Description

一种聚焦成像的装置、方法和终端Device, method and terminal for focusing imaging 技术领域Technical field
本申请涉及但不限于成像技术，尤其涉及一种聚焦成像的装置、方法和终端。The present application relates to, but is not limited to, imaging technology, and more particularly to an apparatus, method and terminal for focused imaging.
背景技术Background technique
便携设备，如移动终端等，在采用单摄像镜头进行成像时，由于单摄像镜头的景深范围为焦点前后2.5m，在该景深范围外的目标图像都会出现失焦，从而导致成像模糊的问题。In a portable device, such as a mobile terminal, when a single camera lens is used for imaging, since the depth of field of the single camera lens is 2.5 m before and after the focus, the target image outside the depth of field will be out of focus, resulting in blurring of the image.
为了解决便携设备的单镜头成像模糊问题，通常会采用主副摄像镜头实现快速聚焦，主摄像镜头用于拍照及图像信息收集，副摄像镜头采用宽景深镜头，用于收集主摄像镜头与拍摄物的距离，将位置信息反馈到图像处理***。但是，由于副摄像镜头通常由光学器材制成，所以在收集主摄像镜头与拍摄物的距离过程中，容易被外界光线所影响，在低光照度的条件下无法测距。In order to solve the single-lens imaging blur problem of portable devices, the main and sub-camera lenses are usually used for fast focusing, the main camera lens is used for photographing and image information collection, and the sub-camera lens uses a wide depth of field lens for collecting the main camera lens and the subject. The distance is fed back to the image processing system. However, since the sub-camera lens is usually made of optical equipment, it is easy to be affected by external light during the distance between the main imaging lens and the subject, and it is impossible to measure distance under low illumination conditions.

实施例一Embodiment 1
参见图1，其示出了本发明实施例提供的一种聚焦成像的装置10，该装置10可以应用于具有拍摄功能的移动终端中，例如智能手机、平板电脑、笔记本电脑等，该装置10可以包括：采集模块101、选取模块102和处理模块103Referring to FIG. 1 , a device 10 for focusing imaging according to an embodiment of the present invention is shown. The device 10 can be applied to a mobile terminal having a photographing function, such as a smart phone, a tablet computer, a notebook computer, etc., and the device 10 The method may include: an acquisition module 101, a selection module 102, and a processing module 103.
所述采集模块101，设置为：接收第一指令以采集图像信息并生成预览图像；其中，所述采集图像信息包括：通过摄像镜头采集物体信息以及通过传感器采集所述物体信息对应的坐标信息；The acquiring module 101 is configured to: receive a first instruction to collect image information and generate a preview image; wherein the collecting image information includes: collecting object information through the camera lens, and collecting coordinate information corresponding to the object information by using a sensor;
所述选取模块102，设置为：接收第二指令以选取所述预览图像中的第一物体信息；The selecting module 102 is configured to: receive a second instruction to select first object information in the preview image;
所述处理模块103，设置为：根据所述选取的第一物体信息和所述第一物体的坐标信息对所述预览图像进行聚焦处理。The processing module 103 is configured to perform focusing processing on the preview image according to the selected first object information and coordinate information of the first object.
可以理解地，本实施例提供的聚焦成像的装置10中，采集模块101通过传感器利用传播波进行景物的测距，并根据传播波的测距对取景预览图像进行聚焦，从而使得聚焦过程不会受到外界光线环境的影响，在低光照度的条件下仍然能够为了对取景预览图像进行聚焦而收集主摄像镜头与拍摄物的距离。It can be understood that, in the apparatus 10 for focusing imaging provided by the embodiment, the acquisition module 101 performs the ranging of the scene by using the propagating wave by the sensor, and focuses the framing preview image according to the ranging of the propagating wave, so that the focusing process does not occur. Under the influence of the external light environment, the distance between the main camera lens and the subject can still be collected in order to focus the framing preview image under low illumination conditions.
示例性地，在图1所示的聚焦成像的装置10中，采集模块101可以包括如图2所示的一个具有自动聚焦及拍摄功能的摄像镜头(简称为摄像头)，可以根据需求选择焦距范围、镜头视场角角度、光圈大小等拍摄参数进行拍摄。当移动终端启动聚焦成像的装置10时，摄像镜头可开启，并可根据预先设置好的拍摄参数在该摄像镜头的取景范围内采集得到取景预览图像，并且，还可以将取景预览图像展示在显示单元中。Illustratively, in the apparatus 10 for focusing imaging shown in FIG. 1, the acquisition module 101 may include an imaging lens (referred to as a camera) having an autofocus and photographing function as shown in FIG. 2, and the focal length range may be selected according to requirements. Shooting parameters such as lens angle of view and aperture size are taken. When the mobile terminal activates the device 10 for focusing imaging, the camera lens can be turned on, and the finder preview image can be acquired within the framing range of the camera lens according to the preset shooting parameters, and the finder preview image can also be displayed on the display. In the unit.
示例性地，在图1所示的聚焦成像的装置10中，采集模块101还可以包括一个传播波测距传感器，比如超声波测距传感器或红外线测距传感器。可以理解地，传播波也可以选择其他形式的传播波。Illustratively, in the focused imaging device 10 shown in FIG. 1, the acquisition module 101 may further include a propagating wave ranging sensor such as an ultrasonic ranging sensor or an infrared ranging sensor. It can be understood that the propagating wave can also select other forms of propagating waves.
对于超声波测距传感器来说，超声波测距传感器所发射的超声波需要满足采集模块101中摄像镜头的取景范围，即摄像镜头的镜头视场角角度。 For the ultrasonic distance measuring sensor, the ultrasonic wave emitted by the ultrasonic distance measuring sensor needs to satisfy the viewing range of the imaging lens in the collecting module 101, that is, the angle of view of the lens of the imaging lens.
可选地，由于超声波是一种纵向振动的弹性机械波，借助于传播介质的分子运动而传播。因此，超声波的波动方程描述与电磁波类似，如式1所示：Alternatively, since the ultrasonic waves are longitudinally vibrating elastic mechanical waves, they propagate by means of molecular motion of the propagation medium. Therefore, the description of the wave equation of the ultrasonic wave is similar to the electromagnetic wave, as shown in Equation 1:
Figure PCTCN2016086903-appb-000001
Figure PCTCN2016086903-appb-000001
其中，A(x)为振幅，A0为常数，w为圆频率，t为时间，x为超声波的传播距离，
Figure PCTCN2016086903-appb-000002
为波数，λ为超声波的波长，超声波的衰减常数α＝af2，其中，a为介质常数，f为超声波的振动频率。Where A(x) is the amplitude, A 0 is a constant, w is the circular frequency, t is the time, and x is the propagation distance of the ultrasonic wave.
Figure PCTCN2016086903-appb-000002
For the wave number, λ is the wavelength of the ultrasonic wave, and the attenuation constant of the ultrasonic wave is α=af 2 , where a is the dielectric constant and f is the vibration frequency of the ultrasonic wave.
例如，空气的介质常数a＝2×10-13s2/cm，因此，当超声波的振动频率为f＝40kHz时，α＝3.2×10-4cm-1，1/α＝31m；当f＝30kHz时，1/α＝56m。由此可以看出，超声波的频率越高，衰减得越厉害，传播的距离也越短。考虑到摄像镜头的焦距范围，可选地，f＝40kHz。For example, the medium constant of air a = 2 × 10 -13 s 2 /cm, therefore, when the vibration frequency of the ultrasonic wave is f = 40 kHz, α = 3.2 × 10 -4 cm -1 , 1 / α = 31 m; At =30 kHz, 1/α = 56 m. It can be seen that the higher the frequency of the ultrasonic wave, the more the attenuation is, and the shorter the distance of propagation. Considering the focal length range of the camera lens, optionally, f = 40 kHz.
另外，超声波测距传感器的指向角θ是超声波波束半功率角的夹角，它能够直接影响测距的分辨率，也是影响测距精度的一个重要技术参数。以圆片超声波测距传感器为例，它的指向角θ大小与圆片超声波测距传感器的超声波的波长λ和圆片超声波测距传感器的半径r有关，两者的关系可如式2所示：In addition, the pointing angle θ of the ultrasonic ranging sensor is the angle of the half power angle of the ultrasonic beam, which can directly affect the resolution of the ranging, and is also an important technical parameter affecting the ranging accuracy. Taking the disk ultrasonic ranging sensor as an example, its pointing angle θ is related to the wavelength λ of the ultrasonic wave of the disk ultrasonic ranging sensor and the radius r of the disk ultrasonic ranging sensor, and the relationship between the two can be as shown in Equation 2. :
Figure PCTCN2016086903-appb-000003
Figure PCTCN2016086903-appb-000003
由式(2)可以得知，超声波测距传感器的指向角θ愈小，空间分辨率愈高，则要求圆片超声波测距传感器的半径r愈大。当f＝40kHz时，可以得到：超声波的波长λ＝C/f＝340/40000＝8.5mm，其中，C表示超声波在空气中的传播速度。此时，根据式(2)所示的超声波测距传感器的指向角θ与圆片超声波测距传感器的半径r和超声波的波长λ之间的对应关系，本实施例中，超声波的振动频率可选地为f＝40kHz。It can be known from the formula (2) that the smaller the pointing angle θ of the ultrasonic distance measuring sensor is, the higher the spatial resolution is, the larger the radius r of the wafer ultrasonic distance measuring sensor is required. When f = 40 kHz, it can be obtained that the wavelength of the ultrasonic wave λ = C / f = 340 / 40000 = 8.5 mm, where C represents the propagation speed of the ultrasonic wave in the air. At this time, according to the correspondence between the directivity angle θ of the ultrasonic distance measuring sensor and the radius r of the ultrasonic wave distance measuring sensor and the wavelength λ of the ultrasonic wave, in the present embodiment, the vibration frequency of the ultrasonic wave can be The ground selection is f=40 kHz.
因此，采集模块101可以利用超声波传感器以根据所述摄像镜头的取景范围通过频率为40千赫兹KHz的超声波采集所述物体信息对应的坐标信息。Therefore, the acquisition module 101 can use the ultrasonic sensor to acquire coordinate information corresponding to the object information by ultrasonic waves having a frequency of 40 kHz KHz according to the framing range of the imaging lens.
对于红外线传感器来说，由于红外线的指向角要远远小于超声波的指向 角，因此，一条红外线光束仅能对单一方向或者单一角度上的物体进行测量，因此，若要采集摄像镜头的取景范围内物体的坐标信息，那么红外线传感器就需要多种红外线进行测量，所以采集模块101可利用红外线传感器以在所述摄像镜头的取景范围内通过同频率而不同发射角度的多条红外线采集所述物体信息对应的坐标信息。For infrared sensors, the pointing angle of the infrared rays is much smaller than the pointing of the ultrasonic waves. Angle, therefore, an infrared beam can only measure objects in a single direction or a single angle. Therefore, if the coordinate information of an object within the viewing range of the camera lens is to be acquired, the infrared sensor needs a variety of infrared rays to measure, so the acquisition is performed. The module 101 can use the infrared sensor to collect coordinate information corresponding to the object information by using a plurality of infrared rays of different emission angles at the same frequency within the viewing range of the imaging lens.
示例性地，在图1所示的聚焦成像的装置10中，可以通过传播波的发射时间与所述传播波回波的接收时间之差获取所述预览图像中的物体与所述采集模块101的摄像镜头之间的距离。Illustratively, in the apparatus 10 for focusing imaging shown in FIG. 1, an object in the preview image and the acquisition module 101 may be acquired by a difference between a transmission time of a propagating wave and a receiving time of the propagating wave echo. The distance between the camera lenses.
可选地，当传播波为超声波时，相应地，预览图像中的物体与所述采集模块101的摄像镜头之间的距离L可以通过式(3)获得：Alternatively, when the propagating wave is an ultrasonic wave, correspondingly, the distance L between the object in the preview image and the imaging lens of the collecting module 101 can be obtained by the formula (3):
Figure PCTCN2016086903-appb-000004
Figure PCTCN2016086903-appb-000004
其中，T为渡越时间，即超声波发射端发出的超声波，经气体介质传播到超声波接收端的时间。可以理解地，如图3所示，当超声波测距传感器采用异地脉冲反射式地测量预览图像中的物体与所述采集模块101的摄像镜头之间的距离时，该距离是声波传输距离的一半。可以理解地，传播波为红外线时，预览图像中的物体与所述采集模块101的摄像镜头之间的距离的获取方式同上，不再赘述。Where T is the transit time, that is, the time when the ultrasonic wave emitted from the ultrasonic transmitting end propagates through the gaseous medium to the ultrasonic receiving end. It can be understood that, as shown in FIG. 3, when the ultrasonic distance measuring sensor measures the distance between the object in the preview image and the imaging lens of the acquisition module 101 by using the off-site pulse reflection, the distance is half of the sound wave transmission distance. . It can be understood that when the propagating wave is infrared, the distance between the object in the preview image and the imaging lens of the collecting module 101 is the same as that of the above, and will not be described again.
示例性地，在图1所示的聚焦成像的装置10中，采集模块101所生成取景预览图像可以通过具有触摸感应的显示单元进行显示，当选取模块102接收到用户对显示的预览图像中的某一物体进行选择的第二指令时，可根据用户的选择指令选取预览图像中的第一物体信息。Illustratively, in the apparatus 10 for focusing imaging shown in FIG. 1, the framing preview image generated by the acquisition module 101 can be displayed by a display unit having touch sensing, when the selection module 102 receives the preview image of the user on the display. When an object selects the second instruction, the first object information in the preview image may be selected according to the user's selection instruction.

可选地，所述目标物体与所述采集模块101的摄像镜头之间的距离和所述选取的第一物体与所述采集模块101的摄像镜头之间的距离相等，因此，目标物体与选取的第一物体处于统一平面，所以聚焦子模块1032能够对处于统一平面的景物进行聚焦处理。Optionally, the distance between the target object and the imaging lens of the acquisition module 101 and the distance between the selected first object and the imaging lens of the acquisition module 101 are equal, and therefore, the target object and the selection The first object is in a uniform plane, so the focusing sub-module 1032 is capable of focusing the scene in a uniform plane.
可选地，统一平面的区域范围也可以通过用户的需求进行设置和确定，因此，该装置10还包括：Optionally, the area range of the unified plane can also be set and determined by the user's needs. Therefore, the device 10 further includes:
