摘　　要：建设虚拟现实的关键技术是构建虚拟场景,然而虚拟场景的构成存在复杂性和管理编辑困难等缺点。将地理信息系统和虚拟现实结合在一起是探索计算机仿真的重要应用。结合3DGIS,Arc GIS,Google Earth,osg Earth等地理信息系统实现虚拟校园的建设是一个新的方向。以大连海事大学为例,选择对建模要求较高的Multi Gen Creator进行建模,利用osg Earth的分析功能优势和对OSG语言进行特定功能的二次开发。建立数字地球图,使用Google Map数据和三维模型实现了大连海事大学虚拟场景的功能建设。The key technology of constructing virtual reality is to build a virtual scene.However,the structure of the virtualscene is complicated and difficult to edit and manage.Combining the geographic information system(GIS)with the virtual reali?ty technology is an important application of computer simulation research.Adopting geographic information systems such as3DGIS,ArcGIS,Google Earth and osgEarth to realize virtual campus construction is a new innovation.In this paper,DalianMaritime University is taken as an example and MultiGen Creator with high demand for modeling is chosen.The superiority ofanalysis function of osgEarth is utilized for the secondary development of the specific function of the OSG language.The digitalearth map was created.Google Map data and3D models are used to realize the virtual scene functional construction of DalianMaritime University.
