Application analysis of drone oblique photography technology on railways
LI Weilin
Abstract：Taking a mountainous railway in southwestern China as the research object,this study deeply explores the application of unmanned aerial vehicle(UAV)oblique photogrammetry technology in railway projects,elaborates on the working principle and operation process of this technology,and combines it with its practical application in railway surveying.Through precision comparison and application analysis of the results,the practical experience is systematically summarized,and the significant advantages of this technology in railway projects are clarified.The research results indicate that this technology effectively solves the difficulties in surveying and mapping operations under the traditional railway surveying mode,improves the accuracy and efficiency of railway surveying,reduces field risks,and provides support for the efficient and high-quality promotion of railway surveying and design.
