A study on the correlation coefficient matching algorithm of general digital stereo under the approximate epipolar line constraints

By analyzing the features of general digital image and calculating the deviation of epipolar line, a correlation coefficient matching algorithm is proposed. In this paper, we make a summery of the particularity of general digital stereo, analysis the deviation of the corresponding epipolar line, and provide a matching method under the epipolar line constraint. It is proved by experiments that this algorithm can conquer image deformation well and has a higher matching accuracy and speed.
