The invention discloses a method for realizing vehicle-road collaborative data communication based on regional grouping, which relates to the technical field of traffic communication, and comprises the following steps: providing core management services of manual grouping and intelligent algorithm grouping, and actively and automatically updating; regional grouping division is carried out from two dimensions of intersections and roads; performing intra-group and inter-group data processing including pre-fusion of intra-group point cloud image original data and post-fusion of semantic data; the data after data processing is finally broadcasted in a data broadcasting mode, a data receiving end calculates which group of group data is used for vehicle-road cooperation according to the position information of a vehicle, actively subscribes to the corresponding group data in combination with a packet routing table, and carries out inter-group fusion and alignment operation and advanced safe switching in a plurality of group overlapping areas at the same time. A data communication mode can be applied to the field of vehicle-road cooperative automatic driving in a low-cost, fast, efficient and high-quality manner.

    本发明公开了一种基于区域分组实现车路协同数据通信的方法,涉及交通通信技术领域,包括:提供人工分组以及智能算法分组的核心管理服务,主动和自动更新;从交叉口和道路两个维度进行区域分组划分;进行组内组间的数据处理,包括组内点云图像原始数据的前融合、语义化数据的后融合;数据处理后的数据最终通过数据广播方式广播出去,数据接收端根据自车的位置信息计算使用哪组group数据用来车路协同,结合分组路由表主动订阅相应group数据,同时在多个group重叠区域做组间融合和对齐操作以及提前安全切换。能够将数据通信模式低成本、快捷高效以及高质量的应用于车路协同的自动驾驶领域。
