摘要
为了减少轨道交通建设外业勘测的工作量,提高制图的效率和精度,本文首先基于实际项目,选用智航SF1650六旋翼无人机载LiDAR系统对济南新东站片区进行航摄,利用获取的LiDAR点云和影像数据制作DEM、DOM,然后再进行大比例尺地形图和片区断面图的制作。通过外业勘测核实,DEM和DOM精度完全满足轨道交通建设工程制作大比例尺地形图的要求,且相较于传统立体航测,精度和数据利用率得到很大的提升,极大减少了外业勘测工作量,验证了智航SF1650无人机载LiDAR系统的可行性,为今后的工程应用提供了参考方案。
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.
