摘　　要：针对虎丘塔古建筑存在损坏等情况,本文通过虚拟修复对其进行保护,首先利用三维激光扫描仪进行数据采集获得虎丘塔的点云数据,再根据邻域相似原则对古建筑破损部位进行虚拟修复,使用Faro Scene和Geomagic Qualify对虎丘塔点云数据进行配准和去噪,最后通过切片和最小二乘拟合方法将选中的几何块绕旋转中心旋转一定角度进行虚拟修复。实验结果表明,在三维平面上误差在-0.0132~0.0132 m的点云为97.53%。本文方法精度较高能够有效修复破损的虎丘塔,可以为其他古建筑的保护提供一定的借鉴意义。In view of the damage of the ancient building of Tiger Hill Tower,this paper proposed a method through virtual repair,first used three-dimensional(3D)laser scanner for data collection to obtain the point cloud data of Tiger Hill Tower,and then virtually repairs the damaged part of the ancient building according to the principle of neighborhood similarity,applied Faro Scene and Geomagic Qualify to register and denoise the point cloud data of Tiger Hill Tower.Finally rotates the selected geometric blocked around the rotation center by slicing and least squares fitting method for virtual repair.The experimental results showed that the point cloud with an error of -0.0132~0.0132 m in the three-dimensional plane was 97.53%.The high precision of the method in this paper could effectively repair the damaged Tiger Hill Pagoda,which could provide certain reference significance for the protection of other ancient buildings.
