摘　　要：本文将近年来兴起的小波理论应用于双目立体视觉技术,提出了一种新的立体匹配算法。该算法以二进小波变换的多分辨率零交叉为匹配基元,综合利用了小波变换零交叉的特征属性和强有力的匹配约束,从零交叉局部属性相似和全局匹配相容两个方面解决模糊匹配问题。整个系统采用一种新的由粗到细引导的多分辨率匹配结构。实验结果表明,该算法结构简单,稳定可靠,具有较好的自适应性和处理复杂景物的能力。This paper proposes a new algorithm for stereo matching which utilizes the wavelet transform theory developed recently. The multiresolution zero-crossings of dyadic wavelet transform are used as matching primitives. The matching approach utilizes the characteric of wavelet transform zero-crossings and the power matching constraint to resolve the ambiguity of matching in local feature similar and global matching consistency, and the system uses a new coarse-to-fine multiresolution matching stragy. Experimental results show that the algorithm is simple, reliable and capable of adaptable coping with complicated real scenes.
