基于景象匹配制导的飞行器飞行前需要进行航迹规划,就是在飞行区域中选择出一些匹配概率高的匹配区,作为相关匹配制导的基准,由此提出了估计匹配区匹配概率的问题.本文模拟飞行中匹配定位的过程定义了匹配概率,并提出了基准图的三个特征参数,最后通过Fisher线性分类器,实现了用特征参数估计匹配概率的目标,并进行了实验验证。
The trajectory planning needs to be done before flight for the aircraft based on scene matching guidance, which is to select some matching regions with high matching probability in the flight region as the reference of correlation matching guidance, thus the problem of matching probability of matching region is proposed. The process of matching in flight defines the matching probability and puts forward three characteristic parameters of the benchmark. Finally, by using Fisher linear classifier, the target of estimating the matching probability with the characteristic parameters is achieved and verified by experiments.
