Application of information remote sensing technology in oblique photogrammetry in mining surveying
In recent years,unmanned aerial vehicle(UAV)oblique photogrammetry technology has been widely used in the field of mining surveying due to its advantages of high efficiency,high accuracy,and low cost.This technology is based on a multi view camera device carried by drones,which captures images with a certain degree of overlap,and then uses optical principles and 3D reconstruction algorithms to generate accurate terrain and landform models of the mining area.The accuracy standard of data collection is crucial in the measurement process,as it directly affects the reliability of the final result.Drone measurement is applied in various aspects such as terrain reconstruction in mining areas,volume calculation of mining areas,slope stability analysis,environmental impact assessment,and post exploration stage detection.However,improving measurement efficiency and dealing with complex environments are still the main research directions at present.
