摘要
采用遗传算法研究了图像相关匹配问题，提出了快速图像相关匹配算法在最优匹配的前提下，其计算量较ＳＳＤＡ算法降低了一个数量级以上；可以采用ＮＰＲＯＤ匹配准则，改善在低图像对比度条件下的匹配精度；该算法每帧图像匹配计算时间基本恒定。
The problem of image correlative matching was studied by means of genetic algorithm and a fast image correlative matching algorithm was presented. With the condition of optimum matching, the computation amount of the algorithm was reduced more than 10 times compared with SSDA algorithm. The NPROD matching criterion can be employed in this algorithm to improve the matching precision for the case of low image contrast. The computation time is nearly constant for matching each frame of images in the presented algorithm, which brings convenience to the practical application.
