激光雷达技术在露天煤矿征地外业调查中的应用

Application of Lidar technology in field investigation of land acquisition in open-pit coal mines

在我国加快发展数字经济和国有大型煤炭企业不断加大研发创新力度的背景下,针对鄂尔多斯地区露天煤矿征地外业调查面临的树木附着物过多、耗时过长的问题;基于激光雷达技术,利用无人机激光雷达系统获取拟征收区域树木附着物点云数据,通过LIDAR360软件对点云数据进行分析处理,最终获取树木的数量、高度、冠幅等征地外业调查核心数据;实现了征地外业调查过程的数字化、智能化,大幅缩短了征地进程,减少了因征地产生的纠纷,从而有效保障煤矿生产用地接续。

In the context of China's accelerated development of digital economy and the continuous increase of R&D innovation by large state-owned coal enterprises,aiming at the problems of excessive tree attachments and long time consumption in the field investigation of land acquisition in open-pit coal mines in the Ordos region,based on Lidar technology,this article used the UAV lidar system to obtain the point cloud data of tree attachments in the area to be expropriated,and then analyzed and processed the point cloud data with LIDAR360 software,finally obtaining the core data of land expropriation field survey such as the number of trees,height and crown width,which realized digitization and intelligentialize of land expropriation field survey,greatly shortened the process of land expropriation,reduced the disputes caused by land expropriation,and effectively guaranteed the continuation of coal mine production land.
