摘要
传统的公路改扩建工程主要采用水准仪、全站仪或RTK等测量方法联测得到数据。针对传统测量方法工作量大、效率低、干扰正常交通秩序等问题,采用车载激光扫描测量系统,可快速获得路面点坐标信息及道路两侧情况。本文结合项目实际,通过车载激光扫描技术在公路改扩建测绘的应用研究,建立了完整的技术流程,生成具有三维地理空间坐标的激光点云和全景影像,并通过道路线和路面点提取,得到符合精度要求的道路信息和路面特征点的坐标和高程。
Traditional highway reconstruction and expansion projects mainly use leveling,total station or RTK measurement methods to get data.Aiming at the problems of heavy workload,low efficiency and disturbance to normal traffic order of traditional measurement methods,the vehicle laser scanning measurement system can quickly obtain the coordinate information of road points and the situation on both sides of the road.Combined with the project reality,through the application research of vehicle-borne laser scanning technology in highway reconstruction and extension mapping,this paper establishes a complete technical process,generates laser point cloud and panoramic image with three-dimensional geospatial coordinates,and obtains road information and coordinates and elevation of road characteristic points which meet the accuracy requirements by extracting road lines and road surface points.
