摘 要: 针对现有适配指标存在的问题,提出一种基于CR-DSmT多指标融合的景象匹配辅助导航适配性分析方法。首先提出多个改进适配性评价指标,然后将基准图的适配性分析看作多个适配指标融合的推理过程,在同时包含冲突和不确定的DSmT框架下加以分析。实验分析结果证明了所提算法的有效性。
关 键 词: 导航制导与控制;CR-DSmT;相位相关长度;有效轮廓密度;多尺度边缘密度;适配性分析

Abstract: To deal with existing problems of matching suitability, this paper presents a scene matching suitability analysis method based on CR-DSmT, which fuses multiple metrics to provide the robust selection of suitable matching areas. Firstly, this paper analyzes and presents some improved suitability evaluation metrics, and then poses the suitability analysis on the reference image as a reasoning process with these multiple metrics, which puts the conflict and uncertainty into the DSmT framework. The experimental analysis results indicate the validity of this proposed method.
Key words: guidance, navigcation and control; CR-DSmT; phase correlation length; effective contour density; multi-scale edge density; suitability analysis
