| 摘 要： | 通过综合分析将DTM(Digital Terrain Mode)应用于道路工程的相关研究,提出一种改进的“方向搜索”三角网简化算法;并根据道路的带状特征,建立了边——三角形的拓扑关系;基于Windows平台,利用分治算法和逐点插入算法,采用VC++的MFC和OPENGL语言编程,实现基于DTM计算并生成道路和地形整体三维模型。经测试,证明本文提出的计算理论合理、简单、且执行效率高。

| Abstract: | By synthetically analyzing the interrelated research on using DTM(Digital Terrain Mode) for a road project,a compact way of the improved "direction search" triangle net is put forward,then according to the sheet character of a road,the topology relation of edge-triangle is built.Based on Windows flat,using the method of polarization and the method of point-by-point insert,and adopting MFC of VC and OPENGL language programming,the integral three-dimensional model are calculated and built based on DTM.By testing,it is proved that the calculation theory put forward in this article is reasonable,simple,and high efficient. |
