Abstract
With the rapid development of UAVs,LiDAR mounted on UAVs has gradually become the main equipment for mine measurement work due to its high efficiency,high accuracy and strong applicability.This paper describes the application accuracy of UAV mounted LiDAR in mine surveys,and discusses the feasibility of UAV mounted LiDAR on different terrains and landforms.And through application cases,the application effect of UAV equipped LiDAR measurement technology in terrain mine measurement,mine reserve estimation,and mine safety monitoring is presented.The accuracy of the point cloud data obtained during the UAV mounted LiDAR measurement is analyzed through trial data.The parameters such as the horizontal accuracy of point cloud density,vertical accuracy of point cloud density,and plane accuracy of point cloud density are analyzed,and are compared with our routine acquisition.The measurement methods of point cloud are compared.The author believes that UAVs equipped with LiDAR have great advantages in mine measurement.It can quickly obtain three-dimensional geological information,which is conducive to the management of mine resources,environmental monitoring and natural disaster prediction.It will play a laying and guiding role in better promoting and applying UAV mounted LiDAR in mine surveying in the future.关键词
