摘要:

立体匹配算法中的SAD算法与Census算法较为常用,本文分析了两种算法的特点,在改进SAD算法后,将其与Census算法融合,提出了自适应权重的SAD-Census算法。试验表明,与SAD算法和Census算法相比,该算法匹配效果更好,对实际场景拍摄图像的匹配也有较好的稳健性。

关键词: 立体匹配, Census变换, 自适应权重SAD, 融合算法

Abstract:

The SAD algorithm and Census algorithm are commonly used in stereo matching. In this paper, the characteristics of the two methods are analysed. After the SAD algorithm is improved, and it is fused with Census to propose SAD-Census algorithm with adaptive weights. The experiments show that, compared with traditional SAD algorithm and Census algorithm, the proposed algorithm is more efficient and robust to the matching of actual scene images.

Key words: stereo matching, Census transform, adaptive weight SAD, fusion algorithm
