Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In an embodiment of the present application, there is provided an electronic device, referring to fig. 1, including:
a first body 10;
and a first sensor 11 disposed on the first body 10 and having a specific installation angle with respect to the plane of the first body 10, for obtaining distance information between the target and the electronic device.
The specific installation angle is an angle that enables the first sensor 11 to acquire information on the distance between the target and the electronic device within a specific range. The first sensor 11 may be a distance measuring sensor, or may be a sensor for performing indirect distance calculation, for example, the first sensor includes, but is not limited to, an ultrasonic distance measuring sensor, a laser distance measuring sensor, an infrared distance measuring sensor, a Time of flight (TOF) sensor, and the like.
Because the first sensor 11 and the plane of the first body 10 have a specific installation angle, and based on the specific installation angle, the first sensor can acquire the relevant distance information of the target in a specific range. The specific range ensures the range of the user in different use states, and the influence on the user in different use states is mainly determined by the use angle of the electronic equipment. The first sensor in the prior art is usually mounted on the plane of the first body, and the distance detection to the target is inaccurate because the use angle of the electronic device is not considered. In the embodiment corresponding to the present disclosure, due to the existence of the specific installation angle, it can be ensured that the electronic device accurately identifies the target at a normal use angle, and measures the relevant distance information to the target.
Wherein the specific installation angle is determined according to the commonly used angle of the electronic equipment and the ranging principle of the first sensor. The specific value of the specific installation angle may vary for different electronic devices. If the electronic device is a device including only one body, such as a smart phone, a tablet computer, an electronic book, etc., the specific installation angle needs to be determined according to the angle information of the user when using the electronic device as a design condition; for an electronic device including two bodies, such as a notebook computer, the use angle between the display screen and the user needs to be determined. And, the first sensor corresponding to different distance measuring principles needs to take the influence of the distance measuring light path into consideration in determining the value of the specific installation angle.
It should be noted that, in the embodiment of the present disclosure, the target is determined according to a specific application scenario of the distance information, and different application purposes may also enable the target to represent different objects, for example, energy saving control of the electronic device is implemented by obtaining the distance information through measurement, and the target represents a user of the electronic device, that is, state control of the electronic device is implemented by detecting the distance information between the user and the electronic device. If the information calculation for certain specific items is realized by the detected distance information, the target may characterize the specific items.
Furthermore, because a specific installation angle exists between the first sensor and the first body plane, the influence of various use angles of the electronic device is considered, so that the distance measuring process of the first sensor is more consistent with the distance measuring principle of the first sensor, the obtained distance information is more accurate, and the application of the distance information is facilitated, for example, the related functions of the electronic device are controlled through the distance information, or the presentation and calculation of certain information quantity are realized through the distance information.
In another embodiment of the present application, there is provided another electronic device, which, referring to fig. 2, includes a second sensor 20 in addition to a first body 10, a first sensor 11, wherein,
a second sensor 20 for obtaining the target.
The particular mounting of the first sensor 11 to the plane of the first body 10 is present at this point in time such that the light pulse angle of the first sensor 11 is at an angular value within the acquisition angular range of the second sensor 20.
In order to obtain the distance information between the target and the electronic device more accurately, a second sensor 20, which may be a camera, is provided in the electronic device to identify the target. Further, the object recognized by the second sensor 20 may be notified to the first sensor 11, so that the first sensor 11 performs distance detection of the object. When the second sensor 20 is present, in order to ensure that the first sensor 11 can acquire a target within a specific range, it is necessary that the ranging acquisition light beam of the first sensor 11 can fall completely within the range of the second sensor 20, that is, the light pulse angle of the first sensor 11 is within the acquisition angle range of the second sensor 20 in the target area.
The light pulse angle of the first sensor 11 may not be completely within the collection angle range of the second sensor 20, but only the light pulse angle of the first sensor 11 is ensured to be within the collection angle range of the second sensor 20 in the target area, and at this time, the relevant distance information of the target can be accurately obtained through the first sensor 11. The target area may represent an area where the target can be completely measured by the first sensor, that is, an area range matched with the target to be measured, and the area range corresponding to the target area may be determined according to the position of the target and the current use angle of the electronic device, or according to the related settings of the electronic device by the user. It should be noted that the specific installation angle range determined when the light pulse angle of the first sensor 11 is completely within the collection angle range of the second sensor 20 is an optimal choice, and especially for a movable or position-changing target, more accurate ranging results can be obtained.
If the electronic device is a notebook computer having two bodies, the second sensor 20 is a camera, the first sensor 11 is a TOF sensor, and the angle range of the camera is found to be 60 degrees based on the measurement of a general camera, and the light pulse angle of the first sensor is 23 degrees due to the specific installation angle of the first sensor and the plane of the first body, see fig. 3, which respectively shows that when the angle between the first body representing the display screen of the notebook computer and the second body representing the keyboard of the notebook computer is 90 degrees and 120 degrees, the light pulse angle of the first sensor just falls within the collection angle range of the second sensor.
On the basis of the above embodiment, if it is to be ensured that the light pulse angle of the first sensor is exactly within the collection angle range of the second sensor, and the current first sensor is a TOF sensor, and the angle between the first body and the second body is measured from 90 degrees to 135 degrees, the angle value of the specific installation angle can be selected from 9 degrees to 11 degrees.
On the basis of the above embodiment, the electronic device may further include a processor, where the processor is connected to the first sensor and the second sensor, and is configured to control the electronic device to switch from the first state to the second state according to the distance information collected by the first sensor, and power consumption of the first state is smaller than power consumption of the second state.
In the embodiment, the energy-saving control of the electronic equipment is realized by utilizing the distance information acquired by the first sensor. The target in this case may be a user of the electronic device, or may be an identifier characterizing the user of the electronic device, for example, a work card worn by the user. The second sensor recognizes that the target is located near the electronic device, the first sensor detects and obtains the distance information between the target and the electronic device, the distance threshold value of state switching of the electronic device is set, and the processor judges the distance information obtained through current detection to be within the range of the distance threshold value, so that state switching of the electronic device is controlled. The electronic device in use is usually switched from a first state to a second state, i.e. from a high power consumption state to a low power consumption state, for example, the first state is a use state, and the second state may be a standby state, a shutdown state or a state of automatically shutting down high power consumption software.
Therefore, the state switching of the electronic equipment can be accurately controlled through the distance information, the inaccurate measured distance information cannot be caused due to the fact that the user uses different angles of the electronic equipment or the different opening and closing angles of the electronic equipment, and the state switching of the unnecessary electronic equipment is triggered, so that the phenomenon that the user only adjusts the angle of a display screen of a notebook computer to shut down the electronic equipment is avoided.
It should be noted that, when the second sensor exists and the corresponding function is realized by the camera on the existing electronic device, in order to make the layout of the electronic device reasonable and further improve the detection accuracy of the first sensor, it is preferable that the first sensor and the second sensor are disposed in the same region and are disposed in parallel, for example, both the first sensor and the second sensor are disposed in the printing region above the notebook display screen.
In another embodiment of the present invention, the application of 3D modeling is implemented by an existing electronic device, which requires that at least two first sensors are included in the electronic device to form a corresponding information acquisition module, that is:
the first sensors include at least 2 first sensors at different locations, where the processor of the electronic device is further configured to:
and generating three-dimensional information corresponding to the target according to the distance information between the target and the electronic equipment, which is acquired by at least 2 first sensors.
Referring to fig. 4, a schematic structural diagram of an electronic device for measuring three-dimensional information provided in an embodiment of the present application is shown, the electronic device includes a first body 40, a second body 41, and three first sensors, which correspond to numbers 421, 422, and 423, respectively, two first sensors are disposed on the second body, another first sensor is disposed on the first body, and the first sensors are TOF sensors, where the TOF sensors emit modulated near-infrared light, reflect the modulated near-infrared light when encountering an object, and convert a distance of a photographed target by calculating a light emission and reflection time difference or a phase difference to generate depth information.
Through the arrangement of the three first sensors, the detection angle formed by the three first sensors can meet a specific range, such as 90 degrees, so that when the electronic equipment has a certain opening and closing angle, the first sensors on the first body and the second body can detect a crossed area to form a matrix for emitting laser, and after an object is placed in front of the electronic equipment, distance information collection can be performed on the object based on the three first sensors, so that three-dimensional information of the object can be generated according to the collected distance information. In order to improve the 3D modeling precision, the object can perform rotary ranging or measure multiple angles by appropriately moving the position of the electronic equipment according to corresponding instructions.
Therefore, the distance information of the target can be acquired by utilizing the at least two first sensors at different positions on the electronic equipment, and the 3D modeling is carried out by utilizing the distance information, namely, the 3D imaging or information acquisition is realized by utilizing the existing electronic equipment, and the problems that the 3D equipment is too expensive, the size is too large and the like in the prior art are solved.
For example, when the electronic device using the three-dimensional information measurement is used for gesture recognition, the three first sensors may be used to collect distance information from a hand of a user to the electronic device, so as to generate three-dimensional information about the hand of the user, and further, three-dimensional modeling may be performed through the collected three-dimensional information, and an action of the hand of the user may be determined, so as to realize gesture recognition of the user, and then, the electronic device may be controlled according to the recognized gesture action of the user, because the first sensors are used to measure a distance of the hand of the user, so as to establish a three-dimensional model of the hand of the user, compared with image recognition, gesture recognition of the user may be performed more accurately, so as to achieve accurate control of the electronic device through different gestures of the user, for example, the gesture recognition process may be applied to three-dimensional drawing, and the three-dimensional image may be adjusted through the gesture, the method can also be applied to motion sensing games, and based on accurate gesture control, the experience effect of the user is improved.
In another embodiment of the present application, in order to improve the experience effect of the user applying the electronic device, the first sensor disposed on the first body of the electronic device is further configured to:
and continuously acquiring the distance information between the target and the electronic equipment until the electronic equipment reaches the target state.
By setting the target state of the electronic device, the target state may be the state of the electronic device itself, or may correspond to the target state of some application software in the electronic device. For example, the target state may be an operating state or a pause state of video playing software.
Before the electronic device does not reach the target state, the first sensor continuously acquires the distance information between the target and the electronic device, namely the distance information acquired by the first sensor represents an information set, namely the distance information can be acquired correspondingly to the moving target, and different distance information is acquired correspondingly at different moments. And more accurate reference information can be provided when the subsequent application distance information is correspondingly controlled.
On the basis of the foregoing embodiment, the processor of the electronic device is further configured to:
and matching the corresponding trigger modes based on the distance information, so that the trigger time for the electronic equipment to reach the target state is different.
When the distance information is acquired corresponding to the moving target, the acquired distance information includes a plurality of pieces of distance information corresponding to the target at different time or different positions, so that the processor of the electronic device can set a plurality of trigger modes for matching the distance information of different distance intervals, and different control modes can be executed based on different trigger modes, so that the trigger time for the electronic device to reach the target state is different finally.
For example, if the trigger mode corresponds to a mode in which the electronic device is switched from the standby state to the operating state, the distance information collected by the first sensor may be divided into different distance classes according to different distances from the user to the electronic device, and different state wake-up times are set for each class. Therefore, different state wake-up times correspond to different trigger times, and when a user walks to the electronic equipment from different places away from the electronic equipment, the user can switch the electronic equipment to a working state when walking to the use position of the electronic equipment. And interference that is not caused by movement of the electronic device corresponding to the user's location may be excluded.
Correspondingly, further realize accurate control, can gather the relative electronic equipment's in the different position of user distance information to can set for according to user's use gesture, for example stand the gesture, sit, can be for the state of lying when corresponding electronic equipment is the cell-phone, through gathering the different gestures of user, the relative electronic equipment's in different positions distance information, thereby set up the more accurate trigger mode that corresponds, be used for promoting user's experience effect.
Specifically, when the first sensor collects distance information of the user, three detection ranges may be set, that is, the detection ranges correspond to a short distance, a medium distance and a long distance from the electronic device, respectively, for example, the distance between the user and the electronic device is set to be a short distance of 20-40cm, the distance between the user and the electronic device is set to be a medium distance of 40-60cm, the distance between the user and the electronic device is set to be a long distance of 60-120cm, when the first sensor detects that the distance between the user and the electronic device is 60-120cm, the user is likely to pass in front of the electronic device when moving in the distance interval, and is not actually going to use the electronic device, and the corresponding trigger mode is to set a delay in the trigger time, for example, 1 second later, and then a switching instruction of the state of the electronic device is issued. Correspondingly, the delay time can be set to be accurately controlled, further judgment can be carried out according to the user information collected by the first sensor within the delay time, for example, the number of the distance data of the user is detected within the delay time, if only the limited number of the distance data are detected, the state that the electronic equipment is not switched can be further set, and if a plurality of distance data are detected and the distance data are in a descending state, the electronic equipment can be immediately switched to the target state.
Correspondingly, when the first sensor detects that the distance between the user and the electronic equipment is the distance interval of 40-60cm for the first time, the probability that the user sits in front of the electronic equipment is judged to be the largest, the target state awakening time in the corresponding trigger mode is the fastest, and the target state of the electronic equipment can be immediately awakened when the distance information is detected.
It should be noted that the setting of the trigger mode is described according to the function of the electronic device and the user requirement, and is not a unique mode, and the distance information between the user and the electronic device may also be obtained based on the detection of the first sensor, and then the step movement frequency of the user is determined.
The display screen of traditional electronic equipment adopts liquid crystal display alone more, but along with the user improves to electronic equipment's demand, in order to avoid the dust to influence or to liquid crystal display's protection, take notebook computer as an example, most notebook computers all have the glass apron that has protect function now, cover one deck tempered glass on the display screen promptly, this layer of glass can generally be with screen frame level. For electronic devices with glass covers, the first sensor is typically placed over the screen of the electronic device in the printed area of the screen for proper layout. The parameters of the glass cover plate may affect the distance acquisition accuracy of the first sensor at this time.
Therefore, on the basis of the above embodiment, an electronic device provided in another embodiment of the present application further includes:
and the glass cover plate covers the first sensor and has preset light transmission parameters.
The preset light transmission parameters enable the energy ratio of the emission energy and the receiving energy obtained by the first sensor based on the glass cover plate to reach a specific range.
Because the light transmission parameters of the glass cover plate can influence the acquisition precision of the first sensor, the light pulse sent by the first sensor and the energy of the received light returned by the target can completely meet the distance measurement requirement of the first sensor by adopting the preset light transmission parameters.
Specifically, the preset light transmission parameter needs to be determined according to the performance of the glass cover plate and the distance measurement requirement of the first sensor, and how to realize the light transmission parameter is not specifically limited in the embodiment of the application, for example, a glass material meeting the preset light transmission parameter can be adopted as the glass cover plate, and a preset spraying process can be adopted to enable the light transmission parameter of the glass cover plate covering the area of the first sensor to reach the preset requirement.
On the basis of the embodiment, if the first sensor is arranged in the printing area of the electronic screen, the spraying process of the glass cover plate is needed to meet the requirement.
In another aspect of the above embodiment, the glass cover plate adopts a preset spraying process corresponding to a target area of the first sensor, wherein the target area reaches a preset light transmission parameter based on the preset spraying process, and the first sensor obtains a light transmittance reaching a specific range based on the preset light transmission parameter.
The target area is a coverage area on the glass cover plate matched with the first sensor, and the size of the target area can just cover the first sensor or can be an area size determined according to the first sensor. When the preset light transmission parameter is reached through the spraying process, the spraying process in the prior art cannot meet the printing instruction of the target area corresponding to the first sensor, so that the energy of the light transmittance and the reflectivity of the first sensor is influenced, and the detected distance is inaccurate.
Therefore, in the embodiment of the present application, a preset spraying process is provided, and since the preset spraying process needs to make the ratio of the transmitted energy obtained by the first sensor to the received energy reach a specific range, it is difficult to control the spraying process according to the energy ratio in the actual spraying process, and the operability is also poor, in the embodiment of the present application, the spraying process of the glass cover plate is controlled by monitoring the related control condition of the light transmittance.
Specifically, taking the first sensor as a TOF sensor for example, the TOF sensor is installed between a glass cover plate and a housing above a display screen of the notebook computer, the position of the glass cover plate relative to the TOF sensor belongs to a non-display area, and black or other colored ink needs to be sprayed for shielding in general. And the TOF sensor position and the requirement that the sensor can be covered by ink jet, namely the sensor is hidden in the sensor closed state, and meanwhile, certain energy requirements of light pulses sent by the sensor working waveband and light pulses reflected from an object need to be met. Multiple tests show that when the requirements of the conditions are met, the TOF sensor needs to meet the 550nm wave band at the corresponding position, and the spraying control of the light transmittance under the condition of 8% -13% can realize the accurate measurement of the TOF sensor on the distance.
It should be noted that in this example, the spraying process is controlled at the wavelength band of 550nm, so that when the light transmittance reaches 8% to 13%, the spraying process on the current target area is stopped, and if the light wavelength bands are different, the light transmittance can be adjusted correspondingly, so that the final spraying effect of the glass cover plate meets the preset requirement. Therefore, the spraying process of the glass cover plate is controlled by monitoring the light transmittance of the light, and the operation and the control are easier in process.
On the basis of the above embodiment, the electronic apparatus further includes:
and the touch unit is connected with the first sensor and used for receiving the trigger instruction so that the working state of the first sensor is matched with the trigger instruction.
By setting a trigger instruction, the working state of the first sensor can be controlled, namely, the first sensor is enabled to work in a mode that a user needs to carry out distance acquisition. Therefore, the method can be associated with the application scene of the user, the use requirement of the user is met, and the experience effect of the user is improved. For example, when a user participates in a conference, the user needs to leave his own position at variable time to perform corresponding sharing or information explanation, and at this time, the user can set a trigger instruction for turning off the first sensor through the trigger unit, that is, the first sensor does not acquire distance information between the user and the electronic device, so that the phenomenon of unnecessary shutdown caused by the fact that the first sensor detects that the user is far away from the electronic device when working can be avoided. For another example, when the electronic device is used for collecting 3D information of an article, the first sensor can be operated through the trigger unit after the user places the article, so that collection of some interference information can be avoided.
The triggering unit may be implemented by a key connected to the first sensor, the key may be an independent case, or may be combined with other functional keys on the electronic device, for example, for an electronic device with a keyboard, the triggering unit may be any key on the keyboard, or may be a power-on key of the electronic device, and the triggering of the triggering unit is performed by a triggering method different from the original key function by a user, such as a double-click of a letter a in the keyboard. The triggering unit can also be an information acquisition unit, and is realized by acquiring a triggering instruction corresponding to a user, for example, the triggering instruction can be a voice acquisition unit, the corresponding user triggering instruction can be 'start ranging', and can also be a camera of the electronic device, and the corresponding user triggering instruction can be a gesture instruction, so that the user controls the working state of the first sensor through the gesture instruction.
In the embodiment of the application, the first sensor is used for realizing the ranging function, so that the distance information between the user and the specific article and the electronic device can be measured, and the processor can realize different functions according to the obtained distance information, such as control over the electronic device, reuse of information and the like. The electronic equipment can be any one of a smart phone, a tablet computer, a notebook computer and an electronic book device.
The installation angle of the first sensor meets a specific installation angle, when the electronic equipment is a smart phone, the first sensor can be arranged at a position adjacent to a rear camera of the smart phone, and the shooting function of the rear camera is assisted through the distance between an object measured by the first sensor and the smart phone, so that the shooting effect of the smart phone can better meet the requirements of users; when the electronic equipment is an electronic book, the brightness of the screen of the electronic book can be controlled by detecting the distance information between the user and the electronic book, so that the brightness of the screen of the electronic book can always reach the eye protection mode.
In another embodiment of the present application, there is also provided an information acquisition method, including:
s101, acquiring distance information between the target and the electronic equipment based on the acquisition of a first sensor on the electronic equipment.
The first sensor is arranged on a first body of the electronic equipment, and a specific installation angle exists between the first sensor and the plane of the first body, and the specific installation angle is an angle enabling the first sensor to collect distance information between a target and the electronic equipment within a specific range.
On the basis of the above embodiment, in another embodiment of the present application, there is provided an information control method, referring to fig. 5, including:
