The invention relates to the technical field of intelligent traffic, in particular to a vehicle-mounted V2X collision early warning method based on road perception information fusion, which comprises a road perception system formed by interactively connecting a camera, a millimeter wave radar, an RSU (road side unit), an edge server and a switch; the radar is mainly used for detecting a target, and the camera transmits image data back to the edge server in real time. The HV of the vehicle is provided with vehicle-mounted V2X equipment, and the position, the direction angle and the speed of the vehicle are obtained from a positioning module of the equipment; after the vehicle HV obtains data of a crossing target object TA, target classification is firstly started; target classification is executed, a collision early warning result of the collision analysis thread is added into a danger arbitration queue, and early warning information with the highest grade is prompted to an HV driver of the vehicle in a voice and image mode; travelers, carriers and road infrastructures are organically combined by fusing the V2X technology to form a pedestrian-vehicle-road integrated traffic cooperation system, and traffic accidents are reduced.

    本发明涉及智能交通技术领域,具体涉及基于道路感知信息融合的车载V2X碰撞预警方法,包括道路感知系统是由摄像机、毫米波雷达、RSU路侧单元、边缘服务器和交换机交互连接组成;雷达主要用于探测目标,摄像机实时将图像数据回传到边缘服务器;本车HV安装有车载V2X设备,从设备的定位模块获得本车的位置、方向角、速度;本车HV得到路口目标物TA的数据后,首先启动目标分类;执行目标分类、碰撞分析线程碰撞预警的结果加入危险仲裁队列,将等级最高的预警信息通过语音和图像的方式给本车HV司机进行提示;通过融合V2X技术将出行者、运载工具和道路基础设施有机结合起来,形成人车路一体化的交通协同系统,减少交通事故发生。
