摘　　要：道路部件级实景三维(3D)是实景3D中国建设的重要内容,传统测绘手段作业强度大、作业效率低,难以满足城市空间信息快速获取的需求。车载移动测量系统集激光扫描技术、高精度定位定姿技术、影像获取技术于一身,可高效获取道路3D空间数据,生产部件级实景3D成果,优势明显。本研究使用SSW车载激光建模测量系统获取首都核心区15km道路高精度3D空间数据,基于激光点云、全景影像以及同步高清侧面影像数据,使用人工智能全自动提取道路地物要素的3D矢量信息。依据道路部件不同地物的特征采用不同的建模方式,形成道路结构化建模方案,开展高精细道路部件级建模试验,并对成果进行精度验证。结果表明SSW数据成果完全满足国家新型基础测绘北京试点的技术要求。Road component-level three-dimensional(3D)real scene(3DRS)is an important part of the construction of 3DRS in China.Conventional surveying and mapping methods feature high operational intensity and low efficiency,making it challenging to meet the demand for rapid access to urban spatial information.By integrating laser scanning technology,high-precision positioning and orientation technology,as well as image acquisition technology,the vehicle-mounted mobile surveying system efficiently captures 3D spatial data of roads and produces component-level 3DRS results,which offers significant advantages.This paper utilized the SSW vehicle-mounted laser modeling and measurement system to obtain highly precise 3D spatial data for a total road length of 15 km in Beijing's core area.Based on data from laser point cloud,panoramic images and synchronous high-definition side images,artificial intelligence was employed to automatically extract the 3D vector information pertaining to ground objects on roads.Based on characteristics exhibited by different ground objects within road components,different modeling techniques were applied to establish a comprehensive road structural modeling scheme.Subsequently,the high-precision road component level modeling experiments were conducted,and the accuracy of the results was verified.The results show that the SSW data could meet the technical requirements of the national new surveying and mapping pilot project in Beijing.
