摘要
工程建设项目“多测合一”旨在实现“联合测绘、成果共享”,助力优化营商环境。异形建筑结构复杂多变,使用传统测量方法工作效率低,且限飞区无法开展航空摄影,文中构建一套基于车载-站式点云数据融合的限飞区异形建筑室内外一体化建模和“多测合一”技术体系,通过建立异形建筑高精度竣工BIM模型,实现面积计算、立面图、现状地形图成图等“多测合一”工作。并以广州白云国际机场T2航站楼项目实际验证,该方法精度符合相关规范要求。
“Multi-measurement Integration”of engineering construction projects aims to achieve“joint surveying and mapping,result sharing”,and helps optimize the business environment.The structure of special-shapedbuildings is complex and variable.The traditional method has low measurement efficiency,and aerial photography cannot be carried out in no-fly zone.This paper constructs a set of technology systems for“Multi-measurement Integration”,indoor and outdoor integrated modeling of special-shaped buildings in no-fly zone based on the fusion of vehicle-mounted and stationary laser point cloud data.By establishing a high-precision as-built BIM model of special-shaped buildings in no-fly zones,it performs the“Multi-measurement Integration”work such as area calculation,elevation drawing,and current topographic mapping.Through the actual verification of the Guangzhou Baiyun International Airport Terminal 2 project,the accuracy of this method meets the relevant specification requirements.
