Abstract

Abstract: In order to reduce the workload of field survey in urban rail transit construction and improve the efficiency and accuracy of mapping, this study is based on an actual project. The SF1650 six rotor UAV LiDAR system is selected to aerial photograph of the Jinan East Railway Station area. The obtained LiDAR point cloud and image data are used to make DEM and DOM, and then large-scale topographic maps and sectional maps of the area are made. Through field surveys, it has been verified that the accuracy of DEM and DOM fully meets the requirements for large-scale topographic maps in urban rail transit construction projects. Compared to traditional stereomapping, the accuracy and data utilization have been greatly improved, greatly reducing the workload of field surveys. The feasibility of the SF1650 UAV LiDAR system has been verified, providing a reference plan for future engineering applications.
