摘要
采用统计试验的方法进行景象匹配算法的性能评估是当前的重要研究课题.通过统计试验建立匹配性能与图像特征指标体系之间的关系是研究的重点,因此选择一个合理的图像特征指标体系是很重要的.文中论述了评估系统中图像特征指标体系的选择问题,分析和试验指出,建立在实时图尺寸上的特征更符合理论分析结果,因而也更适于算法的性能评估和匹配区的选择.
Abstract
The Performance evaluation method of scene matching algorithm based on statistic experiment is a current important and active research field. The most important thing is to creat the relations between matching performance and image feature set. In this article, how to select the image feature set is discussed. Theory analysis and experiment show that image feature set based on real time image size accords with the result of theory analysis, and it suits for performance evaluation and matching area selection.
