基于MSTS与DEM数据的线路地形仿真与实现

Simulation and Implementation of Route Terrain Based on MSTS and DEMdata

三维场景仿真技术已被广泛应用于航空、城市规划、轨道交通等众多领域。该文章基于微软所开发的MSTS(Microsoft train simulation)列车运行仿真平台,以真实线路为原型,结合Google Earth地标功能,对如何快速准确复原地形进行了研究,提出利用DEM(Digital Elevation Model)数据导入,实现对仿真线路所在区域地形地貌环境的高度复原。该方法完善了仿真展示效果,提高了仿真结果的真实性与准确性。相比于传统人工修改地理参数的方式,该方法在保证一定仿真精度的前提下,通过导入DEM数据,能够大量减少复原线路地理环境的工作量。

3D simulation technology has been widely applied to many fields such as aviation,urban planning,rail transportation etc. Howto recover the terrain of the simulation zone quickly and accurately based on MSTS（ train simulation Microsoft） platform by taking the real route as prototype and combining with landmark of Google Earth was studied. By importing DEM（ Digital Elevation Model）data to realize the terrain recovering of the simulation zone which contains the route has improved the authenticity and accuracy of simulation result. Under the premise of ensuring the accuracy,compared with traditional method that modifying geographical parameters manually,importing DEMdata could reduce the workload of the recovering of geographical environment greatly.
