摘要
针对多源遥感影像的像点匹配问题,提出了一种结合相关系数法和最小二乘法的多影像自动匹配算法。该算法采取由粗到细的匹配策略,首先通过影像上像点间的坐标差值估算出基准影像上的待匹配像点在各影像上的大致位置,然后运用相关系数法进一步精匹配,最后采用基于最小二乘法的多影像匹配算法确定最佳匹配点位。实验结果表明,该算法匹配成功率高、运行速度快。
For matching multi-source images,a matching algorithm which combined correlation coefficient and multi-image least squares match method and used coarse-to-fine matching strategy is proposed in this paper.The algorithm calculated approximate offsets between each image and the reference image to determine the approximate location of points to be matched on the reference image.Then using correlation coefficient method further provides an initial position for multi-image least squares matching.Finally,determine the best match points by multi-image least square match.
