基于ArcGIS的公路全景动态仿真

Dynamic Simulation of Highway Scene Based on ArcGIS

提出了一种以ArcGIS为基础平台的公路全景动态仿真的新方法.该方法采用ArcGIS由矢量等高线地形图构建可视化数字高程模型(DEM);采用ArcObjects提供的接口编辑DEM,实现由道路设计数据生成道路主体;利用3DMax和AutoCAD对构造物、公路附属设施等三维实体进行建模;在ArcScene中完成公路场景制作,最终实现行车模拟和漫游.由此,可直观地判断公路设计的合理性与安全性,展现所设计公路的效果.该方法不仅制作周期短,而且对三维编程能力要求也不高.

A new method based on ArcGIS is introduced to realize dynamic simulation of highway scene. Firstly, visual DEM is built from vector contours in ArcGIS; and then highway model is made from design data by means of editing DEM through the interface of ArcObjects; it is finished in 3DMax and AutoCAD to model 3 dimension objects such as structures and affiliated establishments; highway scene making is completed in ArcScene; Finally, simulation of car traveling and roam is realized. Hereby, rationality and security of highway designed can be evaluated. Very strong 3D programming ability is not required for the new method, and the facture cycle is relatively short.
