| Abstract: | 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. |
