摘要
为了实现对地下管线的数字化与可视化管理,结合虚拟现实技术对地下管网进行研究。系统根据分层概念和管网数据的特点,设计城市地下管网的概念模型,着重介绍栅格矢量一体化数据结构的形式,利用空间数据库将地下管网的相关信息存储在计算机上并做相应处理,最终运用GIS和LOD模型的建立实现管网系统的可视化和实时漫游功能。
In this paper, the combination of virtual reality technology and the underground pipe network has been studied. It introduces the way of how to use the spatial database to store the data about the under-ground pipe network, and how to use of GIS and LOD model of a network system to achieve the 3D visual-ization features and real-time roaming function. This paper gives the design for a general city underground pipeline information system, which is very significant in developing general underground pipeline information systems for large or medium sized cities.
