Abstract

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

Key words: 3D laser scanning, building facade scanning, point cloud data, drawing accuracy of the point cloud data on building facade
