通过试验研究了景象匹配概率与实时图的独立像元数、方差、纹理能量比和互相关峰等图像特征的关系,并以此提出了基于这些图像特征的景象匹配区选择方法.图像测试结果表明,该方法可以成功地规划出满足要求的景象匹配区.

A new method to select the reference map for mission planning of unmanned aircraft navigated by scene matching is presented. The method depends on the matching probability and the feature of the reference map, such as independent pixel numbers, variance, pattern energy ratio and cross-correlation peak. Finally an example of reference map is programmed, the experimental result is almost the same as the test result which is based on satellite images sensed in different time.
