立体匹配算法进展

Review of Stereo Correspondence Algorithms

立体匹配是立体视觉中的重要环节;文章首先根据匹配算法使用的约束信息的不同把匹配算法分为局域算法和全局算法,并分别进行介绍,然后,针对目前各应用领域的要求,分别从准确性和实时性方面对立体匹配算法进行分析,从软件层面和硬件层面分析准确性和实时性要求的发展过程,最后,针对立体匹配算法中兼顾准确性和实时性要求的难题,结合作者的研究,指出了可能的解决途径和进一步研究的问题。

Stereo correspondence is an important part of stereo vision. According to the difference of constraints employed by the correspondence methods, the division of local method and global method is adopted, with their introductions respectively. Then, aiming at the requirement of the application area, the stereo correspondence methods are analyzed on the aspects of accuracy and real-time, meanwhile, inuroductions of development from the aspects of software and hardware are demonstrated. Finally, aiming at the difficult problems demanded both on accuracy and real-time, according to the author＇s research, some possible approaches to solve such problems and some issues needed to be studied in a further way are given.
