摘要
分析了现有铁路3维设计曲面与地形DEM融合中存在的问题,提出了一种新的适用于铁路仿真的DEM数据融合方案,给出了其基本思想和实现步骤,并通过试验证明了该方案的可行性及有效性。
On the basis of analyzing data fuse problems on 3d railway design data and topographic DEM data,the paper presents a new DEM data fuse solution which can be employed in railway simulation, gives its basic arithmetic and flow to make it reality. At last a test is employedto prove the solution's feasibility and its validity.
