摘要
为了直观有效验证地形景象匹配算法和演示地形辅助导航的过程,设计了地形景象辅助导航可视化仿真软件系统。利用V isual C++和OpenGL的功能实现了对导航数据和飞行过程的动态二维可视化曲线显示,对匹配区域中的实测图和参考图进行动态显示,能够直观地分析匹配结果的正确性;并在此基础上着重对地形景象匹配辅助导航过程实现了可视化仿真显示,能形象直观地演示地形景象辅助导航的过程及其性能。通过多次试验表明,该软件能很好地演示地形景象辅助导航系统的全过程及其性能,具有很好的实际应用价值。
In order to validate the terrain scene - matching algorithm and demonstrate the process of the terrain - ai- ded navigation effectively, this paper designs a visible simulation software system for the terrain scene matching aided navigation. Using Visual C＋＋and OpenGL, the system realizes the demonstration of the navigation data and the flight process with two-dimensional dynamic and visible curves. Within the matching regions, the survey maps and the reference maps could be displayed dynamically. And the paper analyzes the accuracy of the matching results. Also this sys- tem emphatically realizes the visible simulation display of the process of the terrain scene matching aided navigation and could demonstrate the process and the performance of the terrain scene matching aided navigation visually. The experiments suggest that this software could demonstrate the entire process of the terrain scene matching aided navigation system and its performance perfectly. And this software proved that it has the very good practical application values.
