实景三维铁路构建方法研究

Construction method of real scene 3D railway

为提高铁路工程实景三维技术应用系统化、标准化和多专业、多场景综合应用水平,结合实景三维中国建设整体框架及数字铁路建设需要,对实景三维铁路构建技术进行研究;提出了实景三维铁路构成及地理场景、地理实体、铁路实体等基础数据制作方法;阐述了实景三维铁路的数据库设计、数据库管理及应用服务平台搭建方法,实现多源海量空间数据的统一组织管理、三维场景构建、空间分析应用及在线数据服务。该研究为铁路工程管理提供一体化的三维数字场景,可满足勘察设计、施工建设及运营维护阶段应用需要,提升铁路工程建设管理数字化、智能化水平。

In order to improve the systematic,standardized,multi-disciplinary,and multi scenario comprehensive application level of real scene 3D technology in railway engineering,this paper combined the overall framework of real scene 3D construction in China and the needs of digital railway construction to study the construction technology of real scene 3D railway.It proposed the composition of real scene 3D railway and the production methods of basic data such as geographic scenes,geographic entities,and railway entities,and elaborated on the database design,database management,and application service platform construction methods of real scene 3D railway,implemented unified organization and management of massive spatial data sources,3D scene construction,spatial analysis applications,and online data services.This study provides an integrated 3D digital scene for railway engineering management,which can meet the application needs of survey and design,construction and operation maintenance stages,and enhance the digitalization and intelligence level of railway engineering construction management.
