摘　　要：传统方法对空洞和缺失点云的修复不到位,缺乏空间细节深度信息,导致建筑空间重建精度较差。为此,提出基于激光散射测量的虚拟建筑空间重建方法。利用激光散射测量技术,采集能够表现建筑三维坐标的点云数据,拼接多视角点云,并进行去噪分割处理,建立建筑空间主平面模型,内插填补边缘信息和细节深度信息,实现虚拟建筑空间重建。进行对比实验,完成形态相似规则的住宅楼重建工作,结果表明,此次设计方法相比传统方法,提高了点云数据去噪效果及拼接精度,减小了建模距离与实测距离偏差,提高了建筑空间重建精度。The traditional methods of repairing holes and missing point clouds are not in place,and lack of depth information of spatial details,resulting in poor accuracy of building space reconstruction.Therefore,a virtual building space reconstruction method based on laser scattering measurement is proposed.The laser scattering measurement technology is used to collect the point cloud data which can show the three-dimensional coordinates of the building,splice the multi view point cloud,and carry out the denoising and segmentation processing.The main plane model of the building space is established,and the edge information and detail depth information are interpolated to realize the virtual building space reconstruction.Compared with the traditional method,this design method improves the denoising effect and splicing accuracy of point cloud data,and the deviation between the modeling distance and the measured distance is the smallest,which improves the accuracy of building space reconstruction.
