城市级实景三维与BIM集成技术研究与实践

Research and Practice of Integration Technology of City-Level Real 3D and BIM

针对实景三维与建筑信息模型(building information model,BIM)集成中面临的数据格式多样、坐标体系不一、数据体量巨大和空间组织繁杂等诸多问题,结合深圳市实践,提出了BIM标准、坐标转换、模型轻量化和模型组织调度等关键技术,并在工程实践中验证了可行性。

To solve the problems in the integration of real 3D and building information model(BIM)such as diversified data format,different coordinate systems,huge data volume and complex spatial organization,we propose some key technologies such as BIM standards,coordinate conversion,the lightweighting of models and organization and scheduling of models based on the practice in Shenzhen.Their feasibilities are verified in the engineering practice.
