| 摘 要： | 针对景象匹配辅助导航中,由于噪声、云层、摄像机抖动等原因导致的景象匹配可能输出错误匹配结果情况,提出一种基于证据推理的景象匹配末端置信度评估方法.首先建立序列帧时空约束关系,对匹配相关阵中峰值构建辨识框架,计算序列帧对各峰值的置信指派并利用适配因子进行折扣运算,然后采用证据推理组合规则进行融合,最后给出判决准则输出匹配...

| Abstract: | A novel scene matching terminal evaluation method based on evidence theory is put forward for scene matching aided navigation system,to deal with potential fault output because of noise,cloud,camera jittering and so on.The spatial-temporal correlation of sequence frames is founded firstly,and the identification framework is constructed with the maximal peaks of the matching correlation matrix.Then the basic belief assignment of the peaks is calculated,and the discounting operation is processed using suitabl... |
