| 摘 要： | 提出了由粗到细的层次景象匹配区选取准则,定义了稳定强度和广义最高峰尖锐度,从匹配区选取的策略上分析了匹配区的选取问题.首先选出信息量足够多的匹配区,再从中筛选出信息量足够强的匹配区,最后利用唯一性的判断,排除匹配区相关面多峰值的情况,选出最佳匹配区.通过这样的逐层筛选,实现了匹配区选取的逻辑性和合理性,可以满足景象匹配的要求.

| Abstract: | This paper provides a hierarchical way of selecting optimal scene matching area and defines the measurement of the stable intensity and generalized peak acutance. The new method analyzes strategically the way of selecting the matching area. Firstly the matching region with enough information is selected. Secondly the region with prominent information is screened out from the region acquired by the first step screening Lastly the optimal matching area is screeneed out according to the unique characteristic from the region acquired by the second step screening. The method, which is logical and reasonable, can meet the matching requirements. |
