当第一目标特征为身体特征，且第一目标特征对应的身体与终端设备之间的第一距离小于第一距离阈值时，则确定预定目标包括身体。当第一目标特征和第二目标特征均为环境特征时，则确定预定目标包括手部。Specifically, the first target feature in the first image and the second target feature in the second image can be identified. When the first target feature is a head feature, and the first distance between the head corresponding to the first target feature and the terminal device is less than the first distance threshold, it is determined that the predetermined target includes a head.

If the position distribution of the target antenna satisfies the second preset condition, it is determined that the preset target includes a hand. If the location distribution of the target antenna does not satisfy the second preset condition, and the second target feature is a physical feature, it is determined that the predetermined target includes a body. When the first target feature is an environmental feature, the second target feature is a physical feature, and the first distance between the body corresponding to the second target feature and the terminal device is less than the first distance threshold, or when the first target feature is a physical feature , And when the first distance between the body corresponding to the first target feature and the terminal device is less than the first distance threshold, it is determined that the predetermined target includes a body. When the first target feature and the second target feature are both environmental features, it is determined that the predetermined target includes a hand.
在一个示例中，本申请实施例也可以基于图像和电容变化/电阻变化来确定预定目标。示例性的，当第一目标特征为脸部特征时，终端设备可以获取屏幕中的电容变化/电阻变化的变化区域，并可以确定变化区域的区域位置。在区域位置分布满足第三预设条件时，可以确定预设目标包括手部。其中，第三预设条件可以与第一预设条件相同，即第三预设条件可以为手部持握终端设备时手指、手掌等部位触摸屏幕的位置分布。In an example, the embodiment of the present application may also determine the predetermined target based on the image and the capacitance change/resistance change. Exemplarily, when the first target feature is a facial feature, the terminal device can acquire the change area of the capacitance change/resistance change on the screen, and can determine the location of the change area. When the regional location distribution satisfies the third preset condition, it may be determined that the preset target includes a hand. The third preset condition may be the same as the first preset condition, that is, the third preset condition may be the position distribution of the fingers, palms and other parts of the touch screen when the terminal device is held by the hand.
在一个示例中，本申请实施例也可以结合屏幕中的光线信息、各天线的阻抗变化值和图像来确定预定目标。示例性的，在第一目标特征为脸部特征时，终端设备可以根据屏幕中的光线信息获取屏幕中的遮挡区域，并可以确定遮挡区域的区域面积和区域位置，同时可以根据终端设备中各天线的阻抗变化值确定目标天线,当区域面积小于第二面积阈值，且区域位置分布满足第一预设条件，同时目标天线的位置分布满足第二预设条件时，确定预设目标包括手部。In an example, the embodiment of the present application may also combine the light information on the screen, the impedance change value of each antenna, and the image to determine the predetermined target. Exemplarily, when the first target feature is a facial feature, the terminal device can obtain the occlusion area in the screen according to the light information on the screen, and can determine the area and location of the occlusion area. The impedance change value of the antenna determines the target antenna. When the area area is less than the second area threshold, and the area location distribution meets the first preset condition, and the target antenna location distribution meets the second preset condition, it is determined that the preset target includes the hand .
示例性的，所述确定与所述预定目标对应的待调节天线可以包括：Exemplarily, the determining the antenna to be adjusted corresponding to the predetermined target may include:
根据屏幕中的光线信息获取所述屏幕中的遮挡区域，并确定所述遮挡区域的区域面积和区域位置；Acquiring the shielding area in the screen according to the light information in the screen, and determining the area and location of the shielding area;
根据所述区域面积和所述区域位置确定与所述预定目标对应的待调节天线。The antenna to be adjusted corresponding to the predetermined target is determined according to the area of the area and the location of the area.
需要说明的是，当预定目标包括头部时，即当终端设备靠近头部使用时，头部会对屏幕内的部分光源发射的光线进行遮挡，遮挡后的光线则可反射至屏幕内。同样地，当预定目标包括手部时，即当用户手持终端设备时，用户的手部也会对屏幕中的部分区域进行遮挡，从而使得屏幕内的部分光源发射的光线经手部遮挡后反射至屏幕内。因此，在确定预定目标包括头部和/或手部后，终端设备可以根据屏幕中的光线信息来确定与预定目标对应的待调节天线。It should be noted that when the predetermined target includes the head, that is, when the terminal device is used close to the head, the head will block part of the light emitted by the light source in the screen, and the blocked light can be reflected into the screen. Similarly, when the predetermined target includes the hand, that is, when the user holds the terminal device, the user's hand will also block a part of the screen, so that the light emitted by part of the light source in the screen is blocked by the hand and reflected to Inside the screen. Therefore, after determining that the predetermined target includes the head and/or the hand, the terminal device can determine the antenna to be adjusted corresponding to the predetermined target according to the light information on the screen.
具体地，当所述预定目标为头部时，所述根据所述区域面积和所述区域位置确定与所述预定目标对应的待调节天线可以包括：Specifically, when the predetermined target is a head, the determining the antenna to be adjusted corresponding to the predetermined target according to the area area and the position of the area may include:
根据所述区域面积和所述区域位置获取第一目标遮挡区域，并将所述第一目标遮挡区域对应的第一目标天线确定为与所述头部对应的待调节天线，所述第一目标遮挡区域为区域面积大于第一面 积阈值，且区域位置为预设位置的遮挡区域。Obtain a first target occlusion area according to the area area and the location of the area, and determine the first target antenna corresponding to the first target occlusion area as the antenna to be adjusted corresponding to the head, and the first target The shielded area is a shielded area whose area is greater than the first area threshold and the location of the area is a preset position.
其中，第一面积阈值可通过对用户将终端设备靠近头部使用时，头部与终端设备贴近的区域面积进行分析确定。因在贴头通话时，头部一般是贴近终端设备的上侧，因此，预设位置可设置为屏幕中靠近终端设备上边缘或者靠近前置摄像头的位置。Wherein, the first area threshold may be determined by analyzing the area of the area where the head and the terminal device are close when the user uses the terminal device close to the head. Since the head is generally close to the upper side of the terminal device during a head-to-head call, the preset position can be set to a position close to the upper edge of the terminal device or close to the front camera on the screen.
具体地，当所述预定目标为手部时，所述根据所述区域面积和所述区域位置确定与所述预定目标对应的待调节天线可以包括：Specifically, when the predetermined target is a hand, the determining the antenna to be adjusted corresponding to the predetermined target according to the area area and the position of the area may include:
根据所述区域面积和所述区域位置确定第二目标遮挡区域，并将所述第二目标遮挡区域对应的第二目标天线确定为与所述手部对应的待调节天线，所述第二目标遮挡区域为区域面积小于第二面积阈值，且区域位置分布满足预设条件的遮挡区域。The second target shielding area is determined according to the area area and the position of the area, and the second target antenna corresponding to the second target shielding area is determined as the antenna to be adjusted corresponding to the hand, and the second target The shielded area is a shielded area where the area of the area is smaller than the second area threshold, and the area location distribution meets the preset condition.
其中，第二面积阈值可以通过对用户手持终端设备时，用户手部与屏幕所形成的接触面积或遮挡面积进行分析确定，第二面积阈值小于头部中的第一面积阈值。预设条件可以为手部持握终端设备时手指、手掌等部位在屏幕中的位置分布，例如可以为屏幕左侧边、右侧边和/或屏幕中间具有的单点或多点的位置分布等。Wherein, the second area threshold may be determined by analyzing the contact area or occlusion area formed by the user's hand and the screen when the user holds the terminal device, and the second area threshold is smaller than the first area threshold in the head. The preset condition can be the position distribution of fingers, palms and other parts on the screen when the terminal device is held by the hand. For example, it can be the position distribution of a single point or multiple points on the left side, right side of the screen, and/or in the middle of the screen. Wait.
示例性的，所述确定与所述预定目标对应的待调节天线可以包括：Exemplarily, the determining the antenna to be adjusted corresponding to the predetermined target may include:
根据所述终端设备中各天线的阻抗变化值确定第三目标天线，并获取所述第三目标天线的位置信息，所述第三目标天线为阻抗变化值大于预设变化阈值的天线；Determine a third target antenna according to the impedance change value of each antenna in the terminal device, and obtain position information of the third target antenna, where the third target antenna is an antenna with an impedance change value greater than a preset change threshold;
根据所述第三目标天线的位置信息确定与所述预定目标对应的待调节天线。The antenna to be adjusted corresponding to the predetermined target is determined according to the position information of the third target antenna.
需要说明的是，当有目标紧贴终端设备中的某一天线时，该天线的阻抗会发生较大变化。而在预定目标包括头部时，即在终端设备靠近头部使用时，头部一般会紧贴终端设备的上侧，使得头部所贴近的天线的阻抗会发生较大变化。同样地，在用户手持终端设备时，若手部持握的位置中包括天线，则该天线的阻抗也会发生较大变化。因此，在确定预定目标包括头部和/或手部时，终端设备还可以根据各天线的阻抗变化值来确定与预定目标对应的待调节天线。It should be noted that when a target is close to a certain antenna in the terminal device, the impedance of the antenna will change greatly. When the predetermined target includes the head, that is, when the terminal device is used close to the head, the head generally closes to the upper side of the terminal device, so that the impedance of the antenna close to the head changes greatly. Similarly, when the user holds the terminal device, if the position where the hand holds the antenna includes an antenna, the impedance of the antenna will also change significantly. Therefore, when it is determined that the predetermined target includes the head and/or the hand, the terminal device may also determine the antenna to be adjusted corresponding to the predetermined target according to the impedance change value of each antenna.
示例性的，在预定目标包括头部和/或手部时，终端设备也可以结合屏幕中的光线信息和天线的阻抗变化值来确定与预定目标对应的待调节天线。例如，在预定目标包括头部时，可以先根据屏幕中的光线信息和各天线的阻抗变化值分别确定出第一目标天线和第三目标天线，然后可以将第一目标天线和第三目标天线统一确定为与头部对应的待调节天线；或者可以将第一目标天线和第三目标天线中所重叠的天线确定为与头部对应的待调节天线。在预定目标包括头部时，也可以先根据屏幕中的光线信息确定第一目标遮挡区域，然后可以获取第一目标遮挡区域对应的第一目标天线的阻抗变化值，并可以将阻抗变化值大于预设变化阈值的第一目标天线确定为头部对应的待调节天线。Exemplarily, when the predetermined target includes the head and/or the hand, the terminal device may also combine the light information on the screen and the impedance change value of the antenna to determine the antenna to be adjusted corresponding to the predetermined target. For example, when the predetermined target includes the head, the first target antenna and the third target antenna can be determined according to the light information on the screen and the impedance change value of each antenna, and then the first target antenna and the third target antenna can be combined. Unifiedly determine the antenna to be adjusted corresponding to the head; or the overlapping antenna of the first target antenna and the third target antenna may be determined as the antenna to be adjusted corresponding to the head. When the predetermined target includes the head, the first target occlusion area can also be determined according to the light information on the screen, and then the impedance change value of the first target antenna corresponding to the first target occlusion area can be obtained, and the impedance change value can be greater than The first target antenna with the preset change threshold is determined as the antenna to be adjusted corresponding to the head.
应理解，当终端设备靠近头部时，还可以同时存在靠近手部的情况。因此，在根据第一图像确定预定目标包括头部时，可以在根据屏幕中的光线信息和/或天线的阻抗变化值确定头部与终端设备所靠近的区域时，根据屏幕中的光线信息和/或天线的阻抗变化值确定是否存在手部持握终端设备的情况，以及当存在手部持握终端设备的情况时，确定手部在终端设备中所持握的区域。因此，在预定目标包括头部和手部时,可以根据头部与终端设备靠近的区域确定与头部对应的第一待调节天线以及根据手部在终端设备中所持握的区域确定与手部对应的第二待调节天线，并可以根据头部SAR对第一待调节天线进行发射功率的调节，以使得靠近头部的第一待调节天线满足头部SAR指标，同时可以根据四肢SAR对第二待调节天线进行发射功率的调节，以使得靠近手部的第二待调节天线满足四肢SAR指标。It should be understood that when the terminal device is close to the head, it may also be close to the hand at the same time. Therefore, when it is determined that the predetermined target includes the head according to the first image, the area between the head and the terminal device can be determined according to the light information on the screen and/or the impedance change value of the antenna. /Or the impedance change value of the antenna determines whether there is a situation where the hand is holding the terminal device, and when there is a situation where the hand is holding the terminal device, the area where the hand is held in the terminal device is determined. Therefore, when the predetermined target includes the head and the hand, the first antenna to be adjusted corresponding to the head can be determined according to the area close to the head and the terminal device, and the first antenna to be adjusted can be determined according to the area held by the hand in the terminal device. The corresponding second antenna to be adjusted can adjust the transmit power of the first antenna to be adjusted according to the SAR of the head, so that the first antenna to be adjusted close to the head meets the head SAR index, and at the same time, the first antenna to be adjusted can be adjusted according to the SAR of the extremities. The second antenna to be adjusted adjusts the transmission power, so that the second antenna to be adjusted close to the hand meets the SAR index of the limbs.
示例性的，当终端设备的屏幕为电容屏或电阻屏时，若有目标与屏幕中的某一区域接触，该区 域即会产生电容变化或产生电阻变化。而在预定目标包括头部或手部时，即在终端设备靠近头部或靠近手部使用时，头部或手部一般会与屏幕中的部分区域接触，从而使得该区域产生电容变化或产生电阻变化。因此，终端设备还可以根据屏幕的电容变化以及变化区域或屏幕的电阻变化以及变化区域来确定与头部或与手部对应的待调节天线。Exemplarily, when the screen of the terminal device is a capacitive screen or a resistive screen, if a target contacts a certain area of the screen, the area will have a capacitance change or a resistance change. When the predetermined target includes the head or the hand, that is, when the terminal device is used close to the head or close to the hand, the head or the hand will generally contact a part of the screen area, which causes the capacitance change or generation of this area. Resistance changes. Therefore, the terminal device can also determine the antenna to be adjusted corresponding to the head or the hand according to the capacitance change and the change area of the screen or the resistance change and the change area of the screen.

应理解，在对待调节天线的发射功率进行降低之后,为进一步降低天线产生的电磁辐射对用户的影响，可以获取终端设备中各天线与预定目标之间的第二距离，并可以根据第二距离对终端设备的发射天线进行切换，以将终端设备的发射天线切换至距离预定目标较远的天线。例如，在头部靠近终端设备时，可以将发射天线由位于终端设备上侧靠近头部的天线切换至终端设备下侧远离头部的天线，或者切换至终端设备背部的天线。在手部持握终端设备时，可以将发射天线由被手部持握的天线切换至没有被手部持握的天线。It should be understood that after the transmit power of the antenna to be adjusted is reduced, in order to further reduce the influence of the electromagnetic radiation generated by the antenna on the user, the second distance between each antenna in the terminal device and the predetermined target can be obtained, and the second distance can be obtained according to the second distance. Switch the transmitting antenna of the terminal device to switch the transmitting antenna of the terminal device to an antenna farther from the predetermined target. For example, when the head is close to the terminal device, the transmitting antenna can be switched from the antenna on the upper side of the terminal device close to the head to the antenna on the lower side of the terminal device away from the head, or switch to the antenna on the back of the terminal device. When the terminal device is held by the hand, the transmitting antenna can be switched from the antenna held by the hand to the antenna not held by the hand.

如图1所示，终端设备为满足不同频段/制式的无线通信标准需求，一般会在机身的多个位置设置不同的天线101。在终端设备的使用过程中，这些天线会产生电磁辐射，而当人体距离终端设备较近时，所产生的电磁辐射会影响人体健康。因此，在终端设备的使用过程中，当人体靠近终端设备时，一般会降低终端设备中天线的发射功率，从而降低SAR，以满足SAR指标，减少电磁辐射对人体健康的影响。As shown in FIG. 1, in order to meet the wireless communication standard requirements of different frequency bands/standards, the terminal device generally installs different antennas 101 at multiple positions of the fuselage. During the use of terminal equipment, these antennas will generate electromagnetic radiation, and when the human body is close to the terminal equipment, the generated electromagnetic radiation will affect human health. Therefore, during the use of terminal equipment, when the human body approaches the terminal equipment, the transmitting power of the antenna in the terminal equipment is generally reduced, thereby reducing the SAR to meet the SAR index and reducing the impact of electromagnetic radiation on human health.
现有技术中，一般通过终端设备中的接近式电容传感器或接近式光学传感器来判断人体是否靠近终端设备，当人体靠近终端设备时，则基于统一标准(即统一的SAR指标)降低终端设备中所有天线的发射功率。但终端设备中不同位置的天线与人体之间的距离不相同，即不同位置的天线所产生的SAR并不相同，例如，在终端设备贴近头部使用(如使用听筒通话)时，终端设备顶部的天线靠近头部，对头部所产生的SAR一般较大，而终端设备底部的天线远离头部，对头部所产生的SAR较小，无差别地对顶部天线和底部天线的发射功率进行统一的降低，会导致终端设备的通信性能下降，影响用户的通讯体验。In the prior art, the proximity capacitive sensor or proximity optical sensor in the terminal device is generally used to determine whether the human body is close to the terminal device. Transmit power of all antennas. However, the distance between the antennas in different positions in the terminal equipment and the human body is not the same, that is, the SAR generated by the antennas in different positions is not the same. The antenna is close to the head, and the SAR generated to the head is generally large, while the antenna at the bottom of the terminal device is far away from the head, and the SAR generated to the head is small. The uniform reduction will cause the communication performance of the terminal equipment to decline, and affect the user's communication experience.
另外，目前针对靠近终端设备的人体部位的不同，对终端设备所产生的SAR也具有不同的SAR指标，例如，可以具有头部靠近终端设备时的头部SAR指标、人体躯干靠近终端设备时的身体SAR指标以及四肢靠近终端设备(如手持终端设备)时的四肢SAR指标，头部SAR指标、身体SAR指标和四肢SAR指标并不相同，其中，四肢SAR指标可高于头部SAR指标和身体SAR指标。现有技术中，在人体靠近终端设备时，基于统一指标降低所有天线的发射功率，会使得终端设备无法满足对应的SAR指标，例如在无论是头部、身体还是手部靠近终端设备时，都基于四肢SAR指标来统一降低所有天线的发射功率，会使得在头部靠近终端设备时，终端设备无法满足头部SAR指标；或者使得终端设备中天线的发射功率降低过多，导致终端设备的通信性能下降，影响用户的通讯体验，例如在无论是头部、身体还是手部靠近终端设备时，都基于头部SAR指标来统一降低所有天线的发射功率，会使得在手部靠近终端设备时，天线的发射功率降低过多，导致终端设备的通信性能下降，从而容易出现掉网、掉话等问题。In addition, at present, the SAR generated by the terminal device also has different SAR indicators for the different parts of the human body close to the terminal device. Body SAR indicators and limb SAR indicators when the limbs are close to terminal devices (such as handheld terminal devices). Head SAR indicators, body SAR indicators, and limb SAR indicators are different. Among them, limb SAR indicators can be higher than head SAR indicators and body SAR indicators. SAR indicator. In the prior art, when the human body is close to the terminal device, reducing the transmit power of all antennas based on a unified index will make the terminal device unable to meet the corresponding SAR index. For example, when the head, body, or hands are close to the terminal device, Reduce the transmit power of all antennas uniformly based on the SAR index of the limbs, which will make the terminal device unable to meet the head SAR index when the head is close to the terminal device; or reduce the transmit power of the antenna in the terminal device too much, resulting in the communication of the terminal device Performance degradation affects the user’s communication experience. For example, when the head, body, or hands are close to the terminal device, the transmission power of all antennas is uniformly reduced based on the head SAR index, which will make the hand close to the terminal device. The transmission power of the antenna is reduced too much, which leads to a decrease in the communication performance of the terminal device, which is prone to problems such as network drop and call drop.
为了解决上述问题，本申请实施例提供了一种天线功率调节方法、终端设备及计算机可读存储介质，可以在终端设备的使用过程中，通过摄像头采集图像，然后进行图像分析，来确定靠近终端设备的预定目标是头部、身体还是手部，并确定与预定目标对应的、需要进行功率调节的待调节天线，从而可以根据预定目标对应的回退参数降低待调节天线的发射功率，其中，不同预定目标对应的回退参数不同。即本申请实施例可以精确确定靠近终端设备的预定目标的类型，并可以准确确定与预定目标对应的待调节天线，从而可以根据预定目标的不同基于不同的回退参数来降低待调节天线的发射功率，以在确保终端设备满足SAR指标的基础上，提高终端设备的通信性能，提升用户的通讯体验。In order to solve the above problems, the embodiments of the present application provide an antenna power adjustment method, a terminal device, and a computer-readable storage medium. During the use of the terminal device, an image can be collected through a camera, and then image analysis is performed to determine the proximity to the terminal. The predetermined target of the device is the head, body, or hand, and the antenna to be adjusted corresponding to the predetermined target that needs power adjustment is determined, so that the transmit power of the antenna to be adjusted can be reduced according to the fallback parameter corresponding to the predetermined target, where: The fallback parameters corresponding to different predetermined targets are different. That is, the embodiment of the application can accurately determine the type of the predetermined target close to the terminal device, and can accurately determine the antenna to be adjusted corresponding to the predetermined target, so that the emission of the antenna to be adjusted can be reduced based on different fallback parameters according to the predetermined target. On the basis of ensuring that the terminal equipment meets the SAR index, it can improve the communication performance of the terminal equipment and enhance the user’s communication experience.

Acquire an image collected by a camera in a terminal device, and determine a predetermined target according to the image, where the predetermined target includes at least one of a head, a body, and a hand, and the first distance between the predetermined target and the terminal device is less than the first distance between the predetermined target and the terminal device. Distance threshold.
具体地，终端设备可以包括前置摄像头和后置摄像头。在终端设备的使用过程中，前置摄像头可以进行第一图像的采集，并可以将所采集的第一图像发送至终端设备的处理器，例如NPU，后置摄像头可以进行第二图像的采集，并可以将所采集的第二图像发送至终端设备的处理器，例如NPU。NPU可以对第一图像和/或第二图像进行图像识别与分析等，确定第一图像和/或第二图像中是否存在头部、身体、手部等目标，然后再根据目标与终端设备之间的第一距离是否小于第一距离阈值来确定该目标是否靠近终端设备，并可以将靠近终端设备的目标确定为预定目标。其中，第一距离阈值可以根据实际情况确定。Specifically, the terminal device may include a front camera and a rear camera. During the use of the terminal device, the front camera can collect the first image, and can send the collected first image to the processor of the terminal device, such as the NPU, and the rear camera can collect the second image. And can send the collected second image to the processor of the terminal device, such as the NPU. The NPU can perform image recognition and analysis on the first image and/or the second image, and determine whether there are targets such as head, body, and hands in the first image and/or the second image, and then based on the relationship between the target and the terminal device. Whether the first distance between the two is smaller than the first distance threshold is used to determine whether the target is close to the terminal device, and the target close to the terminal device may be determined as a predetermined target. Among them, the first distance threshold can be determined according to actual conditions.
在此，可根据目标在第一图像/第二图像中占据的图像面积来确定目标与终端设备之间的第一距离。应理解，当目标在图像中占据的图像面积越大时，目标与终端设备之间的第一距离越小，目标距离终端设备越近；当目标在图像中占据的图像面积越小时，目标与终端设备之间的第一距离越大，目标距离终端设备越远。具体地，可以预先通过测试得到目标在图像中占据的图像面积与第一距离之间的对应关系。因此，在确定第一图像/第二图像中存在目标时，可以检测目标在第一图像/第二图像中的图像面积，并可以根据图像面积和该对应关系确定目标与终端设备之间的第一距离，以根据第一距离是否小于第一距离阈值来确定该目标是否为靠近终端设备的预定目标。Here, the first distance between the target and the terminal device can be determined according to the image area occupied by the target in the first image/second image. It should be understood that when the image area occupied by the target in the image is larger, the first distance between the target and the terminal device is smaller, and the target is closer to the terminal device; when the image area occupied by the target in the image is smaller, the target and The greater the first distance between terminal devices, the farther the target is from the terminal device. Specifically, the correspondence between the image area occupied by the target in the image and the first distance can be obtained through a test in advance. Therefore, when it is determined that there is a target in the first image/second image, the image area of the target in the first image/second image can be detected, and the first image between the target and the terminal device can be determined according to the image area and the corresponding relationship. A distance to determine whether the target is a predetermined target close to the terminal device according to whether the first distance is less than the first distance threshold.
应理解，终端设备的使用状态可以包括贴头通话状态、手持状态和放置状态，手持状态可以包括手持读屏状态和手持非读屏状态，放置状态可以包括放置于身体上的读屏状态和放置于身体上的非读屏状态，以及放置于物体上的读屏状态和放置于物体上的非读屏状态。在贴头通话状态中，例如听筒通话中，靠近终端设备的预定目标可以包括用户的头部；在手持状态中，靠近终端设备的预定目标可以包括用户的手部；在放置于身体上的读屏状态和非读屏状态中，靠近终端设备的预定目标可以包括用户的身体。It should be understood that the state of use of the terminal device may include a post-it talk state, a handheld state, and a placement state. The handheld state may include a handheld screen-reading state and a handheld non-screen-reading state. The placement state may include the screen-reading state and placement on the body. The non-screen-reading state on the body, the screen-reading state placed on the object, and the non-screen-reading state placed on the object. In the post-talk state, for example, in a handset call, the predetermined target near the terminal device may include the user's head; in the hand-held state, the predetermined target near the terminal device may include the user's hand; In the screen state and the non-screen-reading state, the predetermined target close to the terminal device may include the user's body.
需要说明的是，当终端设备处于贴头通话状态(例如听筒通话状态)时，第一图像中可以包括用户局部的头部特征(例如耳朵特征)；当终端设备处于手持读屏状态时，第一图像中可以包括用户的脸部特征，第二图像中可以包括周围的环境特征；当终端设备处于手持非读屏状态时，第一图像和第二图像中均可以包括周围的环境特征；当终端设备处于放置于身体上的读屏状态时，第一图像中可以包括用户的脸部特征，第二图像中可以包括身体特征(例如肢体轮廓特征)；当终端设备处于放置于身体上的非读屏状态时，第一图像中可以包括周围的环境特征，第二图像中可以包括身体特征(例如肢体轮廓特征)，或者第二图像中可以包括周围的环境特征，第一图像中可以包括身体特征(例如肢体轮廓特征)；当终端设备处于放置于物体上的读屏状态时，第一图像中可以包括用户的脸部特征，第二图像中可以包括物体形状特征和/或物体材质特征等；当终端设备处于放置于物体上的非读屏状态时，第一图像中可以包括周围的环境特征，第二图像中可以包括物体形状特征和/或物体材质特征等，或者第二图像中可以包括周围的环境特征，第一图像中可以包括物体形状特征和/或物体材质特征等。It should be noted that when the terminal device is in a stick-on-head talk state (for example, an earpiece talk state), the first image may include the user's partial head characteristics (for example, ear characteristics); when the terminal device is in a handheld screen-reading state, the first image One image may include the user's facial features, and the second image may include surrounding environmental characteristics; when the terminal device is in a handheld and non-reading state, both the first image and the second image may include surrounding environmental characteristics; When the terminal device is placed on the body and is in a screen-reading state, the first image may include the user's facial features, and the second image may include physical features (such as limb contour features); when the terminal device is placed on the body When reading the screen, the first image can include surrounding environment features, the second image can include physical features (such as limb contour features), or the second image can include surrounding environment features, and the first image can include the body Features (such as body contour features); when the terminal device is placed on an object and is in a screen-reading state, the first image may include the user's facial features, and the second image may include object shape features and/or object material features, etc. ; When the terminal device is placed on the object in a non-screen-reading state, the first image can include surrounding environmental features, the second image can include object shape features and/or object material features, or the second image can Including surrounding environment features, the first image may include object shape features and/or object material features, etc.
在进行预定目标的确定时，NPU可以识别第一图像中的第一目标特征，当第一目标特征为局部的头部特征时，可随即确定第一目标特征对应的头部与终端设备之间的第一距离，若第一距离小于第一距离阈值，则可以确定终端设备处于贴头通话状态，即确定靠近终端设备的预定目标包括头部。当第一目标特征为脸部特征时，可以表明用户当前正面对终端设备读屏，此时NPU可以进一步识别第二图像中的第二目标特征，当第二目标特征为环境特征时，则可以确定终端设备处于手持读屏状态，即确定靠近终端设备的预定目标包括手部；当第二目标特征为身体特征时，可随即确定第二目标特征对应的身体与终端设备之间的第一距离，若第一距离小于第一距离阈值，则可以确定终端设 备处于放置于身体上的读屏状态，即确定靠近终端设备的预定目标包括身体；当第二目标特征为物体形状特征或物体材质特征时，则可以确定终端设备处于放置于物体上的读屏状态，即确定没有靠近终端设备的预定目标。当第一目标特征为环境特征，且第二目标特征为身体特征，同时第二目标特征对应的身体与终端设备之间的第一距离小于第一距离阈值时，或者当第一目标特征为身体特征，且第一目标特征对应的身体与终端设备之间的第一距离小于第一距离阈值时，则可以确定终端设备处于放置于身体上的非读屏状态，即确定靠近终端设备的预定目标包括身体。当第一目标特征和第二目标特征均为环境特征时，则可以确定终端设备处于手持非读屏状态，即确定靠近终端设备的预定目标包括手部。当第一目标特征为环境特征，且第二目标特征为物体形状特征或物体材质特征时，或者当第二目标特征为环境特征，且第一目标特征为物体形状特征或物体材质特征时，则可以确定终端设备处于放置于物体上的非读屏状态，即确定没有靠近终端设备的预定目标。When determining the predetermined target, the NPU can identify the first target feature in the first image. When the first target feature is a local head feature, it can immediately determine the relationship between the head corresponding to the first target feature and the terminal device. If the first distance is less than the first distance threshold, it can be determined that the terminal device is in a head-to-head talk state, that is, it is determined that the predetermined target close to the terminal device includes the head. When the first target feature is a facial feature, it can indicate that the user is currently reading the screen of the terminal device. At this time, the NPU can further identify the second target feature in the second image. When the second target feature is an environmental feature, it can It is determined that the terminal device is in a handheld screen reading state, that is, it is determined that the predetermined target close to the terminal device includes a hand; when the second target feature is a physical feature, the first distance between the body corresponding to the second target feature and the terminal device can be determined immediately If the first distance is less than the first distance threshold, it can be determined that the terminal device is placed on the body to read the screen, that is, it is determined that the predetermined target close to the terminal device includes the body; when the second target feature is an object shape feature or an object material feature At the time, it can be determined that the terminal device is in a screen-reading state placed on the object, that is, it is determined that there is no predetermined target close to the terminal device. When the first target feature is an environmental feature, and the second target feature is a physical feature, and the first distance between the body corresponding to the second target feature and the terminal device is less than the first distance threshold, or when the first target feature is a body Feature, and the first distance between the body corresponding to the first target feature and the terminal device is less than the first distance threshold, it can be determined that the terminal device is placed on the body in a non-screen-reading state, that is, the predetermined target close to the terminal device is determined Including the body. When the first target feature and the second target feature are both environmental features, it can be determined that the terminal device is in a hand-held non-screen-reading state, that is, it is determined that the predetermined target close to the terminal device includes a hand. When the first target feature is an environmental feature and the second target feature is an object shape feature or an object material feature, or when the second target feature is an environmental feature, and the first target feature is an object shape feature or an object material feature, then It can be determined that the terminal device is in a non-screen-reading state placed on the object, that is, it is determined that there is no predetermined target close to the terminal device.
示例性的，为准确区分终端设备是处于手持读屏状态，还是非手持读屏状态，还可事先采集用户进行手持读屏和非手持读屏时的读屏距离，并可以根据读屏距离进行第二距离阈值的设置，使得NPU可以基于第二距离阈值和图像中的目标特征来进行手持读屏状态和非手持读屏状态的区分。其中，读屏距离是指用户的脸部与终端设备之间的距离。具体地，当第一目标特征为脸部特征时，NPU可确定第一目标特征对应的脸部与终端设备之间的距离。当第二目标特征为环境特征，且脸部与终端设备之间的距离小于或等于第二距离阈值时，则可以确定终端设备处于手持读屏状态，即确定靠近终端设备的预定目标包括手部；当第二目标特征为身体特征，且脸部与终端设备之间的距离大于第二距离阈值时，可随即确定第二目标特征对应的身体与终端设备之间的第一距离，若第一距离小于第一距离阈值，则可以确定终端设备处于放置于身体上的读屏状态，即确定靠近终端设备的预定目标包括身体。Exemplarily, in order to accurately distinguish whether the terminal device is in a handheld screen reading state or a non-handheld screen reading state, it is also possible to collect in advance the screen reading distance when the user performs hand-held screen reading and non-hand-held screen reading, and can proceed according to the screen reading distance. The setting of the second distance threshold allows the NPU to distinguish between the hand-held screen reading state and the non-hand-held screen reading state based on the second distance threshold and the target characteristics in the image. Among them, the screen reading distance refers to the distance between the user's face and the terminal device. Specifically, when the first target feature is a facial feature, the NPU may determine the distance between the face corresponding to the first target feature and the terminal device. When the second target feature is an environmental feature, and the distance between the face and the terminal device is less than or equal to the second distance threshold, it can be determined that the terminal device is in a handheld screen reading state, that is, it is determined that the predetermined target close to the terminal device includes the hand ; When the second target feature is a physical feature, and the distance between the face and the terminal device is greater than the second distance threshold, the first distance between the body and the terminal device corresponding to the second target feature can be determined immediately, if the first If the distance is less than the first distance threshold, it can be determined that the terminal device is in a screen-reading state placed on the body, that is, it is determined that the predetermined target close to the terminal device includes the body.
S202、确定与预定目标对应的待调节天线，并根据预定目标对应的回退参数降低待调节天线的发射功率。S202: Determine the antenna to be adjusted corresponding to the predetermined target, and reduce the transmit power of the antenna to be adjusted according to the backoff parameter corresponding to the predetermined target.
应理解，NPU确定靠近终端设备的预定目标后，可以将预定目标的信息发送至AP，AP则可以进一步确定与预定目标对应的待调节天线，并可以根据预定目标对应的回退参数降低待调节天线的发射功率。具体地，AP可以根据预定目标对应的回退参数和待调节天线的当前发射功率确定待调节天线的功率调节值，并可以将功率调节值发送至调制解调器Modem芯片，Modem芯片可以根据功率调节值来降低待调节天线的发射功率，以对待调节天线进行功率回退处理，从而满足对应的SAR指标。在此，预定目标对应的回退参数可以为天线的发射功率需要降低的功率值，或者可以为天线的发射功率所允许的上限值等。其中，预定目标对应的回退参数可以根据预定目标对应的SAR指标确定，例如可以根据头部SAR指标确定头部靠近终端设备时的回退参数，可以根据身体SAR指标确定身体靠近终端设备时的回退参数，可以根据四肢SAR确定手持终端设备时的回退参数。It should be understood that after the NPU determines the predetermined target close to the terminal device, it can send the information of the predetermined target to the AP, and the AP can further determine the antenna to be adjusted corresponding to the predetermined target, and can reduce the to-be-adjusted parameters according to the fallback parameter corresponding to the predetermined target. The transmit power of the antenna. Specifically, the AP can determine the power adjustment value of the antenna to be adjusted according to the fallback parameter corresponding to the predetermined target and the current transmit power of the antenna to be adjusted, and can send the power adjustment value to the modem chip, and the modem chip can determine the power adjustment value according to the power adjustment value. Reduce the transmit power of the antenna to be adjusted to perform power back-off processing on the antenna to be adjusted, so as to meet the corresponding SAR index. Here, the backoff parameter corresponding to the predetermined target may be a power value at which the transmit power of the antenna needs to be reduced, or may be an allowable upper limit of the transmit power of the antenna, or the like. Among them, the fallback parameter corresponding to the predetermined target can be determined according to the SAR indicator corresponding to the predetermined target. For example, the fallback parameter when the head is close to the terminal device can be determined according to the head SAR indicator, and the fallback parameter when the body is close to the terminal device can be determined according to the body SAR indicator. The fallback parameters can be determined according to the SAR of the limbs when holding the terminal device.
需要说明的是，本实施例中通过AP进行待调节天线和功率调节值的确定等仅作示意性解释，不应理解为对本实施例的限制，本实施例中当然也可以采用其他处理器来进行待调节天线和功率调节值的确定等，例如也可以采用协处理器(CoProcessor)来进行待调节天线和功率调节值的确定等。It should be noted that the determination of the antenna to be adjusted and the power adjustment value performed by the AP in this embodiment is only for schematic explanation, and should not be construed as a limitation of this embodiment. Of course, other processors can also be used in this embodiment. For the determination of the antenna to be adjusted and the power adjustment value, for example, a coprocessor (CoProcessor) may also be used to determine the antenna to be adjusted and the power adjustment value.
在一个示例中，如图3所示，当预定目标包括头部时，即当终端设备靠近头部使用时，头部会对屏幕内的部分光源发射的光线进行遮挡，遮挡后的光线则可反射至屏幕内。同样地，如图4a至图4c所示，当预定目标包括手部时，即当用户手持终端设备时，用户的手部也会对屏幕中的部分区域进行遮挡，从而使得屏幕内的部分光源发射的光线经手部遮挡后反射至屏幕内。因此，在确定预定目标包括头部和/或手部后，终端设备可以根据屏幕中的光线信息来确定与预定目标对应的待调节天 线。In an example, as shown in Figure 3, when the predetermined target includes the head, that is, when the terminal device is used close to the head, the head will block some of the light emitted by the light source in the screen, and the blocked light can be used. Reflected into the screen. Similarly, as shown in Figures 4a to 4c, when the predetermined target includes the hand, that is, when the user holds the terminal device, the user’s hand will also block some areas of the screen, so that part of the light source in the screen The emitted light is blocked by the hand and reflected into the screen. Therefore, after determining that the predetermined target includes the head and/or the hand, the terminal device can determine the antenna to be adjusted corresponding to the predetermined target according to the light information on the screen.
如图5所示，本实施例可以在终端设备的屏幕内设置光线传感器和屏幕驱动芯片。屏幕内的光源发射的光线经头部或手部遮挡后可以反射至光线传感器上，光线传感器可以将所获取的光线信息发送至屏幕驱动芯片，屏幕驱动芯片可以根据光线传感器发送的光线信息来确定屏幕中的遮挡区域，并可以将遮挡区域发送至AP。AP在确定预定目标包括头部或者确定预定目标包括手部时，可以根据遮挡区域来确定头部与终端设备所靠近的区域，或者手部与终端设备所靠近的区域。示例性的，可事先对终端设备的屏幕进行网格区域划分，并可以在各网格区域内设置对应的光线传感器来获取各网格区域内的光线信息，从而可快速确定屏幕中的遮挡区域。As shown in FIG. 5, in this embodiment, a light sensor and a screen driving chip can be arranged in the screen of the terminal device. The light emitted by the light source in the screen can be reflected to the light sensor after being blocked by the head or hand. The light sensor can send the acquired light information to the screen driver chip, and the screen driver chip can determine according to the light information sent by the light sensor The blocked area on the screen, and the blocked area can be sent to the AP. When the AP determines that the predetermined target includes the head or determines that the predetermined target includes the hand, it may determine the area close to the head and the terminal device, or the area close to the hand and the terminal device according to the occlusion area. Exemplarily, the screen of the terminal device can be divided into grid areas in advance, and corresponding light sensors can be set in each grid area to obtain light information in each grid area, so that the occlusion area in the screen can be quickly determined .
具体地，在确定预定目标包括头部以及根据光线传感器获取的光线信息确定出屏幕中的遮挡区域后，可随即确定遮挡区域的区域面积和区域位置，并可以根据区域面积和区域位置获取第一目标遮挡区域，第一目标遮挡区域可以为区域面积大于第一面积阈值，且区域位置为预设位置的遮挡区域。其中，第一面积阈值可通过对用户将终端设备靠近头部使用时，头部与终端设备贴近的区域面积进行分析确定。因在贴头通话时，例如听筒通话时，头部一般是贴近终端设备的上侧，因此，预设位置可设置为屏幕中靠近终端设备上边缘或者靠近前置摄像头的位置。在此，第一目标遮挡区域即为头部与终端设备所靠近的区域，即第一目标遮挡区域对应的第一目标天线即为与头部靠近的天线，因此，可以将第一目标遮挡区域对应的第一目标天线确定为与头部对应的待调节天线，并可以根据头部对应的回退参数对该待调节天线的发射功率进行调节，以使得该待调节天线的SAR满足头部SAR指标。Specifically, after the predetermined target is determined to include the head and the occlusion area in the screen is determined according to the light information obtained by the light sensor, the area area and location of the occlusion area can be determined immediately, and the first The target occluded area, the first target occluded area may be an occluded area whose area is greater than the first area threshold and the location of the area is a preset position. Wherein, the first area threshold may be determined by analyzing the area of the area where the head and the terminal device are close when the user uses the terminal device close to the head. Since the head is generally close to the upper side of the terminal device during a head-to-head call, such as a handset call, the preset position can be set to a position close to the upper edge of the terminal device or close to the front camera on the screen. Here, the first target shielding area is the area where the head is close to the terminal device, that is, the first target antenna corresponding to the first target shielding area is the antenna close to the head. Therefore, the first target shielding area can be The corresponding first target antenna is determined as the antenna to be adjusted corresponding to the head, and the transmit power of the antenna to be adjusted can be adjusted according to the back-off parameters corresponding to the head, so that the SAR of the antenna to be adjusted meets the SAR of the head index.
具体地，由图4a至图4c可知，当用户手持终端设备时，手部会对屏幕侧边形成离散的多点遮挡，和/或会对屏幕中间形成离散的单点或多点遮挡。因此，在确定预定目标包括手部以及根据光线传感器获取的光线信息确定出屏幕中的遮挡区域后，可以进一步确定遮挡区域的区域面积和区域位置，并可以根据区域面积和区域位置确定第二目标遮挡区域。其中，第二目标遮挡区域可以为区域面积小于第二面积阈值，且区域位置分布满足预设条件的遮挡区域。预设条件可以为手部持握终端设备时手指、手掌等部位在屏幕中的位置分布，例如可以为屏幕左侧边、右侧边和/或屏幕中间具有的单点或多点的位置分布等。在此，第二目标遮挡区域即为手部与终端设备所靠近的区域，因此，可以将第二目标遮挡区域对应的第二目标天线确定为与手部对应的待调节天线，并可以根据手部对应的回退参数对该待调节天线的发射功率进行调节，以使得该待调节天线的SAR满足手部SAR指标。其中，第二面积阈值可以通过对用户手持终端设备时，用户手部与屏幕所形成的接触面积或遮挡面积进行分析确定，第二面积阈值小于头部中的第一面积阈值。Specifically, it can be seen from FIGS. 4a to 4c that when the user holds the terminal device, the hand forms discrete multi-point shielding on the sides of the screen, and/or discrete single-point or multi-point shielding on the middle of the screen. Therefore, after the predetermined target is determined to include the hand and the occlusion area in the screen is determined based on the light information obtained by the light sensor, the area and location of the occlusion area can be further determined, and the second target can be determined according to the area and location Block the area. Wherein, the second target shielding area may be a shielding area whose area is smaller than the second area threshold and the location distribution of the area satisfies a preset condition. The preset condition can be the position distribution of fingers, palms and other parts on the screen when the terminal device is held by the hand. For example, it can be the position distribution of a single point or multiple points on the left side, right side of the screen, and/or in the middle of the screen. Wait. Here, the second target shielding area is the area where the hand is close to the terminal device. Therefore, the second target antenna corresponding to the second target shielding area can be determined as the antenna to be adjusted corresponding to the hand, and can be adjusted according to the hand The backoff parameter corresponding to the part adjusts the transmit power of the antenna to be adjusted so that the SAR of the antenna to be adjusted meets the hand SAR index. Wherein, the second area threshold may be determined by analyzing the contact area or occlusion area formed by the user's hand and the screen when the user holds the terminal device, and the second area threshold is smaller than the first area threshold in the head.
应理解，第一目标遮挡区域对应的第一目标天线和第二目标遮挡区域对应的第二目标天线可以根据屏幕区域与天线之间的映射关系确定，即可以事先建立屏幕区域与天线之间的映射关系保存于终端设备。在确定出第一目标遮挡区域或第二目标遮挡区域后，终端设备可以根据该映射关系确定第一目标遮挡区域对应的第一目标天线，或第二目标遮挡区域对应的第二目标天线。It should be understood that the first target antenna corresponding to the first target shielding area and the second target antenna corresponding to the second target shielding area can be determined according to the mapping relationship between the screen area and the antenna, that is, the relationship between the screen area and the antenna can be established in advance. The mapping relationship is stored in the terminal device. After determining the first target occlusion area or the second target occlusion area, the terminal device may determine the first target antenna corresponding to the first target occlusion area or the second target antenna corresponding to the second target occlusion area according to the mapping relationship.
在一个示例中，当有目标紧贴终端设备中的某一天线时，该天线的阻抗会发生较大变化。而在预定目标包括头部时，即在终端设备靠近头部使用时，头部一般会紧贴终端设备的上侧，使得头部所贴近的天线的阻抗会发生较大变化。同样地，在用户手持终端设备时，若手部持握的位置中包括天线，则该天线的阻抗也会发生较大变化。因此，在确定预定目标包括头部和/或手部时，终端设备还可以根据各天线的阻抗变化值来确定与预定目标对应的待调节天线。In an example, when a target is close to a certain antenna in the terminal device, the impedance of the antenna will change greatly. When the predetermined target includes the head, that is, when the terminal device is used close to the head, the head generally closes to the upper side of the terminal device, so that the impedance of the antenna close to the head changes greatly. Similarly, when the user holds the terminal device, if the position where the hand holds the antenna includes an antenna, the impedance of the antenna will also change significantly. Therefore, when it is determined that the predetermined target includes the head and/or the hand, the terminal device may also determine the antenna to be adjusted corresponding to the predetermined target according to the impedance change value of each antenna.
具体地，如图5所示，终端设备内可设置Modem芯片，Modem芯片与天线之间可以通过射频传 输线连接，Modem芯片可以获取终端设备中各天线的阻抗变化值，并可以将各天线的阻抗变化值和其所对应的位置信息发送至AP。AP则可以确定阻抗变化值大于预设变化阈值的第三目标天线，并可以根据第三目标天线的位置信息确定与预定目标对应的待调节天线。其中，预设变化阈值可以根据实际情况确定。Specifically, as shown in Figure 5, a Modem chip can be set in the terminal device, and the Modem chip and the antenna can be connected through a radio frequency transmission line. The Modem chip can obtain the impedance change value of each antenna in the terminal device, and the The change value and its corresponding location information are sent to the AP. The AP may determine the third target antenna whose impedance change value is greater than the preset change threshold, and may determine the antenna to be adjusted corresponding to the predetermined target according to the position information of the third target antenna. Among them, the preset change threshold can be determined according to actual conditions.
例如，可以将位于终端设备上边缘的第三目标天线确定为与头部对应的待调节天线。例如，可以将位于终端设备左侧边、右侧边和/或下边缘的第三目标天线确定为与手部对应的待调节天线。For example, the third target antenna located at the upper edge of the terminal device may be determined as the antenna to be adjusted corresponding to the head. For example, the third target antenna located on the left side, right side, and/or lower edge of the terminal device may be determined as the antenna to be adjusted corresponding to the hand.
示例性的，在预定目标包括头部和/或手部时，终端设备也可以结合屏幕中的光线信息和天线的阻抗变化值来确定与预定目标对应的待调节天线。例如，在预定目标包括头部时，可以先根据屏幕中的光线信息和各天线的阻抗变化值分别确定出第一目标天线和第三目标天线，然后可以将第一目标天线和第三目标天线统一确定为与头部对应的待调节天线；或者可以将第一目标天线和第三目标天线中所重叠的天线确定为与头部对应的待调节天线，如当第一目标天线中包括天线1、天线2和天线3，第三目标天线中包括天线1和天线3时，则可以将天线1和天线3确定为与头部对应的待调节天线。例如，在预定目标包括头部时，也可以先根据屏幕中的光线信息确定第一目标遮挡区域，然后可以获取第一目标遮挡区域对应的第一目标天线的阻抗变化值，并可以将阻抗变化值大于预设变化阈值的第一目标天线确定为头部对应的待调节天线。Exemplarily, when the predetermined target includes the head and/or the hand, the terminal device may also combine the light information on the screen and the impedance change value of the antenna to determine the antenna to be adjusted corresponding to the predetermined target. For example, when the predetermined target includes the head, the first target antenna and the third target antenna can be determined according to the light information on the screen and the impedance change value of each antenna, and then the first target antenna and the third target antenna can be combined. Unifiedly determine the antenna to be adjusted corresponding to the head; or the overlapping antenna of the first target antenna and the third target antenna may be determined as the antenna to be adjusted corresponding to the head, for example, when the first target antenna includes antenna 1 , Antenna 2 and antenna 3, when the third target antenna includes antenna 1 and antenna 3, antenna 1 and antenna 3 can be determined as the antenna to be adjusted corresponding to the head. For example, when the predetermined target includes the head, the first target occlusion area can also be determined according to the light information on the screen, and then the impedance change value of the first target antenna corresponding to the first target occlusion area can be obtained, and the impedance can be changed The first target antenna whose value is greater than the preset change threshold is determined as the antenna to be adjusted corresponding to the head.
应理解，当终端设备处于贴头通话状态时，还可以伴随有手持状态。因此，在根据第一图像确定预定目标包括头部时，可以在根据屏幕中的光线信息和/或天线的阻抗变化值确定头部与终端设备所靠近的区域时，根据屏幕中的光线信息和/或天线的阻抗变化值确定是否存在手部持握终端设备的情况，以及当存在手部持握终端设备的情况时，确定手部在终端设备中所持握的区域。因此，在预定目标包括头部和手部时,可以根据头部与终端设备靠近的区域确定与头部对应的第一待调节天线以及根据手部在终端设备中所持握的区域确定与手部对应的第二待调节天线，并可以根据头部SAR对第一待调节天线进行发射功率的调节，以使得靠近头部的第一待调节天线满足头部SAR指标，同时可以根据四肢SAR对第二待调节天线进行发射功率的调节，以使得靠近手部的第二待调节天线满足四肢SAR指标。It should be understood that when the terminal device is in a stick-to-head talk state, it may also be accompanied by a hand-held state. Therefore, when it is determined that the predetermined target includes the head according to the first image, the area between the head and the terminal device can be determined according to the light information on the screen and/or the impedance change value of the antenna. /Or the impedance change value of the antenna determines whether there is a situation where the hand is holding the terminal device, and when there is a situation where the hand is holding the terminal device, the area where the hand is held in the terminal device is determined. Therefore, when the predetermined target includes the head and the hand, the first antenna to be adjusted corresponding to the head can be determined according to the area close to the head and the terminal device, and the first antenna to be adjusted can be determined according to the area held by the hand in the terminal device. The corresponding second antenna to be adjusted can adjust the transmit power of the first antenna to be adjusted according to the SAR of the head, so that the first antenna to be adjusted close to the head meets the head SAR index, and at the same time, the first antenna to be adjusted can be adjusted according to the SAR of the extremities. The second antenna to be adjusted adjusts the transmission power, so that the second antenna to be adjusted close to the hand meets the SAR index of the limbs.
需要说明的是，在根据屏幕中的光线信息确定头部和/或手部靠近终端设备的区域时，若终端设备当前处于灭屏状态，则可以根据屏幕灭屏的前一刻，光线传感器所获取的光线信息来确定头部和/或手部靠近终端设备的区域。It should be noted that when the area where the head and/or hands are close to the terminal device is determined according to the light information on the screen, if the terminal device is currently in the off-screen state, it can be obtained according to the light sensor immediately before the screen is off Light information to determine the area of the head and/or hands close to the terminal device.
在一个示例中，当终端设备的屏幕为电容屏时，若有目标与屏幕中的某一区域接触，该区域即会产生电容变化。而在预定目标包括头部或手部时，即在终端设备靠近头部或靠近手部使用时，头部或手部一般会与屏幕中的部分区域接触，从而使得该区域产生电容变化。因此，终端设备还可以根据屏幕的电容变化以及变化区域来确定与头部或与手部对应的待调节天线。例如，可以将符合人手持握姿态的变化区域所对应的天线确定为与手部对应的待调节天线。例如，可以将靠近终端设备上侧的变化区域所对应的天线确定为与头部对应的待调节天线，等等。In an example, when the screen of the terminal device is a capacitive screen, if a target touches a certain area of the screen, the area will produce a capacitance change. When the predetermined target includes the head or the hand, that is, when the terminal device is used close to the head or close to the hand, the head or the hand generally touches a part of the area on the screen, which causes a capacitance change in this area. Therefore, the terminal device can also determine the antenna to be adjusted corresponding to the head or the hand according to the capacitance change and the change area of the screen. For example, the antenna corresponding to the change area that conforms to the hand-held posture of a person may be determined as the antenna to be adjusted corresponding to the hand. For example, the antenna corresponding to the change area close to the upper side of the terminal device may be determined as the antenna to be adjusted corresponding to the head, and so on.
类似地，当终端设备的屏幕为电阻屏时，若有目标与屏幕的某一区域接触时，该区域即会产生电阻变化，因此，对于具有电阻屏的终端设备则可以根据电阻变化以及变化区域来确定与头部或手部对应的待调节天线。其中，电阻屏的确定原理与上述电容屏的确定原理基本相同，在此不再赘述。Similarly, when the screen of the terminal device is a resistive screen, if a target touches a certain area of the screen, the area will have a resistance change. Therefore, for a terminal device with a resistive screen, it can be based on the resistance change and the change area. To determine the antenna to be adjusted corresponding to the head or hand. Among them, the determination principle of the resistive screen is basically the same as the determination principle of the above-mentioned capacitive screen, and will not be repeated here.
应理解，当预定目标仅包括身体时，则可直接将终端设备中的所有天线均确定为与身体对应的待调节天线，从而可根据身体对应的回退参数统一降低各待调节天线的发射功率，以使得待调节天线的SAR满足身体SAR指标。It should be understood that when the predetermined target only includes the body, all antennas in the terminal device can be directly determined as the antennas to be adjusted corresponding to the body, so that the transmit power of the antennas to be adjusted can be uniformly reduced according to the back-off parameters corresponding to the body. , So that the SAR of the antenna to be adjusted meets the body SAR index.
需要说明的是，在对待调节天线的发射功率进行降低之后，可以获取终端设备中各天线当前的发射功率，并可以根据各天线当前的发射功率对终端设备的发射天线进行切换，以将终端设备的发射天线切换至发射功率较高的天线，从而提高终端设备的通信性能，以提升用户的通讯体验。示例性的，Modem芯片与天线之间还可以连接有功率放大器、射频开关、低噪放等射频器件。在需要进行发射天线的切换时，AP可以通过Modem芯片调整射频开关的开关状态来进行发射天线的切换，或者可以通过Modem芯片选择不同的射频通路来进行发射天线的切换。It should be noted that after the transmit power of the antenna to be adjusted is reduced, the current transmit power of each antenna in the terminal device can be obtained, and the transmit antenna of the terminal device can be switched according to the current transmit power of each antenna to switch the terminal device The transmitting antenna of the switch is switched to an antenna with a higher transmitting power, thereby improving the communication performance of the terminal device to enhance the user's communication experience. Exemplarily, a power amplifier, a radio frequency switch, a low noise amplifier and other radio frequency devices may also be connected between the modem chip and the antenna. When the transmitting antenna needs to be switched, the AP can adjust the switch state of the radio frequency switch through the Modem chip to switch the transmit antenna, or can select different radio frequency paths through the Modem chip to switch the transmit antenna.
需要说明的是，在对待调节天线的发射功率进行降低之后,为进一步降低天线产生的电磁辐射对用户的影响，可以获取终端设备中各天线与预定目标之间的第二距离，并可以根据第二距离对终端设备的发射天线进行切换，以将终端设备的发射天线切换至距离预定目标较远的天线。例如，在头部靠近终端设备时，可以将发射天线由位于终端设备上侧靠近头部的天线切换至终端设备下侧远离头部的天线，或者切换至终端设备背部的天线。例如，在手部持握终端设备时，可以将发射天线由被手部持握的天线切换至没有被手部持握的天线。It should be noted that after the transmit power of the antenna to be adjusted is reduced, in order to further reduce the influence of the electromagnetic radiation generated by the antenna on the user, the second distance between each antenna in the terminal device and the predetermined target can be obtained, and the second distance can be obtained according to the first The second distance is to switch the transmitting antenna of the terminal device to switch the transmitting antenna of the terminal device to an antenna farther from the predetermined target. For example, when the head is close to the terminal device, the transmitting antenna can be switched from the antenna on the upper side of the terminal device close to the head to the antenna on the lower side of the terminal device away from the head, or switch to the antenna on the back of the terminal device. For example, when the terminal device is held by the hand, the transmitting antenna can be switched from the antenna held by the hand to the antenna not held by the hand.
本实施例中，可通过获取摄像头采集的图像，并进行图像分析，来确定靠近终端设备的预定目标是头部、身体还是手部，并确定与预定目标对应的、需要进行功率调节的待调节天线，从而可以根据预定目标对应的回退参数降低待调节天线的发射功率，其中，不同预定目标对应的回退参数不同。即本实施例可以精确确定靠近终端设备的预定目标的类型，并可以准确确定与预定目标对应的待调节天线，从而可以根据预定目标的不同基于不同的回退参数来降低待调节天线的发射功率，以在确保终端设备满足SAR指标的基础上，提高终端设备的通信性能，提升用户的通讯体验。In this embodiment, the image collected by the camera can be acquired and image analysis can be performed to determine whether the predetermined target close to the terminal device is the head, body, or hand, and to determine the power adjustment to be adjusted corresponding to the predetermined target. The antenna can thereby reduce the transmit power of the antenna to be adjusted according to the back-off parameter corresponding to the predetermined target, wherein the back-off parameter corresponding to different predetermined targets is different. That is, this embodiment can accurately determine the type of the predetermined target close to the terminal device, and can accurately determine the antenna to be adjusted corresponding to the predetermined target, so that the transmit power of the antenna to be adjusted can be reduced based on different fallback parameters according to the predetermined target. , On the basis of ensuring that the terminal equipment meets the SAR indicator, improve the communication performance of the terminal equipment and enhance the user's communication experience.
【实施例二】[Embodiment 2]
请参阅图6，图6示出了本实施例提供的天线功率调节方法的示意性流程图。本实施例与实施例一的区别在于，本实施例中，可以获取摄像头采集的图像和屏幕中的光线信息，并可以根据图像和光线信息来进行预定目标的确定，以提高预定目标确定的准确性。下述主要描述本实施例与实施例一之间的区别部分，对于相同部分则可以直接参照上述实施例一中的描述，在此不再赘述。如图6所示，该方法可以包括：Please refer to FIG. 6, which shows a schematic flowchart of the antenna power adjustment method provided in this embodiment. The difference between this embodiment and the first embodiment is that in this embodiment, the image collected by the camera and the light information in the screen can be obtained, and the predetermined target can be determined according to the image and light information, so as to improve the accuracy of the predetermined target determination. sex. The following mainly describes the differences between this embodiment and the first embodiment, and for the same parts, you can directly refer to the description in the above-mentioned embodiment 1, which will not be repeated here. As shown in Figure 6, the method may include:

S603、当第一目标特征为头部特征，且第一目标特征对应的头部与终端设备之间的第一距离小于第一距离阈值时，确定预定目标包括头部。S603: When the first target feature is a head feature, and the first distance between the head corresponding to the first target feature and the terminal device is less than the first distance threshold, determine that the predetermined target includes a head.
其中，S601至S603可参见前述S101中的具体描述，为简明起见，在此不再赘述。Among them, S601 to S603 can refer to the specific description in the foregoing S101, for the sake of brevity, the details are not repeated here.
S604、当第一目标特征为脸部特征时，根据屏幕中的光线信息获取屏幕中的遮挡区域，并确定遮挡区域的区域面积和区域位置。S604: When the first target feature is a facial feature, obtain the occlusion area in the screen according to the light information on the screen, and determine the area area and the location of the occlusion area.
S605、若区域面积小于第二面积阈值，且区域位置分布满足第一预设条件，则确定预设目标包括手部。S605: If the area of the area is smaller than the second area threshold, and the area location distribution meets the first preset condition, determine that the preset target includes a hand.
应理解，当第一目标特征为脸部特征时，则表明用户正面对屏幕读屏，即终端设备处于读屏状态，而读屏状态可以包括手持读屏状态、放置于身体上的读屏状态以及放置于物体上的读屏状态。当终端设备处于手持读屏状态时，用户的手部会对屏幕中的部分区域进行遮挡，从而使得屏幕内部分光源发射的光线经手部遮挡后反射至屏幕内的光线传感器。因此，可以根据光线传感器获取的光线信息来确定屏幕中的遮挡区域，以确定终端设备是否处于手持读屏状态。It should be understood that when the first target feature is a facial feature, it indicates that the user is facing the screen reading, that is, the terminal device is in the screen reading state, and the screen reading state may include the hand-held screen reading state and the screen reading state placed on the body. And the screen reading status placed on the object. When the terminal device is in a handheld screen reading state, the user's hand will block a part of the screen, so that the light emitted by a part of the light source in the screen is blocked by the hand and reflected to the light sensor in the screen. Therefore, the occlusion area in the screen can be determined according to the light information obtained by the light sensor to determine whether the terminal device is in a handheld screen reading state.
具体地，在终端设备处于手持读屏状态时，手部会对屏幕侧边形成离散的多点遮挡，和/或会对屏幕中间形成离散的单点或多点遮挡。因此，可通过光线传感器获取屏幕中的光线信息，根据光线信息确定屏幕中的遮挡区域，并确定遮挡区域的区域面积和区域位置，以根据区域面积和区域位置来确定终端设备是否处于手持读屏状态。在此，当存在区域面积小于第二面积阈值，且小于第二面积阈值的这些区域的区域位置分布满足第一预设条件时，则可以确定终端设备处于手持读屏状态，即靠近终端设备的预定目标包括手部。其中，第一预设条件可以与实施例一中描述的预设条件相同，即第一预设条件可以为手部持握终端设备时手指、手掌等部位在屏幕中的位置分布，例如可以为屏幕左侧边、右侧边和/或屏幕中间具有的单点或多点的位置分布等。Specifically, when the terminal device is in a handheld screen reading state, the hand will form discrete multi-point shielding on the sides of the screen, and/or will form a discrete single-point or multi-point shielding on the middle of the screen. Therefore, the light information on the screen can be acquired through the light sensor, the shielding area in the screen can be determined according to the light information, and the area area and position of the shielding area can be determined, so as to determine whether the terminal device is in a handheld screen reading according to the area area and area position state. Here, when the area of the existing area is less than the second area threshold, and the area location distribution of these areas less than the second area threshold meets the first preset condition, it can be determined that the terminal device is in a handheld screen reading state, that is, the terminal device is close to the terminal device. The intended target includes hands. The first preset condition may be the same as the preset condition described in Embodiment 1. That is, the first preset condition may be the position distribution of fingers, palms, etc. on the screen when the terminal device is held by the hand. For example, it may be The position distribution of single or multiple points on the left side, right side of the screen, and/or the middle of the screen, etc.
S606、若区域面积大于或等于第二面积阈值，或区域位置分布不满足第一预设条件，且第二目标特征为身体特征，则确定预定目标包括身体。S606: If the area of the area is greater than or equal to the second area threshold, or the location distribution of the area does not meet the first preset condition, and the second target feature is a physical feature, it is determined that the predetermined target includes a body.
在此，当遮挡区域的区域面积大于或等于第二面积阈值，或区域位置分布不满足第一预设条件时，则可以认为光线传感器获取的光线信息不是手部遮挡所反射的，即可以确定终端设备不是处于手持读屏状态。此时，可以根据后置摄像头采集的第二图像中的第二目标特征来确定终端设备是处于放置于身体上的读屏状态还是放置于物体上的读屏状态。Here, when the area of the occluded area is greater than or equal to the second area threshold, or the area location distribution does not meet the first preset condition, it can be considered that the light information acquired by the light sensor is not reflected by the hand occlusion, and it can be determined The terminal device is not in a handheld screen-reading state. At this time, it can be determined whether the terminal device is in the screen-reading state placed on the body or the screen-reading state placed on the object according to the second target feature in the second image collected by the rear camera.
应理解，当终端设备处于放置于身体上的读屏状态时，后置摄像头所采集的第二图像中可以包括用户的身体特征(例如肢体轮廓特征)。因此，当第二目标特征为用户的身体特征时，则可以确定终端设备处于放置于身体上的读屏状态，则可以确定靠近终端设备的预定目标包括用户的身体。而当第二目标特征不是用户的身体特征，例如为物体形状特征和/或物体材质特征时，则可以确定终端设备处于放置于物体上的读屏状态，即确定不存在靠近终端设备的预定目标，此时可不用对终端设备中的天线进行发射功率的调节。It should be understood that when the terminal device is in a screen-reading state placed on the body, the second image collected by the rear camera may include the user's physical characteristics (for example, limb contour characteristics). Therefore, when the second target feature is the physical feature of the user, it can be determined that the terminal device is in a screen-reading state placed on the body, and it can be determined that the predetermined target close to the terminal device includes the user's body. When the second target feature is not a user's physical feature, such as an object shape feature and/or an object material feature, it can be determined that the terminal device is in a screen-reading state placed on the object, that is, it is determined that there is no predetermined target close to the terminal device. At this time, there is no need to adjust the transmit power of the antenna in the terminal device.
S607、当第一目标特征为环境特征，第二目标特征为身体特征，且第二目标特征对应的身体与终端设备之间的第一距离小于第一距离阈值时，或者当第一目标特征为身体特征，且第一目标特征对应的身体与终端设备之间的第一距离小于第一距离阈值时，则确定预定目标包括身体。S607. When the first target feature is an environmental feature, the second target feature is a physical feature, and the first distance between the body corresponding to the second target feature and the terminal device is less than the first distance threshold, or when the first target feature is Body characteristics, and when the first distance between the body corresponding to the first target characteristic and the terminal device is less than the first distance threshold, it is determined that the predetermined target includes a body.
S608、当第一目标特征和第二目标特征均为环境特征时，则确定预定目标包括手部。S608: When the first target feature and the second target feature are both environmental features, it is determined that the predetermined target includes a hand.
其中，S607和S608可参见前述S101中的具体描述，为简明起见，在此不再赘述。Among them, S607 and S608 can be referred to the specific description in the foregoing S101, for the sake of brevity, the details are not repeated here.
本实施例中，可以获取摄像头采集的图像以及获取屏幕中的光线信息，并可以根据图像和光线信息来进行预定目标的确定，可以提高预定目标确定的准确性，从而提高待调节天线发射功率的调节准确性。In this embodiment, the image collected by the camera and the light information on the screen can be acquired, and the predetermined target can be determined according to the image and light information, which can improve the accuracy of the predetermined target determination, thereby increasing the transmission power of the antenna to be adjusted. Adjust the accuracy.
【实施例三】[Embodiment Three]
请参阅图7，图7示出了本实施例提供的天线功率调节方法的示意性流程图。本实施例与实施例一的区别在于，本实施例中，可以获取摄像头采集的图像和终端设备中各天线的阻抗变化值，并可以根据图像和阻抗变化值来进行预定目标的确定，以提高预定目标确定的准确性。下述主要描述本实施例与实施例一之间的区别部分，对于相同部分则可以直接参照上述实施例一中的描述，在此不再赘述。如图7所示，该方法可以包括：Please refer to FIG. 7, which shows a schematic flowchart of the antenna power adjustment method provided in this embodiment. The difference between this embodiment and the first embodiment is that in this embodiment, the image collected by the camera and the impedance change value of each antenna in the terminal device can be acquired, and the predetermined target can be determined according to the image and the impedance change value to improve The accuracy of the predetermined target determination. The following mainly describes the differences between this embodiment and the first embodiment, and for the same parts, you can directly refer to the description in the above-mentioned embodiment 1, which will not be repeated here. As shown in Figure 7, the method may include:
S701、获取终端设备中摄像头采集的图像，其中，图像包括前置摄像头采集的第一图像和后置摄像头采集的第二图像。S701. Acquire an image collected by a camera in a terminal device, where the image includes a first image collected by a front camera and a second image collected by a rear camera.
S702、识别第一图像中的第一目标特征和第二图像中的第二目标特征。S702: Identify the first target feature in the first image and the second target feature in the second image.
S703、当第一目标特征为头部特征，且第一目标特征对应的头部与所述终端设备之间的第一距离小于第一距离阈值时，确定预定目标包括头部。S703: When the first target feature is a head feature, and the first distance between the head corresponding to the first target feature and the terminal device is less than a first distance threshold, determine that the predetermined target includes a head.
其中，S701至S703可参见前述S101中的具体描述，为简明起见，在此不再赘述。Among them, S701 to S703 can be referred to the specific description in the foregoing S101, for the sake of brevity, the details are not repeated here.
S704、当第一目标特征为脸部特征时，根据终端设备中各天线的阻抗变化值确定目标天线，目标天线为阻抗变化值大于预设变化阈值的天线。S704: When the first target feature is a facial feature, determine the target antenna according to the impedance change value of each antenna in the terminal device, and the target antenna is an antenna whose impedance change value is greater than a preset change threshold.
S705、若目标天线的位置分布满足第二预设条件，则确定预设目标包括手部。S705: If the position distribution of the target antenna meets the second preset condition, determine that the preset target includes a hand.
应理解，当第一目标特征为脸部特征时，则表明用户正面对屏幕读屏，即终端设备处于读屏状态，而读屏状态可以包括手持读屏状态、放置于身体上的读屏状态以及放置于物体上的读屏状态。当终端设备处于手持读屏状态时，用户的手部一般会接触终端设备的部分区域，从而使得该部分区域对应的天线的阻抗会发生较大变化。因此，终端设备可以根据各天线的阻抗变化值来确定手部持握终端设备的区域，以确定终端设备是否处于手持读屏状态。具体地，可以确定终端设备中阻抗变化值大于预设变化阈值的目标天线，并获取目标天线的位置信息，当根据位置信息确定目标天线的位置分布满足第二预设条件时，则可以确定终端设备处于手持读屏状态，即确定靠近终端设备的预定目标包括手部。其中，第二预设条件可以为手部持握终端设备时手部持握天线的位置分布。It should be understood that when the first target feature is a facial feature, it indicates that the user is facing the screen reading, that is, the terminal device is in the screen reading state, and the screen reading state may include the hand-held screen reading state and the screen reading state placed on the body. And the screen reading status placed on the object. When the terminal device is in a handheld screen reading state, the user's hand generally touches a part of the terminal device, so that the impedance of the antenna corresponding to this part of the area will change greatly. Therefore, the terminal device can determine the area where the hand holds the terminal device according to the impedance change value of each antenna, so as to determine whether the terminal device is in a handheld screen reading state. Specifically, the target antenna whose impedance change value is greater than the preset change threshold in the terminal device can be determined, and the position information of the target antenna can be obtained. When the position distribution of the target antenna is determined to meet the second preset condition according to the position information, the terminal can be determined The device is in a handheld screen reading state, that is, it is determined that the predetermined target close to the terminal device includes the hand. Wherein, the second preset condition may be the position distribution of the antenna held by the hand when the terminal device is held by the hand.
S706、若目标天线的位置分布不满足第二预设条件，且第二目标特征为身体特征，则确定预定目标包括身体。S706: If the position distribution of the target antenna does not satisfy the second preset condition, and the second target feature is a physical feature, it is determined that the predetermined target includes a body.
在此，当目标天线的位置分布不满足第二预设条件时，则可以认为终端设备中天线的阻抗变化值不是手部持握终端设备所产生的，即可以确定终端设备不是处于手持读屏状态。此时，则可以根据后置摄像头采集的第二图像中的第二目标特征来确定终端设备是处于放置于身体上的读屏状态还是放置于物体上的读屏状态。Here, when the location distribution of the target antenna does not meet the second preset condition, it can be considered that the impedance change value of the antenna in the terminal device is not caused by holding the terminal device by hand, and it can be determined that the terminal device is not in the handheld screen reading mode. state. At this time, it can be determined whether the terminal device is in the screen reading state placed on the body or the screen reading state placed on the object according to the second target feature in the second image collected by the rear camera.
应理解，当终端设备处于放置于身体上的读屏状态时，后置摄像头所采集的第二图像中可以包括用户的身体特征(例如肢体轮廓特征)。因此，当第二目标特征为用户的身体特征时，则可以确定终端设备处于放置于身体上的读屏状态，则可以确定靠近终端设备的预定目标包括用户的身体。而当第二目标特征不是用户的身体特征，例如为物体形状特征和/或物体材质特征时，则可以确定终端设备处于放置于物体上的读屏状态，即确定不存在靠近终端设备的预定目标，此时可不用对终端设备中的天线进行发射功率的调节。It should be understood that when the terminal device is in a screen-reading state placed on the body, the second image collected by the rear camera may include the user's physical characteristics (for example, limb contour characteristics). Therefore, when the second target feature is the physical feature of the user, it can be determined that the terminal device is in a screen-reading state placed on the body, and it can be determined that the predetermined target close to the terminal device includes the user's body. When the second target feature is not a user's physical feature, such as an object shape feature and/or an object material feature, it can be determined that the terminal device is in a screen-reading state placed on the object, that is, it is determined that there is no predetermined target close to the terminal device. At this time, there is no need to adjust the transmit power of the antenna in the terminal device.
S707、当第一目标特征为环境特征，第二目标特征为身体特征，且第二目标特征对应的身体与终端设备之间的第一距离小于第一距离阈值时，或者当第一目标特征为身体特征，且第一目标特征对应的身体与终端设备之间的第一距离小于第一距离阈值时，则确定预定目标包括身体。S707. When the first target feature is an environmental feature, the second target feature is a physical feature, and the first distance between the body corresponding to the second target feature and the terminal device is less than the first distance threshold, or when the first target feature is Body characteristics, and when the first distance between the body corresponding to the first target characteristic and the terminal device is less than the first distance threshold, it is determined that the predetermined target includes a body.
S708、当第一目标特征和第二目标特征均为环境特征时，则确定预定目标包括手部。S708: When the first target feature and the second target feature are both environmental features, it is determined that the predetermined target includes a hand.
其中，S707和S708可参见前述S101中的具体描述，为简明起见，在此不再赘述。Among them, S707 and S708 can be referred to the specific description in the foregoing S101, and for the sake of brevity, they are not repeated here.
本实施例中，可以获取摄像头采集的图像和终端设备中各天线的阻抗变化值，并可以根据图像和阻抗变化值来进行预定目标的确定，可以提高预定目标确定的准确性，从而提高待调节天线发射功率的调节准确性。In this embodiment, the image collected by the camera and the impedance change value of each antenna in the terminal device can be obtained, and the predetermined target can be determined according to the image and the impedance change value, which can improve the accuracy of the predetermined target determination, thereby improving the need to adjust The adjustment accuracy of the antenna transmit power.
在一个示例中，本申请实施例也可以基于图像和电容变化/电阻变化来确定预定目标。示例性的，当第一目标特征为脸部特征时，终端设备可以获取屏幕中的电容变化/电阻变化的变化区域，并可以确定变化区域的区域位置。在区域位置分布满足第三预设条件时，可以确定预设目标包括手部。其中，第三预设条件可以与第一预设条件相同，即第三预设条件可以为手部持握终端设备时手指、手掌等部位触摸屏幕的位置分布。In an example, the embodiment of the present application may also determine the predetermined target based on the image and the capacitance change/resistance change. Exemplarily, when the first target feature is a facial feature, the terminal device can acquire the change area of the capacitance change/resistance change on the screen, and can determine the location of the change area. When the regional location distribution satisfies the third preset condition, it may be determined that the preset target includes a hand. The third preset condition may be the same as the first preset condition, that is, the third preset condition may be the position distribution of the fingers, palms and other parts of the touch screen when the terminal device is held by the hand.
在一个示例中，本申请实施例也可以结合屏幕中的光线信息、各天线的阻抗变化值和图像来确定预定目标。示例性的，在第一目标特征为脸部特征时，终端设备可以根据屏幕中的光线信息获取 屏幕中的遮挡区域，并可以确定遮挡区域的区域面积和区域位置，同时可以根据终端设备中各天线的阻抗变化值确定目标天线,当区域面积小于第二面积阈值，且区域位置分布满足第一预设条件，同时目标天线的位置分布满足第二预设条件，则确定预设目标包括手部。In an example, the embodiment of the present application may also combine the light information on the screen, the impedance change value of each antenna, and the image to determine the predetermined target. Exemplarily, when the first target feature is a facial feature, the terminal device can obtain the occlusion area in the screen according to the light information on the screen, and can determine the area and location of the occlusion area.
