摘要
运用虚拟现实技术以及GIS将传统地图与虚拟三维场景结合起来,实现校园信息的查询浏览和动态交互管理。使对数字校园的漫游、查询等各项功能更加完善。给用户创建了一个更好的了解校园的平台,构建虚拟三维校园的基础是三维模型的构建,本文把桂林理工大学雁山校区作为研究对象,利用无人机拍摄的高分辨率影像作为数据源,通过结合MAPGIS进行影像配准、矢量化。最后采用SketchUp作为三维建模工具,实现了虚拟三维校园模型的构建。
By using virtual reality technology and GIS,traditional maps and virtual three-dimensional scene can be combined to achieve query browser and dynamic interaction management of campus informat ion,and thus makethe various functions of the digital campus such as roaming and inquiry more perfect.This platform to better understand the campus enables users to more directly know the school environment in all aspects.The fundament of building a virtual three-dimensiona campus is to build the three-dimensional model.This paper,taking the Yanshan campus of Guilin Technology University as the object and the high-resolution images taken by drones as a data source,achieves registration and vector quantization for images by combining MAPGIS.Finally,this paper adopts SketchUp as a three-dimensional modeling tool and achieves the building of a virtual three-dimensional campus model.
