Abstract: For the problem of textureless regions, occluded regions and depth discontinuity regions in the stereo matching, the new algorithm based on the adaptive support-weight of geobal graph segment stereo matching is proposed. On the one hand, it can reduce the matching error which happens in the depth discontinuity regions and the textureless regions by the single adaptive support-weight matching method. On the other hand, as for as the occlusion handing and smooth express in graph segment, a optimal solution is achieveding by using a certain smooth constraint and occlude constraint to build energy function. The experimental results indicate that the algorithm can guarantee the reliability of matching.
