Optionally, the number of the marker positions determined by the dynamic scene is greater than the number of the marker positions determined by the static scene, so that the offset degrees of different parts of the shot object can be comprehensively evaluated; the number of the marking point positions determined by the low-brightness scene is larger than that of the marking point positions determined by the high-brightness scene, so that enough data can be provided for analysis when the light is insufficient, and the accuracy is improved; when the type of the shooting object is a person, the marking point position selects preset points in skeleton structure positions, such as the vertex, the elbow, the knee and the like, so that the position information of the marking point position can be more accurately captured.

Optionally, the number of captured images may also be determined depending on the shooting scene. Optionally, the number of images acquired by the dynamic scene is greater than that of images acquired by the static scene, and optionally, the number of images acquired by the dynamic scene is greater than or equal to twice that of images acquired by the static scene, so that for scenes such as the dynamic scene in which the motion of the photographic object is relatively complex, reasonable image analysis can be selectively performed based on more images, for example, the previous frames of images can be analyzed first, whether the next frames of images are analyzed or not is determined according to the analysis result, the calculation amount is reduced, and the situation that the ideal picture cannot be captured due to the fact that the time interval between the acquisition of the images in different batches is too long can be avoided.

Through the process, the number of the collected images and the positions and/or the numbers of the mark point positions can be selected in a targeted manner according to the type and/or the shooting scene of the shooting object, and the reasonability and the calculation accuracy of the calculated amount can be considered when the deviation degree of the shooting object in the front frame image and the back frame image is calculated.

Optionally, step S2, includes:

identifying the mark features in each frame of image;

Optionally, according to the mark features identified in the preview image, the corresponding mark features in each frame of image are identified in the captured image, and according to the rule for determining the mark point positions in the preview image, the mark point position corresponding to each mark feature in each frame of image is determined in the captured image. Then, the degree of deviation between the positions of the corresponding mark points in the previous and subsequent frame images, for example, the degree of deviation between the vertex positions in the two frame images, and the degree of deviation between the positions of the glasses in the two frame images, is calculated, and the data of the degree of deviation corresponding to each frame image corresponds to the number of the mark point positions in each frame image. Alternatively, the maximum value of the degree of shift between the mark point positions of the preceding and following frame images is selected as the degree of shift between the subjects of the preceding and following frame images, for example, the degree of shift between the parietal positions in the two frame images is larger than the degree of shift between the eyeglass positions in the two frame images, and the degree of shift between the parietal positions is selected as the degree of shift between the subjects of the preceding and following frame images, so that the screened images can be made clearer. Alternatively, an average value of the degrees of deviation between the mark point positions of the previous and subsequent frame images may be selected as the degree of deviation between the photographic subjects of the previous and subsequent frame images, thereby increasing the screening rate of the images under appropriate definition requirements. Optionally, the maximum value and the average value of the shift degrees between the mark point positions of the previous and next frame images may be simultaneously selected as the shift degree between the shooting objects of the previous and next frame images, so that the definition requirement and the image screening rate can be considered at the same time.

Optionally, calculating the degree of offset between the positions of the corresponding mark points in the previous and next frame images includes:

Fig. 4 is a schematic diagram showing the degree of shift of the marker point position in the photographing method shown according to the first embodiment.

Optionally, step S2, includes:

Optionally, the mark point positions are used for representing positions of the shot objects, a maximum value and/or an average value of offset distances between the mark point positions of the previous and next frame images may be selected as the offset distances between the shot objects of the previous and next frame images, and a ratio between the offset distance between the shot objects of the previous and next frame images and the acquisition time interval of the previous and next frame images is calculated to obtain the offset degree between the shot objects of the previous and next frame images.

Optionally, step S2, further includes:

Optionally, the meeting of the preset condition includes that the degree of deviation between the photographic subjects of the previous and next frame images is less than or equal to a preset threshold, and optionally, the preset threshold is 10 pxl/s. Alternatively, when the maximum value and/or the average value is selected as described above, it is only necessary that any one of the maximum value and/or the average value is less than or equal to the preset threshold value, and the preset condition can be considered to be met.

Optionally, at least one frame of image is selected from all the shot images to be output as a clear image, or at least one frame of image is selected from analyzed images to be output as a clear image, wherein the number of the analyzed images is less than the total number of the shot images. Alternatively, the first N (N < X) images in the X acquired images may be analyzed, the degree of shift between corresponding mark point positions in the previous and subsequent frame images of the first N images may be calculated, whether the degree of shift between the objects of the previous and subsequent frame images meets a preset condition may be detected, if the preset condition is met, at least one frame image may be selected from the previous N images to be output as a clear image, the remaining images may not be analyzed and deleted, if the preset condition is not met, the subsequent M (N + M ═ X) images may be continuously analyzed, the degree of shift between corresponding mark point positions in the previous and subsequent frame images may be calculated, whether the degree of shift between the objects of the previous and subsequent frame images meets the preset condition may be detected, if the preset condition is met, at least one frame image may be selected from the subsequent M images to be output as a clear image, if the degree of shift between the objects of the previous and subsequent frame images in the subsequent M images does not meet the preset condition, the degrees of displacement between the photographic subjects of the front and rear frame images in all the X images may be sorted, and at least one frame image may be selected as a clear image to be output based on the sorting result. Therefore, by acquiring more images at one time and analyzing the images in batches, the calculated amount can be reduced when the jitter is small, and the situation that the ideal picture cannot be captured due to overlong image acquisition time intervals of different batches can be avoided.

Optionally, step S22, includes:

For example, the user may be prompted to keep the picture for 3 seconds, within 3 seconds, a preset number of images may be collected first for analysis, if the analysis result does not meet the preset condition, the images may be collected again for analysis, and in the process of keeping the picture, the position difference of the shot object between different batches of images may be reduced, and the analysis accuracy may be improved.

Optionally, when the offset degree between the shot objects of any previous and subsequent frame images in the image collected this time does not meet the preset condition, the offset degree between the shot objects of the previous and subsequent frame images in at least two frame images collected this time can be sorted, and based on the sorting result, at least one frame image is selected as a clear image to be output without being collected, so that the method is suitable for a dynamic scene.
