使用视差一致性约束的立体匹配与遮掩检测

在视差空间内分析了立体视觉中的遮掩与匹配问题后，针对已有的双目立体匹配约束规则的缺陷，提出了基于视差空间左右视线冲突检测的视差一致性约束的概念。这种约束的优点在于其正确性与完整性，能适应更多的复杂场景而不至于失效。同时提出了一个利用一致性约束的匹配与遮掩检测算法。实验的结果表明，由于使用快速相关匹配值计算，其运算速度有了极大提高，更重要的是由于视差一致性约束的使用，使得即使出现复杂场景也能得到很好的结果。

Stereo Matching and Occlusion Detection Using Disparity Consistency

Stereo matching and occlusion detection is analyzed in disparity space explicitly, and the concept of disparity consistency is introduced after the analysis of some commonly used constraints and some cases of occluding. The advantage of disparity consistency over those existed constraints is the correctness and robustness (more accurate and will not fail in most cases). An algorithm using disparity consistency is provided. With this consistency constraint, the occluding problem in the complex scene can be solve better than with the existed constraints and other methods. The experiment result on synthesis image and real world images are presented.
