Abstract：To meet the actual requirements of mine ecological restoration projects and achieve accurate and efficient investigations of restoration areas,this article takes the ecological restoration project of Fushun West Open-pit Mine as an exemple.Unmanned aerial vehicles(UAV)equipped with high-definition cameras are employed to collect aerial tilt images,while PIX4D software is utilized to construct three-dimensional models of the mine's ecological restoration areas.By assigning value to each collection spot within the ecological restoration area,the area of each block in the mine is accurately summarized,resulting in the identification of 16 distinct ecological restoration areas covering a total of 449 hectares.The results show that UAV tilt photography surveying and mapping technology has characteristics of high efficiency and convenience.The surveying and mapping results prove to be accurate and intuitive,effectively reducing the work intensity and playing a crucial role in the formulation of ecological restoration plans.
