Research on 3D Digitization Technology and Application of Highway Infrastructure

摘要: 开展三维数字化研究是推动公路高质量发展的基础，文章结合公路行业实际业务需求，对比分析BIM建模、车载激光雷达扫描、无人机倾斜摄影等三种公路基础设施三维数字化技术的特点及其适用范围，设计三维数字化应用系统总体框架，开发数据服务、三维可视化、资产管理、统计分析、智能巡查、路面病害管理等功能模块，支撑公路行业数字化转型。

Abstract: The study of 3D digitization is the foundation of promoting the high-quality development of highway. Based on the actual business needs of the highway industry, this paper compared the characteristics and application scope of three 3D digitization technologies for highway infrastructure, such as BIM modeling, vehicle-mounted Lidar scanning, and UAV tilt photography. Then, the overall framework of 3D digitization application system was proposed. Finally, the functional modules of the system including data services, 3D visualization, asset management, statistical analysis, intelligent inspection and pavement disease management were developed. This study could support the digital transformation of the highway industry.
