基于无人机的矿区地表水平移动监测方法
Horizontal Movement Monitoring Method of Mine Surface Based on UAV
摘要
Abstract
In order to more comprehensively monitor the surface deformation of mine caused by mining,we proposed a horizontal movement monitoring method of mine surface based on UAV photogrammetry technology.Firstly,we used UAV to obtain time-series aerial images of multi-stage monitoring areas.Then,we used Pix4Dmapper to process images,and obtained time-series DOM of monitoring areas.We used the feature point matching method to match the position of same feature points on the DOM of different periods,so as to calculate the displacement and movement direction of feature points.Finally,we drew a horizontal movement time-series vector displacement map.This method has been applied to a working face of Nantun coal mine in Jining City,Shandong Province.The monitoring accuracy is 3.8 cm when UAV image resolu-tion is 2.73 cm/pixel,which can reflect the horizontal movement trend and provide data support for underground mining,cultivated land protection and ground relocation.关键词
