The invention relates to an urban-level digital twin traffic system, and the system comprises a data planning and pushing unit which is configured to obtain data of third-party road test monitoring equipment, and the data comprise road data and vehicle data in a real space; the vehicle model module is configured to make model data of the vehicle in the virtual three-dimensional scene; the model scene space coordinate matching module is configured to obtain the data of the data planning and pushing unit and the vehicle model module, perform spatial position calibration on the road model, and enable the road data in the real space to be matched with the coordinates of the road model; and the data fusion module is configured to divide the road into a plurality of sub-road sections, acquire data of the third-party road test monitoring equipment in each sub-road section, perform interpolation calculation on the acquired data, display the data in an animation form, execute the animation and realize display of virtual and real mapping of the traffic vehicle. According to the invention, the problems of inaccurate space coordinates of virtual and real scenes, inconsistent model and actual vehicle information and the like in the prior art are solved.

    本发明涉及一种城市级数字孪生交通系统,包括:数据规划及推送单元,配置为获取第三方路测监控设备的数据,所述数据包括真实空间中的道路数据和车辆数据;车辆模型模块,配置为在虚拟三维场景中制作车辆的模型数据;模型场景空间坐标匹配模块,配置为获取所述数据规划及推送单元及车辆模型模块的数据,将道路模型进行空间位置校准,使真实空间中的道路数据与道路模型坐标匹配;数据融合模块,配置为将道路划分多个子路段,获取各子路段中第三方路测监控设备的数据,对获取的数据进行插值计算,以动画的形式进行展示,执行动画,实现交通车辆虚实映射的展示。本发明解决了现有技术中虚实场景空间坐标不准,模型和实际车辆信息不一致等问题。
