摘　　要：This paper develops a method which can be used to assist aerial navigation by determining the spatial position and posture of the aerial photographic plane. After the method, aerial images match known DEM to capture the spatial position and posture. Some aerial images and terrain data are used to testify our method. Compared with those of analytic and stereo mappers, the results by our method are correspondent to real measurements well.This paper develops a method which can be used to assist aerial navigation bydetermining the spatial position and posture of the aerial photographic plane.
