Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] refer to figure 1 -2. Image matching method for occluded areas based on pixel blocks, based on the reference image f B ( i , j ) as the benchmark, in the reference image f C ( i , j ) to find matching points to form a disparity map d ( i , j ), where the pixels that cannot be successfully matched are listed as occluded pixels O( k , j ), where 0≤ i j k < M, the coefficient M is the pixel width of the image, and the coefficient N is the pixel height of the image.
[0017] The image matching method of the occluded area comprises the following steps:
[0018] (1) The reference image in the f B ( i , j ), select the occluded pixel O( k , j ) as the points to be matched, and construct a rectangular occluded pixel block {O( k +1, j +1),O( k -1, j -1), O(k +1, j -1), O( k -1, j +1), O( k +1, j ), O( k -1, j ), O( k , j -1),O( k , j +...
