地形匹配制导技术研究

Study on the Technology of Terrain Contour Matching Guidance

指出了匹配系统的性能与地形的选择有很大的关系 ,给出了地形高程数据的标准差、粗糙度和相关特性等概念 ,反映了特定区域内地形的总体起伏、局部变化及领域相关性的强弱 ,对地形匹配区的选择具有重要意义。同时 ,利用Hausdorff距离作为地形匹配算法的相似性度量 ,对应最小的Hausdorff距离是最佳匹配。实验结果表明该方法的有效性。

This paper points out that the performance of matching system has a close connection with terrain choice.And concepts of standard deviation, roughness and correlation character are given, which reflects respectively terrain global wave, local variety and correlation character of adjacent areas in a specific field and of great importance for the selection of the terrain matching field. At the same time, The algorithm to match terrain using Hausdorff distance as the measure of the difference between two image is presented and the minimal Hausdorff distance means the best matching result. The experimental result shows the method is effective for matching terrain.
