摘要:三维激光扫描技术可以利用高速激光,快速获取被测实体表面的三维坐标。通过对点云数据的配准、降噪,可以进一步构建反映实际建造效果的点云模型。将点云模型与BIM设计模型进行对比,则可以得到施工过程中产生的尺寸及位置偏差,从而可以进一步指导后续的施工过程或者设计变更。本文的创新点在于:提出了一整套点云模型与BIM模型的对比方法,并借用WebGL技术实现了对比结果的可视化。
Abstract: 3D laser scanning technology can use high-speed laser to quickly obtain the three-dimensional coordinate data of the object surface. Through registration and filter of point cloud data, a point cloud model reflecting the actual construction effect can be further constructed. By comparing the point cloud model with the BIM design model, the dimensional and position deviations generated during the construction process will show up, which can further direct the subsequent construction process or design changes. Based on BIM technology and 3D laser scanning technology, this paper proposes a set of theoretical comparison methods between point cloud model and BIM model, and uses WebGL technology to realize the visualization of the comparison results.
