基于三维激光扫描仪的矿区边坡变形监测数据的分析处理

以南郑县碑坝孔溪沟锌矿区边坡为研究对象,选用三维激光扫描仪采集边坡变形数据,对变形监测数据进行分析和处理,从而研究矿区边坡变形.针对点云数据拼接、点云滤波、点云精简、模型重建等数据处理过程中常遇到的问题,提出了相应的解决方法.提出了多边形分割法,将模型的重点关注区域划分为多个多边形,根据多边形重心坐标的变化分析了边坡的...

Analysis and processing of slope deformation monitoring data in mining area based on 3D laser scanner

Taking the slope of Kongxigou Zinc Mining Area in Beiba of Nanzheng County as the research object,3D laser scanner was selected to collect the slope deformation data,and the deformation monitoring data were analyzed and processed,so as to study the slope deformation of the mining area.Aiming at the problems often encountered in the process of data processing,such as point cloud data splicing,point cloud filtering,point cloud simplification and model reconstruction,this paper put forward some methods for reference.In addition,a polygon segmentation method was proposed to divide the focus area of the model into several polygons,and the horizontal and vertical displacement of the slope was analyzed according to the change of the coordinates of the polygon center of gravity.The results show that the analysis results of deformation monitoring data are consistent with the actual changes.
