Image processing method, image processing device, electronic device, and storage medium

A non-transitory computer-readable storage medium, wherein:

• the computer-readable storage medium is configured to store a program;
• and
• when the program is executed, a device where the computer-readable storage medium is located is controlled to:
• perform key point detection on an image to-be-processed, to determine a plurality of key points in the image to-be-processed, wherein the plurality of key points are corner points in the image to-be-processed;
• determine at least one key point combination among the plurality of key points, wherein each of the at least one key point combination includes four key points and the four key points are used to define a quadrilateral object;
• in response to a key point combination selection instruction input by a user, determine a target key point combination in the at least one key point combination;
• and
• perform perspective distortion correction on a quadrilateral area defined by a quadrilateral object corresponding to the target key point combination on the image to-be-processed, to obtain a processed image.
