(一)引言从高空、低空飞机机载传感器得到的图像有许多用途,包括导航标志,自然资源分析和天气予报。当希望用不同观测位置上的不同传感器取得的同一景物的两个图像对同一个目标进行定位的话,就出现了这些图像分析当中的基本问题。例如,为了证明雷达传感器的精度,而对景物的两个光雷达图像的特征进行定位或者为了研究其变化而对在不同天气条件下取得的两个光图像的特征进
(A) Introduction Images from aerial and low-altitude aircraft airborne sensors have many uses, including navigation signs, analysis of natural resources and weather reports. The basic problem with these image analysis arises when two images of the same scene taken from different sensors at different observation positions are to be located on the same object. For example, in order to prove the accuracy of a radar sensor, the features of two light radar images of a scene are located or the characteristics of two light images taken under different weather conditions are studied in order to study the changes
