摘　　要：针对相关匹配法计算量大的缺点提出了一种快速匹配算法。该算法采用由粗到精的匹配策略,对匹配区域先用环形模板进行粗匹配以确定待匹配窗口,再用全模板进行精匹配以确定正确匹配窗口。将该算法用于遥感图像匹配,仿真结果表明,该算法不仅能够实现正确匹配,而且计算量只有相关匹配法的10%。A fast matching algorithm is proposed aiming at the fault of large calculation quantity in the correlation matching algorithm. A coarse-to-fine strategy is adopted in the new algorithm, i.e., a circular template is used in matching area to complete the coarse matching such that the matching windows can be determined firstly, and then the whole template is used to decide the final correct window. This algorithm is applied to remote sensing image matching. The simulation results show that the algorithm can carry out correct matching and its calculation quantity is only 10% of that of the correlation matching algorithm.
