精确、高效的机场跑道空间三维地理信息数据采集是实施HUD飞行程序的首要任务。针对传统机场环境空间三维地理信息数据采集技术的低效率、数据缺失严重等局限性,本文研究了基于三维激光LiDAR扫描技术的机场跑道地面基准快速测量方法,利用激光LiDAR获取的高精度、高密度机场跑道环境三维点云数据,构建高精度的机场环境数字表面模型(DTM),进行平面虚拟测量及纵断面等模型生成。以广州白云机场02R跑道为研究对象,通过试验分析表明三维激光LiDAR扫描技术能够高效、精准地获取地面基准的空间三维地理信息数据,为机场跑道空间设计管理提供全面的空间数据,对同类型的测量具有一定借鉴意义。

Accurate and efficient three-dimensional geographic data collection of airport runway space is the primary task of implementing HUD flight procedures.Aiming at the limitations of low-efficiency and serious data loss in traditional airport environment three-dimensional geographic information data collection technology,this paper studies the fast measurement method of airport runway ground reference based on three-dimensional laser LiDAR scanning technology,and uses laser LiDAR to obtain high-precision,high-density 3D point cloud data of the airport runway environment,which was used to construct a high-precision airport environment digital surface model(DTM),and plane virtual measurement and profile generation were performed.Taking the 02 R runway of Guangzhou Baiyun Airport as the research object,experimental analysis shows that the 3D laser LiDAR scanning technology can efficiently and accurately obtain the spatial 3D geographic information data of the ground reference,and provides comprehensive spatial data for airport runway space design management,which provides a certain reference for the same type of measurement.
