Disparity estimation depth generation method

Abstract

A disparity estimation depth generation method, wherein after inputting an original left map and an original right map in a stereo color image, compute depth of said original left and right maps, comprising following steps: perform filtering of said original left and right maps, to generate a left map and a right map; perform edge detection of an object in said left and right maps, to determine size of at least a matching block in said left and said right maps, based on information of two edges detected in an edge-adaptive approach; perform computation of matching cost, to generate respectively a preliminary depth map, and perform cross-check to find out at least an unreliable depth region from said preliminary depth map to perform refinement; and refine errors in said unreliable depth region, to obtain correct depth of said left and said right maps.
