摘要
为了更好地监测矿区开采沉陷变形情况,提出一种基于无人机航测技术的矿区开采沉陷变形监测方法。优先标定相机,输入无人机畸变参数,降低相机畸变误差。通过无人机航测技术获取矿区影像数据,采用UASMaster软件对点云数据预处理。将倾斜航拍方案引入沉陷区,获取矿区地面无人机倾斜数据;采用矿区经验参数以及实际观测数据预测沉陷盆地,最终达到矿区开采沉陷变形监测的目的。仿真实验结果表明,所提方法可以获取高精度的矿区开采沉陷变形监测结果。
In order to better monitor the mining subsidence deformation in the mining area,a method for monitoring the mining subsidence deformation in the mining area based on UAV aerial survey technology is proposed.Give priority to camera calibration,input UAV distortion parameters,and reduce camera distortion error.The image data of the mining area is obtained through the aerial survey technology of unmanned aerial vehicles,and the point cloud data is preprocessed by the UASMaster software.The tilt aerial photography scheme is introduced into the subsidence area,and the tilt data of the ground drone in the mining area is obtained;the subsidence basin is predicted by the empirical parameters of the mining area and the actual observation data,and finally the purpose of monitoring the mining subsidence deformation of the mining area is achieved.The simulation results show that the proposed method can obtain high-precision monitoring results of mining subsidence deformation in mining areas.
