Visible Simulation Research on Terrain Scene Matching Aided Navigation and Software Realization

In order to validate the terrain scene-matching algorithm and demonstrate the process of the terrain-aided 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 system 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.
