| 摘 要： | 为了解决路面手工三维建模速度慢、工作量大等问题，本文面向规范化处理的高精度矢量数据，对不同路口进行精细化设计，自动生成路面三维模型。首先使用道路高精度三维信息采集软件，在获取的点云数据中半自动化提取准确的道路边线、道路标识线等矢量信息；然后针对不同路口进行精细化线形设计，提出连续四边形重建方法、弯道平滑处理方法、交叉口重建方法及路面标识线投射重建方法；最后对提取的高精度矢量数据进行规范化处理，在满足路面线形设计要求后，借助MAXScript脚本实现路面三维自动化建模。以车载移动测量系统获取的某段道路点云数据进行试验，验证了该方法的可行性和有效性。

| Abstract: | In order to solve the problems of slow road manual 3D modeling and heavy workload, this paper focuses on standardized processing of high-precision vector data, carries out refined design for different intersections, and automatically generates road 3D models. First, this paper uses road high-precision three-dimensional information acquisition software to semi-automatically extract accurate road edges, road markings and other vector information from the acquired point cloud data. Then, it carries out refined linear design for different intersections, and proposes continuous quadrilateral reconstruction methods and curves smoothing processing method, intersection reconstruction method and road marking reconstruction method. Finally, the extracted high-precision vector data is standardized. After meeting the road alignment design requirements, MAXScript is used to realize the road 3D automatic modeling. Taking the point cloud data of a certain section of the road obtained by the vehicle-mounted mobile measurement system as an example, the experiment verifies the feasibility and effectiveness of the method. |
