摘　　要：利用三维激光扫描技术在古建筑测绘中的辅助测绘优势,以福建省泰宁县全国重点文物保护单位之明代古建筑"尚书第"为例,进行3个层面关键技术问题研究:1)从点云数据的采集、点云数据的拼接、点云数据的去噪,到CAD图形的生成和三维空间影像生成等古建筑测绘及数据生成处理中的关键技术问题;2)针对三维激光扫描技术应用过程中产生的庞大数据量、古建筑构件的细部测绘难点等关键问题提出具体应对策略;3)基于传统测绘法比较研究验证三维激光扫描仪技术应用于斗栱梁架局部剖面测绘的实际效果。Taking the advantages of aided surveying of 3D laser scanning technology in measuring traditional architecture, this paper studies key technical problems on three levels in this field by using the example of surveying 'Shang Shu Di', a national protected heritage of Ming Dynasty in Taining County, Fujian Province. First, the key technical problem is data generation process from the point cloud data acquisition, the splicing of the point cloud data, the noise eliminating of point cloud data, to the generation of CAD graphics and the generation of 3D space image. Second, the paper proposes specific strategies to cope with the huge amount of data and CAD graphics conversion in the application of 3D laser scanning technology. Finally, the paper presents a comparative study and validation of the practical application results of 3D laser scanning technology used in the partial sectional mapping of bracket set and beam-column comparing with traditional surveying and mapping.
