Application Of UAV Tilt Photography In Mine Ecological Restoration

With the continuous promotion of mine ecological restoration in China,the traditional topographic survey method has exposed many limitations.With the advantages of flexibility,high efficiency and low cost,UAV tilt photogrammetry technology makes up for the shortage of topographic data survey and processing.This paper takes lijiaxiang Xinmao mine in Changxing County as the research object,introduces the UAV tilt photogrammetry technology in the early stage survey,scheme design and vegetation monitoring of the restored mine,and explores the application method of UAV tilt photogrammetry technology in the whole process of mine ecological restoration.First of all,based on the study of the traditional mine survey methods and the application status of UAV tilt photogrammetry,this paper finds that UAV tilt photogrammetry technology has strong feasibility in mine ecological restoration,which can effectively reduce the labor cost and time consumption,and facilitate the processing of data.Secondly,through the integration of tilt photogrammetry technology and geospatial information technology,the height analysis,slope analysis and slope texture analysis of the exposed slope of Xinmao mine are carried out,which provides data basis and optimization basis for the design of the bare rock green restoration scheme of the exposed slope of Xinmao mine.At the same time,the vegetation coverage,diversity and distribution of Xinmao mine have been monitored to complete the evaluation of vegetation restoration.Thirdly,the application process and method of UAV tilt photography in mine ecological restoration are described in detail through multi-stage terrain survey,data analysis,scheme design,process monitoring,development deepening and later management.Finally,the advantages of UAV tilt photography in mine ecological restoration and the prospect of its application in slope ecological restoration are summarized.
