Image processing method, image processing device and computer readable storage medium

An image processing device comprising:

• an image capture circuit, configured to obtain an original disparity image;
• a storage circuit, configured to store a plurality of modules;
• and
• a processor coupled to the image capture circuit and the storage circuit, wherein the processor is configured to receive the original disparity image and execute the plurality of modules to implement a plurality of operations, the operations comprising:
• obtaining a background correlation line in a mapping disparity map according to a background region corresponding to a target object;
• and deleting the background region in the original disparity image based on the background correlation line to recognize the target object,
• wherein the operations implemented by the modules executed by the processor further comprise:
• finding the background correlation line in the mapping disparity map;
• obtaining an estimated background disparity map based on the background correlation line;
• and comparing the estimated background disparity map and the original disparity image, and deleting the background region in the original disparity image.

A non-transitory computer readable storage medium, recording at least one program command, wherein the at least one program command executes an image processing method for recognizing a target object after the at least one program command is loaded into and executed by an electronic device, and the method comprising:

• obtaining an original disparity image through an image capture circuit;
• obtaining a background correlation line in a mapping disparity map according to a background region corresponding to a target object;
• and
• deleting the background region in the original disparity image based on the background correlation line to recognize the target object,
• wherein the step of obtaining the background correlation line in the mapping disparity map according to the background region corresponding to the target object further comprises:
• finding the background correlation line in the mapping disparity map,
• wherein the step of deleting the background region in the original disparity image based on the background correlation line comprises:
• obtaining an estimated background disparity map based on the background correlation line;
• and
• comparing the estimated background disparity map and the original disparity image, and deleting the background region in the original disparity image.
