摘　　要：在立体匹配技术中,宽基线匹配技术具有更广泛的应用领域。在宽基线条件下,由于摄像机视点范围的变大,使得同一空间目标在两视图上的方向和尺度都发生变化。同时,透视变形使得目标的形状也发生变化,所以需要选择具有仿射不变特性的局部特征实现立体匹配。文中对近年来的基于特征的宽基线立体匹配技术进行了归类总结,包括特征提取算法及算法分析、相似性度量方法以及误匹配的剔除算法等。最后指出了宽基线立体匹配算法迫切需要解决的问题。In stereo matching technology, wide baseline stereo matching technology has more wide application than small baseline. In the wide baseline, due to the change of camera view range, make the same space target in two views on the direction and scale are changed. At the same time, perspective deformation causes the change of target shape, so need to choose the local characteristics with affine invari- ant properties to realize stereo matching. In this paper, wide baseline stereo matching technology based on features was summarized and classified, including the features extraction algorithm and analysis, similarity measures method and error matching elimination method etc. Finally, point out the problems need to solve urgently in wide baseline stereo matching algorithm.
