Fig. 1 schematically illustrates an application scenario 100 of the image acquisition method of the embodiment of the present disclosure.

As shown in fig. 1, an application scenario 100 according to an embodiment of the present disclosure may include an electronic device 110 and a pan-tilt 120.

According to an embodiment of the present disclosure, the electronic device 110 may include an image acquisition apparatus. For example, the electronic device 110 may be a camera including a camera, a smartphone, a tablet computer, and so forth.

In the disclosed embodiment, the image capture device of electronic device 110 may be used to capture images that include user 130.

According to the embodiment of the present disclosure, the holder 120 may be used to change the operating parameters of the image capturing device of the electronic device 110.

For example, the electronic device 110 may be removably connected to the pan/tilt head 120. For example, the cradle head 120 may be disposed outside the electronic device 110 for fixing the electronic device 110. The electronic device 110 may be used to control the spatial layout (attitude) of the pan/tilt head 120. For example, the electronic device 110 may send a control signal to the holder 120 to control the holder 120 to change the posture of the three degrees of freedom, so as to drive the electronic device 110 to change the posture, and to adjust the operating parameters of the image capturing apparatus of the electronic device 110.

For another example, the cradle head 120 may be disposed inside the electronic device 110. For example, the pan/tilt head 120 may be directly connected to the image capture device inside the electronic device. The electronic device 110 can control the holder 120 to change the posture of the internal image capturing device while keeping itself still, thereby adjusting the operating parameters of the image capturing device of the electronic device 110.

According to the embodiment of the disclosure, the first image containing the user 130 may be acquired by the image acquisition device of the electronic device 110. The processor of the electronic device 110 may identify the pose of the user 130 in the captured first image and determine the operating parameters of the image capture apparatus based on the pose of the user 130. Then, the pan/tilt head 120 is controlled to change the attitude in three degrees of freedom to adjust the operating parameters of the image capturing apparatus. The image capturing device can capture the second image according to the adjusted working parameters, so that the purpose that the directly obtained second image can meet the requirement of the user 130 can be achieved. The image acquisition method provided by the embodiment of the disclosure is convenient to operate, can directly capture the image meeting the needs of the user, avoids the problem that the pose of the target object needs to be adjusted for many times during shooting in the related technology, or the complicated process of shooting the stored image first and then adjusting the image is needed, and improves the user experience.

It should be noted that fig. 1 is only an example of an application scenario in which the image acquisition method of the embodiment of the present disclosure may be applied to help a person skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiment of the present disclosure may not be applied to other devices, systems, environments or scenarios.

Fig. 2 schematically shows a flowchart of an image acquisition method of an embodiment of the present disclosure.

As shown in fig. 2, the method includes operations S201 to S204.

In operation S201, a first image is acquired.

According to the embodiment of the present disclosure, acquiring the first image may be, for example, acquiring the first image by an image acquisition device of the electronic device. For example, the first image may be acquired by an image sensor of the camera.

In the embodiment of the present disclosure, acquiring the first image may be, for example, turning on an image sensor and acquiring an image, and the process may not perform an image saving operation. Acquiring the first image may also be acquiring a pre-stored first image. The first image may be a real scene, or a scene virtualized by artificial intelligence or the like.

According to the embodiment of the disclosure, in response to receiving a starting instruction of a user, the image acquisition device of the electronic equipment is switched to a working state, and the acquired image is acquired and displayed so that the user can preview the image.

In the embodiment of the present disclosure, the acquired first image may be identified, whether the first image includes the target object may be determined, and in the case where the first image does not include the target object, the operation may be paused or terminated, or a prompt message may be output. For example, whether or not a person is included in the acquired image may be recognized, and if not, prompt information may be output. The prompt information may be used to prompt the user that no image of the user can be obtained in the current viewing range, and ask the user to move to the current viewing range. If the first image contains a person, the subsequent operation can be continuously executed.

In operation S202, a pose of the target object in the first image is identified.

According to an embodiment of the present disclosure, the target object may be, for example, a person. For example, when a person is recognized in the first image, the recognized person is the target object. For another example, when a plurality of persons are recognized in the first image, a person satisfying the condition may be selected as the target object. The satisfaction condition may be, for example, a person selected by the person for the user, or a proportion satisfaction condition of the person, or the like.

In an embodiment of the present disclosure, identifying the pose of the target object in the first image may be identifying the pose of the shoulder of the person in the first image. For example, the inclination angle between the shoulder reference line of the person and the preset reference line may be identified. For example, a head-shoulder level detection algorithm may be executed by an ISP (Image Signal Processing) chip to identify the inclination angle of the shoulder reference line with respect to the horizontal line of the Image sensor. It is understood that the embodiment of the present disclosure does not limit the algorithm of the shoulder reference line, and the setting may be performed by a person skilled in the art according to practical situations, for example, the shoulder reference line may be a connecting line between the highest points of the shoulders on both sides, and the like.

In another embodiment of the present disclosure, identifying the pose of the target object in the first image may also be identifying the position of the head and shoulders of the person in the first image. For example, the offset distance of the head and shoulders of the person with respect to the center position of the image may be identified. For example, the head and shoulder detection algorithm may be run by the ISP chip to detect the position of the head and shoulder in the image viewing range. It is understood that the embodiments of the present disclosure do not limit the specific algorithm for head and shoulder detection, and those skilled in the art can set the algorithm according to actual situations, for example, the position of the shoulder can be directly determined by detecting the position of the head, and the like.

In yet another embodiment of the present disclosure, identifying the pose of the target object in the first image may also be identifying a ratio between the size of the person in the first image and the size of the first image. For example, the ratio between the area occupied by a person and the area of an image may be identified. Alternatively, the ratio between the width/height of the person and the width/height of the image may also be identified.

The embodiment of the disclosure can identify whether the pose of the user in the first image meets the requirement of the certificate photo through the method described above or other methods.

In operation S203, the working parameters when the second image is acquired are adjusted based on the pose of the target object in the first image.

According to the embodiment of the disclosure, the working parameters of the image acquisition device can be adjusted based on the pose of the target object in the first image. For example, internal and/or external parameters of the image capture device may be adjusted. For example, the pose of the image acquisition device in three degrees of freedom may be adjusted. Or the focal length, exposure time, etc. of the image acquisition device may be adjusted.

In an embodiment of the present disclosure, the working parameters of the image capturing device when capturing the second image may be adjusted based on the posture of the shoulder of the person in the first image, so that the shoulder reference line of the person in the second image is parallel to the preset reference line.

For example, as shown in FIG. 3A, the image capture device 330 may capture the first image 310 at the original operating parameters. It is recognized that there is an inclination angle between the shoulder reference line L1 of the person in the first image 310 and the horizontal line L2 of the image capturing apparatus 330. The image capturing device 330 may be controlled to rotate by a first angle with respect to the z-axis based on the tilt angle so that the shoulder reference line L1 of the person in the second image 320 captured by the image capturing device 330 after the adjustment is parallel to the horizontal line L2 of the image capturing device 330.

In another embodiment of the present disclosure, the operating parameters of the image capturing device when capturing the second image may be adjusted based on the position of the head and shoulders of the person in the first image, such that the head and shoulders of the person in the second image are located in the center region of the second image.

For example, as shown in FIG. 3B, the image capture device 330 may capture the first image 330 at the original operating parameters. The offset distance of the person's head and shoulders in the first image 330 relative to the image center position is identified. The image capture device 330 may be controlled to rotate a second angle with respect to the x-axis and a third angle with respect to the y-axis based on the offset distance such that the head and shoulders of the person in the second image 340 captured by the adjusted image capture device 330 are located within the central region of the image.

In still another embodiment of the present disclosure, the operation parameter when the image capturing apparatus captures the second image may be adjusted based on a ratio between a size of a person in the first image and a size of the first image so that the ratio between the size of the person in the image at the time of capturing the second image and the size of the second image satisfies a threshold.

For example, as shown in FIG. 3C, the image capture device 330 may capture a first image 350 at the original operating parameters. A ratio between the area of the person in the first image 350 and the area of the first image is identified. The field angle of the image capturing device 330 may be adjusted based on the ratio, for example, the adjustment of the field angle of the image capturing device 330 may be achieved by changing the focal length of the image capturing device 330. So that the ratio between the area of the person in the second image 330 acquired by the adjusted image acquisition device 330 and the area of the second image satisfies the threshold. It is understood that the threshold of the embodiment of the present disclosure may be, for example, a threshold range, and the ratio between the area of the person in the second image 330 acquired by the adjusted image acquisition device and the area of the second image should be higher than the lowest threshold and lower than the highest threshold.

The embodiment of the present disclosure does not limit the adjustment sequence of each operating parameter of the image capturing device, and those skilled in the art can set the adjustment sequence according to actual needs. For example, the working parameter corresponding to the threshold value may be adjusted to make the ratio between the size of the person in the second image and the size of the second image satisfy, the working parameter to make the head and the shoulder of the person in the second image located in the central area of the second image may be adjusted, and the working parameter to make the shoulder reference line of the person in the second image parallel to the preset reference line may be adjusted.

According to the embodiment of the present disclosure, the adjusting of the operating parameter when the second image is acquired may be further performing stretching processing on the acquired second image by the image acquisition device to scale up or down the original image. Alternatively, the acquired second image may be distorted to adjust for the proportion of the original image that is distorted proportionally, e.g., when the user's shoulders are not balanced or symmetrical, the distortion may be adjusted. Alternatively, the acquired second image may also be subjected to a cropping process to crop a portion of the original image, or the like.

In operation S204, a second image is acquired with the adjusted working parameters, so that the pose of the target object in the second image satisfies a preset condition.

According to an embodiment of the present disclosure, the second image may be captured with the adjusted operating parameter in response to a user instruction. The user instructions may include at least one of user operation instructions, user voice instructions, or user behavior instructions. For example, the user may control the image acquisition device to capture the second image through a key. Alternatively, the user may control the image capturing device to capture the second image by issuing a voice instruction of "take a picture". Alternatively, the user may control the image capturing device to capture the second image through a specific gesture.

According to the embodiment of the present disclosure, the second image may also be acquired with the adjusted operating parameter in response to the acquisition condition being satisfied. The satisfying of the acquisition condition may include at least one of satisfying a preset duration or the pose of the target object in the second image having satisfied the preset condition. For example, a duration from the current time to the target object entering the shooting mode may be detected, and if the duration reaches a duration threshold, the image acquisition device may be controlled to capture the second image. Alternatively, it may be detected whether the pose of the person in the image acquired by the image acquisition device has met the requirements of the identification photo, and if so, the image acquisition device may be controlled to capture the second image.

In the embodiment of the present disclosure, the acquired second image may also be processed.

In an embodiment of the present disclosure, the face of the person in the second image may be processed. For example, the face of the person in the second image is treated with buffing, whitening, spot removal, acne removal, face thinning, or highlighting.

In another embodiment of the present disclosure, the rendering process may be further performed on the background in the second image. For example, the background in the second image, excluding the person, is rendered based on a background color selected by the user or determined from the identification photograph scene or default. Alternatively, the second image is rendered based on a filter selected by the user or determined from the identification photo scene or by default.

In still another embodiment of the present disclosure, the inclination angle of the head of the person in the second image with respect to the shoulder may also be corrected. For example, an angle between a line of symmetry of the head of the person and a reference line of the shoulder is determined, and the pose of the head is adjusted based on the angle to correct the inclination angle of the head with respect to the shoulder.

For example, as shown in fig. 3D, it is possible to recognize an angle between the line of symmetry L3 of the head of the person and the reference line L1 of the shoulder, and in the case where the angle exceeds a threshold range (for example, 85 degrees to 95 degrees), the inclination angle of the head with respect to the shoulder is corrected so that the angle between the corrected line of symmetry L3 of the head and the reference line L1 of the shoulder satisfies the threshold range.

According to the embodiment of the disclosure, the second image before processing and the current processing progress can be displayed in the process of processing the second image. For example, a second image acquired in response to a user instruction may be presented, and the current progress of processing the second image may be presented in the form of a floating window. For example, the presentation may be in the form of a progress bar.

According to the embodiment of the present disclosure, in response to completion of processing, the processed image may be stored and the stored image may be displayed.

The embodiment of the disclosure may acquire the image in the acquisition mode in real time by the image acquisition device, but does not perform the storage. For example, a first image may be acquired by the image acquisition device in an acquisition mode, and the operating parameters of the image acquisition device may be adjusted based on the pose of the target object in the first image, and the image acquisition device may then acquire a second image with the adjusted operating parameters, such that the shoulder reference line of the person in the second image may be parallel to the preset reference line, and/or the head and shoulders may be located in a central region, and/or the person size ratio may be eligible. The image acquisition device and the image acquisition method can display the acquired image to the user in a preview mode, and the user can instruct the image acquisition device to shoot and capture the current image according to the preview effect. The embodiment of the disclosure can further process the captured image, for example, correct the head and shoulder inclination angle, and/or make a beautiful look, and/or render a background, etc., and store and display the processed image to the user. Compared with the prior art that the pose of the target object needs to be adjusted for many times to meet the composition requirement, or the target object needs to be shot by the user and then guided into the application program for post-processing, the complicated process of repeated operation of the user is simplified, the user can directly shoot and obtain the desired image, and the user experience is improved.

Fig. 4 schematically shows a flow chart of an image acquisition method according to another embodiment of the present disclosure.

As shown in fig. 4, the method includes operations S401 to S415.

In operation S402, the GUI or APP selects a certificate mode.

According to the embodiment of the present disclosure, the user may perform the operation of mode selection through the GUI or the APP. For example, the shooting mode of the camera may be selected as a certified shooting mode.

In operation S403, the pan/tilt head is rotated to a self-portrait position.

According to the embodiment of the disclosure, when the shooting mode of the camera is switched to the identification photo mode, the cradle head can enter the identification photo shooting mode. For example, the Yaw axis (Yaw axis) of the pan/tilt head may be controlled to rotate 180 ° into a self-portrait state with the viewing range of the camera facing the user.

In operation S404, face recognition and head-shoulder recognition are turned on.

According to the embodiment of the disclosure, the face recognition and head and shoulder detection algorithms can be operated through the ISP chip of the camera, and the positions of the face and the head and shoulder in the view finding range can be detected.

In the embodiment of the present disclosure, if a face is not detected, the user may be prompted on a GUI or APP. For example, the "identification photo mode needs to place the face in the viewing range" and other prompting contents. In the embodiment of the disclosure, if the movement of the face or the head and the shoulder is detected, the holder can be controlled to adjust and track the face or the head and the shoulder, so that the face and the head and the shoulder are kept in the view finding range.

In operation S405, the face and shoulder ROI regions are locked.

And then sending an instruction to the tripod head to inform an MCU (Microcontroller Unit) of the tripod head to drive a motor to control a Yaw axis (Yaw), a Roll axis (Roll) and a Pitch axis (Pitch) to adjust the posture, and particularly, controlling the Roll axis (Roll) to eliminate the inclination angle of a shoulder datum line relative to the horizontal line of an image sensor of the camera, so that the shoulder datum line is parallel to the horizontal line of the image sensor of the camera, and eliminate the position difference of a head shoulder relative to the central point of a view range, so that the head shoulder is in the central area of the view range, and thus, the effect that the head shoulder of a person in the acquired image is centered and horizontal is realized. In operation S407, the face is beautified.

According to the embodiment of the disclosure, the face beautifying algorithm can be operated through the ISP chip of the camera, the portrait face beautifying mode is entered, and the treatments of skin grinding, skin beautifying, spot removing, acne removing, highlight and the like are carried out on the face in the acquired image.

In operation S408, the optical zoom or the digital zoom adjusts the viewing range.

According to the embodiment of the disclosure, optical zooming or digital zooming can be performed according to the ratio of the size of the ROI to the size of the viewing range, so that the imaging size of the head and the shoulder meets the requirement of the identification photo.

In operation S409, a background color or a filter is selected.

According to the embodiment of the disclosure, a user can select a desired background color and a filter through GUI or APP according to a previewable real-time certificate photo effect on an LCD of the handheld pan-tilt camera. The background color may include, for example, a background color such as white, blue, or red. The filters may include, for example, borders, rendering or animal morphology filters, and the like.

In operation S410, photographing is started.

According to the embodiment of the present disclosure, photographing may be started in response to the user pressing the shutter key. The ISP chip can acquire the raw image in rggb format from the image sensor, and form a rough certificate photo YUV image after a series of filtering processing and format conversion processing.

In operation S411, a head-shoulder area is cut according to the head-shoulder frame position.

According to the embodiment of the disclosure, the head and the shoulder in the YUV image can be cut out, and the inclination angle of the head relative to the shoulder is eliminated through a head correction algorithm.

Or when the detected inclination angle of the head relative to the shoulder is larger than a certain range, the head of the user is prompted to be incorrect in real time on the LCD, so that the user can move the head position according to the prompt information on the LCD, and the inclination angle of the head relative to the shoulder is eliminated.

In operation S412, the non-head-shoulder area performs background rendering.

According to the embodiment of the present disclosure, the rendering process may be performed on the background area other than the head-shoulder area according to the background color and the filter selected by the user in operation S409.
