摘　　要：随着“实景三维中国”建设目标的深入推进,部件级实景三维产品需求日益增长。本文从顶层设计出发,研究了以道路高精地图为典型代表的部件级实景三维产品全流程建设思路和快速构建方法,阐述了道路高精地图产品的实体化、语义化、三维化特征的关键技术,构建具有“一码多态”特征的道路部件级实景三维产品,并以成都高新南区5 km道路路段作为研究区,验证了该技术架构的可行性。研究结果表明,最终的道路高精地图部件产品精度、完整性、一致性等符合规范和设计要求,一定程度上提升了生产效率,也为其他城市部件级实景三维发展建设提供了参考依据。With the deepening of the construction goal of“Real 3D China”,the demand for component level real 3D products is increasing day by day.Starting from the top-level design,this study investigates the full process construction ideas and rapid construction methods of component level real 3D products,represented by high-precision road maps.It elaborates on the key technologies of the entity,semantics,and 3D features of high-precision road map products,constructs road component level realistic 3D products with“one code polymorphism”features,and verifies the feasibility of this technical architecture using a 5-kilometer road section in the South High tech Zone of Chengdu as the research area.The research results indicate that the final high-precision road map component products meet the specifications and design requirements in terms of accuracy,integrity,consistency,etc.,which to a certain extent improves production efficiency and provides a reference basis for the development and construction of component level real 3D in other cities.
