摘要
Abstract
3D pipeline model is one of the important basic data for building digital twin cities.Manual modeling based on pipeline CAD drawings and pipe point elevation is time-consuming and labor-consuming,which is difficult to meet the actual engineering needs.A method of automatic generation of 3D pipeline model based on hypergraph GIS platform is presented in this paper,which can quickly build massive 3D pipeline models.First,the tabular data of pipeline results are converted into pipe points and pipeline layers in hypergraph GIS format.And then,the 3D network data set of pipeline is constructed based on the pipe points and pipeline layer.Finally,the data set is symbolized to generate a 3D pipeline scene.The 3D pipeline model format constructed based on this method has strong universality.It can be seamlessly integrated with 3D real data and other GIS data to realize the three-dimensional integration of above ground and underground.It can intuitively display the relationship between pipelines and the surrounding environment,and can conduct pipeline collision detection,pipeline demolition statistics and other analysis.关键词
