| 摘 要： | 建立行星地形激光测高的可视化仿真系统对于卫星探测中行星地形信息的处理具有重要的意义。采用分形技术仿真了行星数字地形,计算了卫星轨道数据和测量点信息。对测量的高程信息通过插值算法得到了规则的DEM,动态地三维展示了整个探测过程的卫星轨道和测量点分布情况,并通过基于LOD的地形生成算法显示了原始的行星地形和测得的地形对比。

| Abstract: | The development of a visual simulation system for planet terrain laser ranging is very important to the processing of planet terrain information. The digital planet terrain is simulated by using a fractal method and the satellite orbit data and the survey point distribution are calculated. The regular DEM is obtained for the surveyed terrain information and the 3D scene of satellite orbit and survey point distribution in the survey are demonstrated dynamically. The difference between the original terrain and the surveyed terrain is displayed through a terrain render algorithm based on LOD. |
