Research on building 3D reconstruction technology integrating UAV oblique photography and ground LiDAR
LAI Xianmei
Abstract：In response to the limitations of modeling using either UAV oblique photogrammetry or ground LiDAR alone,the article proposes a surveying method that integrates UAV oblique photogrammetry with ground LiDAR technology.This method obtains data of the tops of target buildings via UAV oblique photogrammetry and collects ground data using ground LiDAR.Through point cloud data fusion,it constructs a detailed three-dimensional model that is rich in texture and structurally complete.Experimental results show that this integration of technologies not only preserves the high-efficiency advantages of UAV oblique photogrammetry but also leverages the high-precision strength of ground LiDAR technology.The accuracy of the constructed model meets relevant standards,and the technology is suitable for digital reconstruction of complex building scenarios.
