摘　　要：为满足路面大修工程对高精度横断面数据的需求,提出基于LiDAR的路面大修工程横断面测量方法。通过激光扫描设备获取原始点云数据,利用定位定向系统和BDP数据进行预处理和拼接,实现对路面横断面数据的分割和处理。通过测量中桩两侧地面坐标信息,确立横断面设计高程值,以此为依据将其以标准化的格式输出横断面测量成果数据。实验结果表明,该方法不易受环境因素影响,测量精度较高,为路面大修工程的设计施工提供准确数据支持,保证了道路设计符合交通安全要求。To meet the demand for high-precision cross-sectional data in pavement overhaul engineering,a LiDAR based cross-sectional measurement method for pavement overhaul engineering is proposed.Obtain raw point cloud data through laser scanning equipment,preprocess and concatenate it using positioning and orientation systems and BDP data,and achieve segmentation and processing of road cross-section data.By measuring the ground coordinate information on both sides of the central pile,establish the design elevation value of the cross-section,and based on this,output the cross-sectional measurement results data in a standardized format.The experimental results show that this method is not easily affected by environmental factors,has high measurement accuracy,and provides accurate data support for the design and construction of road maintenance projects,ensuring that road design meets traffic safety requirements.
