摘要
以目前城市规划管理部门所探测的二维地下管线数据为基础,依据现有的管线二维数据库,利用C#编程语言,实现管点、管段及管段连接部件自动套合的自动建模方法,完成由管线空间库到管线模型库的自动建模,形成一个成熟的、单体化的地下三维管线的Collada模型库。该模型库具有依赖小、算法快应用范围广,可动态更新等优点。使模型库、空间库、属性库相互关联、实现相互调用,并将此成果应用到了现有的地下管线二三维一体化应用系统中。通过自动创建城市地下三维管线模型库,极大地提高了生产的效率,节约了人工手动建模的成本。为智慧地下空间、实景三维、数字孪生等项目建设以及WebGL三维视角下的地下管线分析、规划、设计以及施工运维管理提供了关键的技术。
Based on the two-dimensional underground pipeline data detected by the current urban planning and management department,the automatic modeling method of automatic fitting of pipe point,pipe section and pipe connection part is realized by C # programming language according to the existing pipeline two-dimensional database From the pipeline space library to the pipeline model library of automatic modeling,the formation of a mature,single underground three-dimensional pipeline Collada model library,with a small dependence on the algorithm,a wide range of applications,dynamic updates and so on.So that the model library,spatial library,attribute library are interrelated to achieve mutual call,and this results applied to the existing underground pipeline two three-dimensional integrated application system.Through the automatic creation of urban underground three-dimensional pipeline model library,greatly improve the efficiency of production,saving the cost of manual manual modeling.It provides key technologies for the construction of smart underground space,real 3D,digital twin and other projects,as well as the analysis,planning,design and construction operation and maintenance management of underground pipelines from the perspective of WebGL 3D.
