【摘要】 景像匹配参考图中存在的重复模式严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。因此，度量参考图中的重复模式是景像匹配的重要步骤之一。重复模式的多少是衡量参考图可匹配度的重要指标，直接影响匹配概率。文中研究了频域内重复模式的度量以及统计重复模式占参考图百分比的方法，并分别对参考图的灰度图、边缘增强图及二值化边缘图进行了分析，提供了参考图可匹配度定量分析的依据。更多还原

【Abstract】 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.更多还原
