摘要
Abstract
The purpose of this paper is to explore the application of three-dimensional laser scanning technology to the safety appraisal of buildings,and to repeatedly detect the results of cracks and appearance defects of buildings based on laser point cloud by using traditional detection methods.verify the feasibility and reliability of laser point cloud detection of building surface cracks and appearance defects,provide technical guarantee for building physical examination of old urban buildings and self-built buildings,and find potential safety risks in time,to ensure the safety of people's lives and property.The results show that a total of 304 defects were found in 6 buildings in Nanning.Compared with the detection results of cracks and appearance defects detected by three-dimensional laser scanning technology,21 building defects were missed,and the error rate was 6.9%.关键词
