Abstract: In the process of urban terrain building,the density of elevation points is often too thin to meet the requirements of building terrain,so must be interpolated.This paper puts forward the method of Frame Terrain Modeling which constructs the high precision terrain modeling without densification of elevation points.It also takes 3D virtual campus simulation of Shandong Normal University based on Multigen Creator/Vega as an example.The result proves the technical route reasonable and feasible.

摘要: 在城市地形建模过程中,由于目前所采用的数据源的高程点密度不能达到高精度地形建模的要求,往往需要内插高程点。提出了基于GIS的“框架式地形建模”方法,在一定条件下不用加密高程点,就可以构建高精度的地形模型。以山东师范大学校本部的地形建模为例,采用基于Multigen Creator/Vega虚拟现实软件平台进行了实证研究,实验结果表明利用该方法可以满足高精度仿真对于地形建模的要求。
