中文摘要：

遮挡会引起不同视角图像中特征间“一配多”和“多配多”的复杂对应关系，是特征立体匹配面临的主要难题之一。本文提出一个遮挡存在条件下直线特征间对应关系的求解模型，在此基础王实现了一种能够完整建立各种对应关系的直线立体匹配算法。

英文摘要：

Occlusion is one of the difficulties involved in stereo matching, which can result in various complex correspondences such as ＂one-to-many＂ and ＂many-to-many＂ ones among the features extracted from different images. The paper proposed a mathematic model for establishing the correspondences between line features from different images under occlusion, based on which an algorithm for stereo line matching was put forward.
