英文摘要 | aim to the problem of initial epipolar distance transformation algorithm is sensitive to illumination and depth discontinuous, an improved stereo matching algorithm is proposed. in delta-gama log-chromaticity space, gamma correction coefficient is computed firstly according to raw disparity map which is used to modified the similarity function bandwidth. secondly, by employing image structure and color features, the segment of epipolar is obtained adaptively. at last, final disparity map is acquired by belief propagation method. experimental results demonstrate the effectiveness of the proposed transform in illumination change regions and discontinuities regions. the matching rate of proposed algorithm is improved about 60%, comparing with the initial epipolar distance transformation algorithm and state-of-art algorithm such as ancc(adaptive normalized cross correlation).
