摘　　要：针对三维激光扫描技术在数据获取中存在数据缺失的问题,提出利用无人机航摄技术弥补三维激光扫描数据缺失,进而实现古建筑三维建模的方法。选定辽宁省鞍山市千山风景区香岩寺天王殿古建筑为实验目标,利用三维激光扫描仪和无人机分别对目标体采集数据,对三维激光扫描仪获取的点云数据进行点云去噪、重采样和配准,将处理后的点云数据与处理后的无人机获取影像数据进行融合,最终获得该古建筑三维模型。实验结果表明,基于点云数据和影像数据融合建模,模型纹理清晰,几何结构完整,获得较为理想的三维建模效果。Aiming at the problem of missing data in data acquisition of 3D laser scanning technology,this paper proposes a method of using UAV aerial photography technology to make up for missing data in 3D laser scanning,and then realize 3D real scene modeling of ancient buildings. An ancient building of Hall of Heavenly Kings in Rock Temple were selected as the studying target,which is located in Qianshan scenic area of Anshan city,Liaoning province. Data were collected from the target using 3D laser scanner and UAV. After denoising,resampling,and registration,the point cloud data obtained by 3D laser scanner were fused with the processed image data obtained by UAV to finally obtain a three-dimensional model of the ancient building.The experimental results show that the model based on fusion of point cloud data and image data exhibits clear texture and complete geometric structure,ensuring ideal 3D real scene modeling effect.
