将数字高程图的应用扩展到计算机视觉领域。提出了一种地形匹配算法，使无源飞行器导航系统成为可能。将一系列航拍图像与3D地形的数字地图的参考进行匹配。连续图像的立体分析导致恢复的高程图。悬崖地图，然后作为一种新颖的，紧凑的表示的3-D表面。经由在参考悬崖地图内定位未知悬崖地图的地形匹配算法来确定飞行器的位置和航向。利用真实的地形数据进行的实验结果证明了该匹配算法的鲁棒性。<<ETX>>
The application of digital elevation maps is extended to the field of computer vision. A terrain matching algorithm that makes possible a passive aircraft navigation system is presented. A sequence of aerial images is matched to a reference to a digital map of the 3-D terrain. Stereo analysis of successive images results in a recovered elevation map. A cliff map is then used as a novel, compact representation of the 3-D surfaces. The position and heading of the aircraft are determined via a terrain matching algorithm that locates the unknown cliff map within the reference cliff map. The robustness of the matching algorithm is demonstrated by experimental results using real terrain data.<<ETX>>
