Method, image processing device, and system for generating depth map

A system for generating a depth map, comprising:

• a first image sensor and a second image sensor, configured to capture images so as to respectively generate a first original image and a second original image;
• a memory, configured to store data;
• a processor, connected to the first image sensor, the second image sensor, and the memory, and configured to:
• obtain the first original image and the second original image, and obtain a plurality of first edge blocks corresponding to the first original image and a plurality of second edge blocks corresponding to the second original image;
• generate depth information of a plurality of matched edge blocks according to the first edge blocks and the second edge blocks;
• set depth information of a plurality of non-edge blocks according to the depth information of the matched edge blocks and depth-filling directions of the matched edge blocks, wherein the depth information of each of the non-edge blocks is associated with the depth-filling directions of the matched edge blocks neighboring to the non-edge blocks, and the depth-filling direction of each of the matched edge blocks is associated with a similarity between the matched edge block and a neighboring non-edge block of the matched edge block;
• and
• generate the depth map by using the depth information of the matched edge blocks and the depth information of the non-edge blocks.
