摘　　要：室内外一体化的建筑物模型是智慧城市管理的基础数据,倾斜摄影和地面三维激光扫描是当下两种主要的建筑物模型数据获取方式。针对单一数据采集方式受诸多因素制约,难以获取完整建筑物室内外三维数据的难题,本文提出了倾斜密集匹配点云与地面激光扫描点云融合的技术路线,利用地面激光扫描获取建筑物立面与室内点云,利用倾斜摄影获取建筑物顶部点云,并将两者结合构建室内外一体化的完整建筑物点云;以高密泥塑展馆为研究对象,验证了该技术路线的可行性及融合精度,可为类似项目提供参考。Indoor and outdoor integrated building model is the basic data of smart city management.Tilt photography and ground 3D laser scanning are the two main ways to obtain building model data.In view of the problem that a single data acquisition method is restricted by many factors and it is difficult to obtain complete indoor and outdoor 3D data of buildings,this paper puts forward the technical route of the integration of tilt dense matching point cloud and ground laser scanning point cloud.This route uses ground laser scanning to obtain the building facade and indoor point cloud,and tilt photography to obtain the building top point cloud.The two combine to build a complete indoor and outdoor integrated building point cloud.Taking the Gaomi clay sculpture exhibition hall as the research object,this paper tests the feasibility of the above technical route and verifies the fusion accuracy,which can provide reference for similar projects.
