Application of UAV inclined photogrammetry in comprehensive ecological restoration of subsidence area above goafs
In order to obtain aerial photographic images for the comprehensive ecological restoration of 51101 working face subsidence area above goafs of Guojiawan Coal Mine,the UAV equipped with a five-lens tilt camera was used,and after internal processing and 3D modeling,the real 3D model was obtained.According to the precision analysis of the image control points and 3D model,the UAV inclined photogrammetry fully meets the mapping requirements of large-scale topographic map for coal mine management.With the real-life 3D model and the generated high-precision DLG data results,designers can accurately and efficiently put forward the corresponding ecological management method for the subsidence area,which greatly improves the pertinence and efficiency of the collapse management and land reclamation work,and provides accurate and trustworthy technical support and results verification for the later acceptance of the project,and ultimately effectively solves the problems of surface deformation and ecological damage in the management area.
