摘　　要：基于实现古建保护测绘建档工作提质增效的目的,采用了倾斜、贴近摄影和地面激光扫描等新型测绘技术在古建筑实施三维建模和建档测绘工作方法,以福州市闽侯闽清两县古建筑简略测绘建档为例,简要介绍了基于该方法古建筑采集要点、数据处理方法、点云配准融合和基于点云切面实施平立剖绘制的全过程,分析了所生成的测绘图件长度变形的误差情况。结果表明,该方法在建档测绘工作中的效果、效率和精度上有明显的提升,并能为古建筑的保护性修缮及旅游开发管理提供良好的数据服务。Based on the purpose of improving the quality and efficiency of the mapping and filing of ancient architecture protection,new surveying and mapping technologies such as oblique,nap-of-the-object photogrammetry and terrestrial 3D laser scanning are adopted to implement the three-dimensional modeling and archiving mapping method in ancient architecture.Taking the brief mapping and archiving of ancient architecture in Minhou and Minqing counties of Fuzhou as an example,this paper briefly introduces the key points of ancient architecture information collection,data processing methods and the whole process of point cloud registration fusion and plane vertical section drawing based on point cloud section,and the error of the length deformation of the generated mapping map is analyzed.The results show that this method has significantly improved the effect,efficiency and accuracy of archival surveying and mapping,and can provide good data services for the protective repair of ancient architecture and tourism development management.
