无人机影像支持的矿区开采动态监测方法

ue to the unreasonable development and utilization of the mining area, the mining area environmental problems are particularly prominent. And the dynamic monitoring of the mining area can effectively reduce the negative impact of mining activities. Traditional mine environmental monitoring adopts field inspection and step-by-step reporting, which requires not only a great deal of manpower, material and time, but also a timely response to problems, so it is necessary to find a way to meet the current mine monitoring required method. In this paper, the unmanned aerial vehicle (UAV) is used to acquire the high spatial resolution image of a mining area for dynamic monitoring of mining area. The images were processed by Structure from Motion of Agisoft PhotoScan Pro software, which realized the fast mosaic of images and the rapid generation of digital elevation model and digital orthophoto map. Finally, using Arcgis software GIS method to obtain the DEM elevation changes in different periods and the amount of fill and excavation, to achieve dynamic monitoring of mining area. The results of the study are objective, which can provide effective data for the relevant departments of the mining area to manage and plan the exploitation status of the mining area.
