将三维激光扫描技术的高精度、高分辨率与建筑信息模型(building information modeling,BIM)技术的构件及建模特性相结合，应用于历史建筑测绘建档，能有效发挥两种技术的优势。首先通过三维激光扫描技术获取要进行测绘建档的历史建筑的三维几何信息，得到点云模型，然后根据点云模型的尺寸信息建立 BIM 模型，最后实现历史建筑的测绘建档。文章研究内容旨在为历史建筑修复施工、维护、监测及信息存档提供技术支持。

Combining the high precision and high resolu- tion of 3D laser scanning technology with the components and modeling characteristics of the Building Information Modeling (BIM) technology, and applying it to the sur- veying, mapping and archiving of historical buildings, the advantages of the two technologies can be effectively utilized. Firstly, the 3D geometric information of the his- torical buildings to be surveyed, mapped and archived is obtained by 3D laser scanning technology, and the point cloud model is obtained. Then, the BIM model is built ac- cording to the dimensional information of the point cloud model. Finally, the surveying, mapping and archiving of the historical buildings is realized. The research content aims to provide technical support for the restoration con- struction, maintenance, monitoring and information ar- chiving of historical buildings.
