Analysis of Mine Change Using 3D Spatial Information Based on Drone Image

Mine development requires continuous management because it causes rapid topographic changes and environmental damage. Drones can be used to produce three-dimensional spatial information by quickly accurately photographing areas that are difficult or dangerous for humans approach. In this study, we investigated the possibility of using drone photogrammetry determining recovery in mines. The accuracy results was analyzed checkpoints, earthwork volume calculated compared with obtained through a field survey. We determined whether were consistent mountain plan images. RMSE 0.085–0.091 m plane 0.121–0.128 along elevation, as analyzing checkpoint creating an orthoimage digital surface model based on images; these satisfy tolerance range 1/1000 map descriptions. generated average error 11.9% conventional measurement method. use proved confirming vegetation rock prevention nets photographed usability mines is expected increase if substantial produced future.
