and calculating the bending angle of the terminal screen based on the coordinate information and the ambient light parameter of the shooting target, specifically, acquiring the position of the terminal flash lamp, and calculating the bending angle of the terminal screen based on the coordinate information and the ambient light parameter of the shooting target.

Referring to fig. 4, the step of calculating a bending angle of the terminal screen based on the coordinate information of the shooting target includes:

step S21, acquiring the contour coordinate of the shooting target based on the coordinate information of the shooting target, and acquiring the relative position of the contour coordinate and a terminal screen;

in this embodiment, after identifying the photographic target, the outline of the photographic target is identified, specifically, after identifying the photographic target and acquiring the coordinate information of the photographic target, the contact coordinates of the coordinate information of the photographic target and the photographic background are extracted based on the coordinate information of the photographic target, the outline coordinates of the photographic target are generated based on the respective contact coordinates, and the most edge coordinates of the outline of the photographic target are acquired, it should be noted that the most edge coordinates of the outline of the photographic target in this embodiment include the coordinate positions of different edge areas of the photographic target farthest relative to the flash, and for the specific embodiment, when a person is self-photographed, the coordinate positions of the left and right face outline edges relative to the farthest flash are acquired, respectively, as shown in fig. 5, and the coordinate positions of the upper and lower face outline edges farthest relative to the flash are acquired, wherein, when a plurality of persons are self-photographed, and taking different human faces as an integral shooting target, and respectively obtaining the most edge coordinates of the outline of the integral shooting target.
