Application Research on Mine Restoration Survey Based on Oblique Photogrammetry
In order to analyze and evaluate the process of land reclamation and ecological environment restoration in the mining area, this paper takes aerial photography of a mining area based on the UAV oblique photogrammetry technology, and obtains the realistic 3D model of the mining area in the same month in the past three years. The land use type classification process is carried out, and the land use type coverage map is obtained, so as to comprehensively evaluate the ecological environment restoration degree of the mining area in the past three years, and comprehensively verify the evaluation results by on-site investigation, so as to provide reliable data support for the direction of land reclamation in the mining area. The results show that the three-dimensional realistic model construc-ted by oblique photogrammetry has high accuracy and can meet the needs of ecological environment restoration evaluation in mining ar-eas, and the monitoring results of ecological environment restoration have a relatively high agreement with the actual changes in the re-gion, which can effectively guide the direction of ecological environment restoration in mining areas.
