摘　　要：针对古建筑BIM各种信息模型中几何模型构建的问题,提出应用三维激光点云数据和CloudWorx软件进行建模的方法。应用Cyclone软件对点云数据进行去噪、配准,按构件进行分割;应用CloudWorx软件进行模型的构建。研究古建筑的瓦片、柱体、梁、墙体、围栏等构件的建模方法,通过模型合并生成古建筑的整体几何模型。For the construction of geometric model of ancient buildings BIM, this paper provlaes a moueiling method using 3D laser point cloud data and CloudWorx software. First, a point cloud model is built according to the denoising and registration, and then, segmentation by the component is imposed by using Cyclone software. Second, CloudWorx software is used to build surface model, which is focused on the modeling method of ancient architectural tiles, column, beam, wall and fencing. Finally, taking an ancient building point cloud model as an example, the whole geometry model of ancient architecture is generated.
