BIM模型数据轻量化方法研究

摘要
设计一种轻量化的建筑信息模型(BIM)的文件结构(LBSF),该文件结构能与地理信息系统(GIS)有效集成,流畅展示复杂的BIM几何对象。近年来,基于GIS的城市设施管理研究增多,需使用GIS在园区甚至城市层面有效地可视化展示BIM几何对象,为此设计一种轻量级BIM数据结构并实现了原型系统。LBSF文件开发后,对数据量和加载性能进行比较,取得了较好效果。
Design a lightweight building information model(BIM) file structure(LBSF) that can work with gis(GIS) effective integration, smooth display of complex BIM geometric objects. In recent years, the research on urban facility management based on GIS has increased. It is necessary to use GIS to effectively visualize BIM geometric objects in the park or even in the city. For this reason, a lightweight BIM data structure is designed and a prototype system is implemented. After the LBSF file is developed, the data volume and loading performance are compared, and good results are obtained.
