摘要:

BIM模型的创建是实现BIM技术应用的第一步,常见的基于CAD图纸的BIM模型创建方法存在建模效率低、空间表现不直观的缺点。本文以某地下人防工程的BIM模型重建为例,结合三维激光扫描技术,详细阐述了基于三维激光点云数据的BIM模型重建过程,主要步骤为:①利用FARO Focus3DX330获取海量点云数据;②利用FARO SCENE软件完成点云数据的配准拼接,滤波去噪,贴图输出;③按目标对象几何形状和功能特征的差异,利用Autodesk Revit分别完成线性类、构件连接类、单体目标类点云对象的BIM模型制作。研究表明,利用三维激光扫描技术可以很好地完成BIM模型的重建,而且具有建模精度高、现场还原度好的优势。

Abstract:

The creation of BIM model is the first step to the application of the BIM technology. The common method of BIM model creation based on CAD drawing has the disadvantages of low modeling efficiency and terrible spatial performance. Taking the reconstruction of BIM model of an underground civil defense engineering as an example, and combining with 3D laser scanning technology, the BIM model reconstruction process based on 3D laser point cloud data is elaborated, mainly through the following steps. First using FARO Focus3DX330 to obtain massive point cloud data. Then using FARO SCENE software to complete registration and splicing, filtering and denoising, texture and output. At last according to the differences in the geometric shapes and the functional characteristics of target objects, completing the BIM model reconstruction of linear class, component connection class, and single target class respectively by using Autodesk Revit. The research shows that the reconstruction of BIM model can be completed well by using 3D laser scanning technology, which has the prominent advantages of high modeling accuracy and good field reduction.

Key words: 3D laser scanning, point cloud data, underground civil defense engineering, BIM model
