基于BIM+Cesium三维可视化校园系统的设计与实现

构建具备“三维可视化”、“信息化”、“数字化”特征的校园平台是智慧校园建设的基础点,现有校园平台大多使用传统建模工具融合C/S架构的GIS平台搭建,缺乏模型信息统一整合、趋于平面化且可视化水平较低、不具备跨平台等问题;BIM技术因其数据整合模式有效提高了建筑业信息化水平,文章结合BIM技术二三维信息整合及WebGIS-Cesium框架免插件、可跨平台的优点,以本校作为建模原型借助Revit软件建模及二次开发、文件流等技术,基于B/S架构开发兼备可视化、信息化及跨平台能力的校园平台,实现了地图显示模块、建筑物信息查询模块、空间GIS模块、地物对应查询模块及其子功能;通过测试,设计的系统工作可靠可行,满足校园平台需求。

Design and realization of BIM+WebGIS 3d campus visualization system

Building a campus platform with the characteristics of "3D visualization", "informatization", and "digitalization" is the foundation of smart campus construction. Most existing campus platforms used traditional modeling tools and GIS platforms built with C / S architecture. There are problems such as lack of unified integration of model information, tending to be flat, low level of visualization, and lack of cross-platform. BIM technology has effectively improved the level of construction industry informatization because of its data integration model,This paper combines the advantages of BIM technology two- and three-dimensional information integration and WebGIS-Cesium framework plug-in-free, cross-platform advantages, using our school as a prototype for modeling and Revit Secondary development, file streaming and other technologies to develop a campus platform based on B / S architecture mode with both visualization, informatization, and cross-platform capabilities. This System platform designed the map display module, building BIM information query module, and then realize the sub functions of these modules.Through testing, the designed system works reliably and feasible to meet the needs of campus platform.
