摘　　要：三维激光扫描技术具有非接触式测量、速度快、精度高、真实感强等特点,已被广泛应用于古建筑测绘建档及修缮保护。本文基于三维激光扫描技术,利用点云数据在古建筑测绘建档与结构变形进行了分析和研究,以宗兴堂为例,提出了古建筑测绘建档从数据获取到档案成果编制的技术流程,并对一进厅堂立柱的偏移方向及倾斜度进行了分析,结果表明:一进厅堂存在北偏东倾斜趋势。为后续古建筑修缮方案提供可靠、真实的基础数据。3D laser scanning technology has the characteristics of non-contact measurement,high speed,high accuracy and strong sense of reality,which has been widely used in ancient building surveying and mapping,archiving,repair and protection.Based on the 3D laser scanning technology,this paper analyzes and studies the archiving and structural deformation of ancient buildings by using point cloud data.Taking Zongxingtang as an example,the paper puts forward the technical process of the ancient building archiving by surveying and mapping from data acquisition to the compilation of archives results,and analyzes the deviation direction and inclination of the columns in the first hall.The results show that there is a tendency of north to east inclination in the first hall,It can provide reliable and real basic data for the follow-up repair scheme of ancient buildings.
