Abstract:

The application of 3D laser scanning technology is becoming more and more widespread in current society. However, due to the large amount of point cloud data, how to reconstruct and identify a large number of point cloud data quickly and efficiently is the key to solve the problem. The point cloud segmentation technology can separate the feature information in the facade point cloud from the background point cloud, providing important technical support for the extraction and identification of feature information. In this paper, a variety of point cloud segmentation algorithms are programmed to segment the facades of buildings, and the segmentation accuracy and applicable range of different algorithms are analyzed in detail.
