Abstract

Abstract: On the basis of analyzing the current application status of UAV aerial surveying and remote sensing technology,this article classifies and summarizes the technology. Taking the Baotian section of the Longhai Railway as a case study,the application and technical advantages of UAV aerial surveying and remote sensing technology are detailed from four aspects: UAV aerial surveying and mapping,UAV LiDAR existing railway resurveying,UAV 3D modeling and LiDAR point cloud assisted geological hazard analysis,and UAV aerial photography assisted investigation. Summarize the current shortcomings of this technology in terms of operational efficiency,intelligence level,absolute accuracy,etc. At the same time,it is believed that hardware development,data processing,and expanded applications are the main development directions for its future.The UAV remote sensing technology system adopted in this article can provide technical reference and guidance for the survey and design of similar mountainous railways.

Key words: UAV, oblique photography, LiDAR, aerial photography, quality improvement and renovation
