随着机载LiDAR技术的快速发展,机载LiDAR技术在公路勘测阶段的应用也在近几年逐步的发展起来。本文主要介绍了利用机载LiDAR技术,快速的获取地处地势复杂的云南蒙文砚高速公路的点云数据,并通过控制点检验点云数据的精度,数字高程模型DEM与影像数据。在项目实施过工程中取得了丰富的实验数据和经验,为机载LiDAR技术在公路方面的推广应用起到重要的作用。
With the rapid development of on-board LiDAR technology, the application of on-board LiDAR technology in the highway survey stage has been gradually developed in recent years. This paper mainly introduces the use of on-board LiDAR technology to quickly obtain the point cloud data of Yunnan Mengwenyan expressway with complex terrain and verify the accuracy of point cloud data and digital elevation model DEM and image data through control points. In the project implementation project has made a wealth of experimental data and experience for the promotion of airborne LiDAR technology plays an important role in the road.
