基于可变窗口视差优化的并行立体匹配
Parallel stereo matching using variable window based disparity refinement
摘要
Abstract
Aiming at the trade-off between accuracy and efficiency in current local stereo matching, a real-time stereo matching method based on adaptive window is proposed. In order to compensate the precision lose on cost aggregation based on ESAW(Exponential Step Adaptive Weight), a variable window based on pixel’s color similarity and Euclidean distance is built for each unreliable point in disparity refinement stage. Then the unreliable points are further classified as“occlusion”and“mismatch”, and different refinement strategies are taken for different classifications. The proposed method is optimized with CUDA(Compute Unified Device Architecture)and evaluated on graphic processor. The experiment results show that the proposed method can produce better results than the parallel stereo matching methods listed on the Middlebury stereo benchmark.关键词
