| 摘 要： | 匹配区的适配性分析在景象匹配视觉导航中至关重要。目前已有很多匹配区适配性分析特征指标，但都只能片面说明匹配区的适配性。试图将多种特征指标进行综合，解决不同特征指标对适配性分析的冲突性，提出一种特征指标适配置信度和不确定置信度的度量方法，利用Dempster-Shafer (D-S)证据理论对置信度进行融合，得出匹配区适配综合置信度，实验验证了该算法的有效性。

| Abstract: | The suitability analysis of matching area plays a significant role in the field of vision-based navigation. There are many feature indexes that can only unilaterally describe the suitability of matching area. An algorithm was proposed to integrate several feature indexes to solve conflicts among different feature indexes and provide a kind of method that can measure the suitable confidence and unsuitable confidence of a feature.And then the confidences were fused by using the Dempster-Shafer (DS) rules. At last the algorithm was verified by simulation experiment. |
