摘要
Abstract
3D laser scanning technology has an incomparable technical advantage in the surveying and mapping of irregular building surface ar-ea,which can obtain the point cloud data of irregular building surface quickly and accurately.Taking Yiwu Meihu sports center gymnasium proj-ect for example,we systematically studied the key technologies such as laser point cloud data acquisition,data registration,model packaging and surface area calculation.While realizing the surveying and mapping of irregular building surface area,we proposed a new idea of classifying and calculating irregular building surface area by color,and evaluated the accuracy of surveying and mapping results.The calculation result shows that the root mean square difference of point plane of 3D point cloud model is±0.04 m and the gross error rate is 3.3%.The root mean square dif-ference of side length of 3D point cloud model is±0.03 m and the gross error rate is 0.0%.The data results are in line with the relevant standards of digital topographic map surveying and mapping.The research and analysis results show that it is feasible to use 3D laser scanning technology to survey the surface area of irregular buildings,which has certain theoretical significance and application value.关键词
