摘要
利用Google Earth卫星影像和地理测量数据,借助ArcGIS和CityEngine软件平台构建三维数字校园,对陕西理工大学南校区构筑物矢量化和三维模型构建,实现数字校园的三维场景设计与可视化。在CityEngine三维建模过程中,使用ArcScene和3D Max纹理贴图,能有效地进行地物三维模型表达,并实现具有界面浏览、位置导航、信息查询、量算统计等功能的数字校园可视化系统。
In order to evaluate the possibility of acquisition of geographic information and engineering measurement based on high-resolution image,the ArcGIS and CityEngine software are employed for constructing the three-dimensional virtual campus of Shaanxi Sci-Tech University.The 3D virtual digital campus visualization is developed by CityEngine platform,when the object vector dataset is finished with the support of ArcMap.Before the 3D modeling in the CityEngine software,the surface features of 3D model expression was carried out in ArcScene and 3D Max.The interface of the three-dimensional virtual digital campus system is of browsing,position navigation,information query as well as the calculation module and the statistics function.
