三维激光扫描技术在建筑立面数字化采集和立面绘制方向应用的可行性研究

Feasibility study on the application of 3D laser scanning technology in the direction of building facade digital acquisition and elevation drawing

利用三维激光扫描技术可对建筑立面进行数据采集,通过对采集的三维点云数据进行拼接、去噪、提取等操作可得到完整的建筑立面点云数据。本文利用三维激光扫描仪快速获取了建筑立面数据,得到高精度的三维点云,将三维点云数据导入CAD中进行绘制,可以将建筑立面各个附属物件的位置、尺寸勾画清楚,保证立面图的准确性和可用性。

The three-dimensional(3 D) laser scanning technology is used to collect the data of the building facade. The complete point cloud data of the building facade can be obtained by splicing, denoising, and extracting the collected 3 D point cloud data. In this paper, the 3 D laser scanner is used to obtain the data of the building facade quickly, and obtain the high-precision 3 D point cloud. The position and size of each auxiliary object of the building facade can be drawn accurately and clearly by importing the 3 D point cloud data into CAD for drawing to ensure the accuracy and usability of the elevation drawing.
