摘　　要：为了解决提取寿县古城墙的鼓包病害信息的问题,利用地面激光扫描技术(TLS)以及Geomagic Studio软件处理的方法。TLS技术通过发射和接收激光束来测量距离,记录激光激发过程中的角度,生成大量空间点的数据集,形成详细的三维模型,再通过软件进行点云切片和采样方法,提取和可视化寿县古城墙的鼓包病害特征。由此得到寿县古城墙的鼓包凸出区域主要集中在城墙的顶部,并且所有的凸起都是从顶部向下扩展的结果。得出该方法能准确反映寿县古城墙的鼓包实际情况的结论。研究表明,运用TLS为古建筑病害检测提供了有效手段,并具有推广应用于其他类型墙体的潜力。In order to solve the problem of extracting bulging disease information from the ancient city walls of Shouxian,ground laser scanning technology(TLS)and Geomagic Studio software processing methods were used.TLS technology measures distance by emitting and receiving laser beams,records angles during laser excitation,generates a large dataset of spatial points,forms detailed 3D models,and then uses software for point cloud slicing and sampling methods to extract and visualize the bulging disease characteristics of the ancient city walls in Shouxian.Using this method,it is found that the bulging areas of the ancient city wall in Shouxian are mainly concentrated at the top of the wall,and all the protrusions are the result of expanding downwards from the top.The conclusion is that this method can accurately reflect the actual situation of bulging on the ancient city walls of Shouxian.Research has shown that this method provides an effective means for detecting diseases in ancient buildings and has the potential to be widely applied to other types of walls.
