Abstract：In order to improve the precision and collection efficiency of mine terrain data,based on UAV photogrammetry technology,this article explores the methods for terrain data acquisition and precision optimization in Baiyinhua No.1 Open-pit Coal Mine of Inner Mongolia.By establishing appropriate control points,planning flight routes and adjusting data processing parameters,the article adopts aerial triangulation densification and point cloud data precision analysis to improve data collection precision.The results show that the proposed systematic error compensation method and image data processing parameters optimized scheme effectively enhance the accuracy and reliability of mine terrain data,providing precise data support for earthwork calculations and engineering construction in mining projects.
