The invention relates to the technical field of intelligent transportation, and discloses a collision early warning method, system and device. The method comprises the steps of obtaining a high-precision map and performing fragmentation processing on the high-precision map to obtain a preset map database; determining a first range according to the real-time position of the target vehicle, and obtaining a plurality of first map fragments in the first range based on a preset map database; in a preset geographic feature library, obtaining geographic feature tags corresponding to the first map fragments; determining a collision early warning range based on the geographic feature tags corresponding to all the first map fragments; acquiring a plurality of corresponding target traffic element data in the collision early warning range, and determining a collision state of the target vehicle based on all the target traffic element data; and based on the collision state, collision warning information is sent to the target vehicle. According to the scheme of the invention, the problems of low efficiency and poor real-time performance in collision early warning are solved, the access and calculation efficiency of traffic data is optimized, real-time collision early warning is realized, and the occurrence rate of traffic accidents is reduced.

    本发明涉及智能交通技术领域,公开了一种碰撞预警方法、系统及设备。方法包括:获取高精地图并对其进行分片处理,得到预设地图数据库;根据目标车辆的实时位置确定第一范围,基于预设地图数据库,获取位于第一范围内的若干第一地图分片;在预设地理特征库中,获取各第一地图分片对应的地理特征标签;基于所有第一地图分片对应的地理特征标签,确定碰撞预警范围;获取碰撞预警范围内对应的若干目标交通要素数据,基于所有目标交通要素数据,确定目标车辆的碰撞状态;基于碰撞状态,向目标车辆发送碰撞告警信息。本发明的方案解决了碰撞预警中效率低和实时性差的问题,优化了交通数据的访问和计算效率,实现实时碰撞预警,减少了交通事故发生率。
