有人机机载LiDAR在新建文蒙铁路勘测中的应用分析

Application Analysis of Manned Airborne LiDAR in the Survey of the New Wenmeng Railway

为解决云南省东南部文蒙铁路沿线地势起伏不定,无法测量详实、准确的数据资料,满足新建铁路勘察设计需要的问题,提出有人机机载LiDAR在新建文蒙铁路勘测中的应用研究。利用机载LiDAR采集点云数据,预处理新建铁路点云数据,生成新建铁路的点云图像。以航摄分区为基础确定航高并敷设航线,通过设计机载雷达等相关参数完成新建铁路轨道勘察。

In order to solve the problem that the terrain along the Wen-Mongolian Railway in southeastern Yunnan is undulating,and it is impossible to measure detailed and accurate data,so as to meet the needs of the survey and design of the new railway,the application research of manned and airborne LiDAR in the survey of the new Wen-Mongolian railway is proposed.The airborne LiDAR is used to collect point cloud data,preprocess the point cloud data of the newly built railway,and generate the point cloud image of the newly built railway.Determine the flight height and lay the route based on the aerial photography zoning,and complete the survey of the newly built railway track by designing the airborne radar and other related parameters.
