基于二维地下管线数据快速建立地下管网三维场景

Building Underground Pipe Network of 3D Scene Quickly Based on 2D Underground Pipeline Data

随着地下空间应用的不断深入,二维信息不能准确表达管线之间的空间关系,三维空间信息系统更加适合地下空间数据的表达。本文主要论述了二维地下管线数据向地下管网三维场景的快速建立,以及在建立过程中出现的各种问题,经反复实验解决问题,最终实现了地下管网三维场景的快速构建、三维管线浏览、信息查询等功能。

With the dee： ing of the application of underground space, the 2D information can＇t accurately express the spa tial relationship betweel e line, the 3D space information system is more suitable for underground space data expres- sion. This paper mainly usses the 2D underground pipeline data to the underground pipe network of 3D scene quickly built, and a variety of prob ms in the process of building, solves the problem after repeated experiments, finally achieves the un- derground pipeline network of 3D scene to quickly build, 3D pipeline browsing, information query, and other functions.
