Abstract
At present, total station or gnss-rtk is often used in mine ecological environment restoration survey, which has the disadvantages of high intensity, long cycle and high cost. In particular, the problems of landslide and collapse in abandoned mines bring potential safety hazards to the surveying and mapping personnel. The traditional surveying and mapping results are 2D graphics, and the information of topography and geological disasters is not intuitive, which brings inconvenience to the design of ecological environment restoration scheme. In order to meet the actual needs of mine ecological restoration, UAV incline photogrammetry technology is applied in the survey and mapping, scheme design and construction management stages of mine ecological environment restoration. The research results show that UAV incline photogrammetry technology can realize: ensure the safety of technical personnel, make the survey and mapping more efficient; make the mine environment information more intuitive, vivid and vivid, which is conducive to the formulation of ecological restoration plan, dynamic grasp of construction progress, and make mine ecological restoration more accurate.
