一种快速区域立体匹配算法设计及实现
Realization of Two-way Stereo Matching Algorithm
摘要
Abstract
In order to set up the corresponding relationship between pixels of two homologous images accurately and overcome the shortcomings of large amount computation in method, an improved stereo matching algorithm is proposed. The improved area-based stereo matching algorithm adoptes the two-way stereo matching strategy to improve the accuracy of matching between pixels of two homologous images. The dense parallax error of image is obtained in combination with the mean-shift image segmentation technology under the assumptions of the same area with the same parallax. Meanwhile, in order to conquer the disadvantage of large amount computation of the area-based stereo matching algorithm, the pseudo-epipolar constraint is introduced by this algorithm to limit the location of the true matching point in a very small area. Therefore, the search range of matching point is reduced significantly, and the computation amount of matching algorithm is decreased efficiently. The experiments results show that the improved algorithm can effectively reduce the matching range and achieve the exact dense matching between images.关键词
