摘　　要：为提高景象匹配算法的匹配性能,分析匹配算法设计的基本思路及常见两类匹配算法的优缺点,提出采用一定的控制策略以加快匹配速度,进而提高匹配效率的思想,给出几种匹配控制策略的设计思路。以归一化积相关景象匹配算法为例,采用先粗后精的分层匹配策略,实现了算法的加速,通过大量的匹配仿真实验,验证了该匹配控制策略的可行性、有效性。To improve the performance of scene matching algorithm, the basic ideas of matching algorithm design and the merits and demerits of two common types of scene matching algorithm are firstly analyzed in this paper. Then, approaches to speed up the algorithm matching and improve the matching efficiency by adopting certain control strategy are proposed. And several matching control strategy design principles are given in the following part. Finally, taken normalized product correlation algorithm as an example, the matching is accelerated by using a coarse-to-precise hierarchical matching control strategy. The simulation matching experimental results demonstrate the feasibility and efficiency of the control strategy.
