景像匹配中重复模式的分析

景像匹配参考图中存在的重复模式重重影响匹配概率及匹配可信度，景像匹配要求精度与匹配概率同时满足一定的要求，若参考图中存在重复模式，对匹配的精度和概率必定产生一定程度的影响。

ANALYSIS OF SIMILARITY-PATTERN IN SCENE-MATCHING

The similarity-pattern in reference map has great effect on the perfor-mance of scene-matching ' s probability of fix and match confidence. Accuracy and confi-dence must be satisfied to the requirement, if reference map consists of similarity-pat-tern, the accuracy and confidence must be influenced, so the measureinent of similarity-pattern in reference map is the key step in scene-matching. The amount of similarity-pattern is an important index of reference map's matching performance, and directly af-fect the probability of fix. In this paper, We studied the measurement of similarity-pat-tern based on Fourier spectrum and the method of calculating the ratio of similarity-pat-tern, and analyzed the gray level image, edge enhanced image, and binary edge imageof reference map, and offered a rule of measurement of reference map's matching per-formance.
