摘　　要：高速公路改造施工前需要精确测量公路横断面,传统测量方法效率低、安全性差。针对以上问题,运用车载移动测量技术开展高速公路纵横断面提取方法研究,设计详细的数据采集方案和点云数据预处理方式,优化多软件融合的公路纵横断面特征采集技术,实现了车载移动测量公路纵横断面高精度批量化提取。以G25高速连云港至淮安段改扩建工程为例进行分析,结果表明,车载移动测量系统采集的纵横路面点云高程与RTK实测高程差异优于±1.77 cm,能为高速公路改扩建提供可靠的纵横断面数据基准,极大提高了公路测量效率。It is necessary to measure the cross and vertical section of highway accurately before its reconstruction,the traditional measurement method has low efficiency and poor safety.In view of the above problems,this paper studies the extraction method of highway cross section based on vehicle-mounted mobile measurement technology.The data acquisition scheme and point cloud data preprocessing method are design detailed,the multi-software combination of highway cross and vertical section acquisition technology is constructed,and the high-precision mass extraction of highway cross and vertical section based on vehicle-mounted mobile measurement system is realized.Taking the reconstruction and expansion project of G25expressway from Lianyungang to Huai'an as an example,the analysis results show that the difference between the point cloud elevation of the cross and vertical section collected by the MMS and the measured elevation of the RTK is less than±1.77cm,which can provide reliable data reference for the cross and vertical section of the expressway reconstruction and expansion,and greatly improve the efficiency of highway measurement.
