摘要
Abstract
This paper mainly explores the application of three-dimensional laser scanning system in the slope deformation monitoring of a goaf,and calculates and analyzes the point accuracy of the slope model.The Maptek I-Site 3D laser scanner is used to collect the slope point cloud data,and the matching Maptek I-Site Studio software is used to splice,filter and simplify the point cloud data,and the simplified point cloud data is used to construct the slope surface model.Taking the target coordinate data obtained by the total station as the standard value and the target coordinate data obtained by the three-dimensional laser scanner as the measured value,the true error between them is obtained,and then the point median error of the observed value is obtained.The results show that the point accuracy measured by the three-dimensional laser scanning system is Level IV,which can only meet the accuracy requirements of horizontal displacement monitoring of soil slope.关键词
