基于无人机LiDAR数据在公路勘测中的应用分析
|
摘要
随着电子、传感器与低空无人机技术的快速发展,轻小型、集成化的无人机LiDAR系统成为研究的热点,且无人机搭载LiDAR系统的数据获取、数据处理、点云配准与滤波及应用技术水平在不断的发展与完善。无人机飞行平台以起降条件简易、航空管制少及天气条件影响较小等优点,有效地弥补有人机搭载LiDAR测量系统平台的不足。本文结合广东东部山区、植被茂密区的某公路勘测项目,对采用无人机搭载LiDAR设备的数据获取、处理、精度验证等几个方面进行分析与总结,以期无人机搭载LiDAR设备的技术得到广泛推广与应用。
With the rapid development of electronic,sensor and low altitude unmanned aerial vehicle technology,light and small,integrated UAV LiDAR system has become a hot topic of research,and the UAV which equipped with the LiDAR system of data acquisition,data processing,point cloud registration and filtering and application technology is being developed and improved continuously quite recently. With the advantages of simple landing conditions,less air traffic control and less impact on the weather conditions and so on was applied UAV flight platform to make up for the shortage of manned aircraft platform LiDAR measurement system. In this paper,a certain highway survey project in the mountainous and dense vegetation area of Eastern Guangdong,it analyzes and summarizes the data acquisition,data processing,data precision verification and other aspects of the UAV equipped with LiDAR equipment,In order to this technology has been widely popularized and applied.
