摘要
针对管线工程应用中存在的三维图形自动化建模效率低、多源数据整合难等问题,本研究以Cesium开源引擎为基础,研究BIM+GIS多源数据创建、融合与应用的关键方法,包括基于现状管线和地质勘察数据自动建模、无人机倾斜摄影和实景模型创建,以及多源数据预处理及轻量化方案等,并进一步开发BIM+GIS数字化平台,结合项目信息查看和交互需求定制开发功能模块。本研究提出的解决方案已在长沙市雷锋水厂原水管线等项目中得到应用和验证。
There are some problems in the application of pipeline engineering,such as low efficiency of automatic modeling of three-dimensional graphics and difficult integration of multi-source data.Based on Cesium open source engine,this paper studies the key methods of BIM+GIS multi-source data creation,fusion and application.The automatic modeling based on the current pipeline and geological survey data,UAV oblique photography and real scene model creation,as well as multi-source data preprocessing and lightweight scheme are formed.The BIM+GIS digital platform is further developed by combining the project information viewing and interactive requirements to customize the development function module.The solution proposed in this study has been applied and verified in the raw water pipeline project of Changsha Leifeng water plant.
