| 摘 要： | 图像匹配是立体视觉中的关键问题。本文针对在图像匹配中被广泛采用的最小二乘算法存在速度慢、易受初值影响的问题,提出了一种基于小波金字塔分层的快速立体匹配算法。形成由粗到精的匹配策略,以低分辨率下匹配点,作为高分辨率图像对匹配的约束。实验结果表明此算法可以减少误匹配,提高匹配速度。

| Abstract: | Image matching is the key of stereo vision.Least square matching (LSM) is widely used in Stereo matching owing to its high precision,but traditional LSM has its drawbacks about low speed and easily effected by the first value.Point to the problems,this paper proposes a multi-resolution stereo matching method based on wavelet pyramid.Form the strategy that is form rough to accuracy,let the matching point in low resolution be the restrict of matching in high resolution.The results confirm the proposed algorit... |
