The invention relates to the technical field of road early warning, and discloses a blind area pedestrian early warning method and system based on V2X and machine vision, and the key points of the technical scheme are that a road side end RSU carries out edge calculation, and starts to detect road pedestrian information; if the RSU at the roadside end detects that the pedestrian appears on the current road, tracking the pedestrian based on machine vision, and calculating the accurate position of the current pedestrian target; the road side end RSU broadcasts and sends blind area pedestrian information to external traffic participants, and when a driving vehicle enters a V2I communication range, a vehicle-mounted OBU receives pedestrian information of a front road; when the vehicle-mounted OBU receives the information of the pedestrian ahead, collision early warning calculation is carried out, and the possibility of collision is judged; the road pedestrian shielding detection problem can be solved in the roadside system, meanwhile, the vehicle-mounted equipment receives the pedestrian information from the blind area through V2I communication, the front road pedestrian information is obtained through the beyond-visual-range sensing capacity, the driving safety is improved, and the protection measures for the road pedestrians are perfected.
本发明涉及道路预警技术领域,公开了一种基于V2X与机器视觉的盲区行人预警方法与系统,其技术方案要点是路侧端RSU进行边缘计算,开始检测道路行人信息;若路侧端RSU检测到当前道路有行人出现,则基于机器视觉对行人进行跟踪,并计算出当前行人目标的准确位置;路侧端RSU将盲区行人信息广播发送给外界交通参与者,当行驶车辆进入V2I通信范围,则车载OBU接收前方道路的行人信息;车载OBU接收到前方行人信息时,进行碰撞预警计算,并判断发生碰撞的可能性;可以在路侧系统解决道路行人遮挡的检测问题,同时车载设备通过V2I通信接收来自盲区的行人信息,利用超视距的感知能力获取前方道路行人信息,提升了驾驶安全性,完善了对道路行人的保护措施。
