摘　　要：本文结合济南至青岛高速公路改扩建勘测项目,基于LiDAR的高速公路改扩建勘测关键技术进行了深入研究,提出了利用直升机搭载LiDAR设备进行点云数据获取,并基于地面靶标控制点对点云数据进行高精度纠正,经过试验得出了靶标控制点布设的最佳间距,形成了基于LiDAR技术的高速公路改扩建勘测技术方案,以供同类项目借鉴参考。This paper takes the project of Ji＇nan Qingdao expressway extension survey for example,making a in-depthresearch on the key technology of expressway extension survey based on LiDAR.And putting forward the use of helicopters equipped with LiDAR system to obtain point cloud data.Then using ground target control points to correct the point cloud data.After experiments,arriving the best spacing of ground target control points,and forming the technical scheme of expressway reconstruction and extension survey based on LiDAR technology,and it will provide some useful reference for similar projects.
