In order to solve the problem that dynamic programming (DP) stereo algorithm is slow, a local-global stereo matching algorithm is presented. In this method, local and global stereo algorithms are united to apply to the stereo vision field.

    Design/methodology/approach

    Local and DP stereo algorithms are used. Multi-resolution images are obtained by pyramid algorithm and matching costs are gained by using eight-stripe correlation window.

    Findings

    The time of disparity space image creation is greatly reduced because matching costs are computed by eight-stripe window. Candidate ground control points (GCPs) are gained in the low-resolution image. The total time of gaining GCPs is decreased in the extreme. Whole algorithm has a high matching-rate and a fast speed.

    Research limitations/implications

    The time of the whole algorithm is still a little bigger than local algorithm.

    Practical implications

    The findings can be used in the stereo vision system equipped with planet vehicle.

    Originality/value

    Local and global stereo algorithms are united to apply to the stereo vision field. Matching costs are gained by using eight-stripe correlation window.
