Abstract: Based on the difficulties in data acquisition,low accuracy,and lack of three-dimensional information in the process of ecological restoration in abandoned mines,this paper proposes a set of dynamic supervision methods for ecological restoration in abandoned mines based on real-life 3D scenarios. Firstly,UAV oblique photogrammetry is carried out for abandoned mines,and after processing,the DEM and DOM are obtained,and a realistic 3D model is established. Secondly,based on key technologies such as earthwork calculation,change detection,and supervised classification,ecological restoration parameters are extracted. Finally,using real-life 3D models and ecological restoration parameters,effectively monitor the engineering quantity and compliance of geological environment protection,terrain reshaping,vegetation reconstruction,and land reuse projects. The results indicate that based on realistic 3D,it is possible to timely obtain the changes in abandoned mines,assist in formulating more refined restoration plans,effectively monitor the effectiveness of ecological restoration,and update realistic 3D data,which is of great significance for realizing the application value of realistic 3D.
