The invention relates to the technical field of traffic safety, in particular to a zebra crossing early warning method and system based on fusion perception, and the method comprises the steps: obtaining laser radar point cloud data and pedestrian signal lamp red and green state information of a zebra crossing region; performing target identification on the laser radar point cloud data by adopting a fusion sensing algorithm to obtain zebra crossing pedestrian information; the pedestrian information comprises the number of pedestrians and positions of the pedestrians; and performing early warning control on zebra crossing lamps in the zebra crossing area according to the zebra crossing pedestrian information and the pedestrian signal lamp red and green state information. Through the zebra crossing pedestrian information and the pedestrian signal lamp red and green state information, the zebra crossing lamp in the zebra crossing area is subjected to early warning control, so that the position of the pedestrian in the zebra crossing area is accurately identified through the zebra crossing lamp, and when a vehicle is out of control, a driver can observe the position of the pedestrian on the zebra crossing at a farther place so as to avoid the pedestrian; and the risk of pedestrians on the zebra crossing under the out-of-control vehicle condition is reduced.
本发明涉及交通安全技术领域,具体涉及一种基于融合感知的斑马线预警方法及系统,包括:获取斑马线区域的激光雷达点云数据和人行信号灯红绿状态信息;采用融合感知算法对所述激光雷达点云数据进行目标识别,获得斑马线行人信息;所述行人信息包括行人数量和行人位置;根据斑马线行人信息和人行信号灯红绿状态信息,对斑马线区域的斑马线灯进行预警控制。通过斑马线行人信息和人行信号灯红绿状态信息,对斑马线区域的斑马线灯进行预警控制,从而通过斑马线灯准确标识斑马线区域行人的位置,在车辆失控时,司机可以在较远的地方观测到斑马线上行人位置,从而避让行人,降低车辆失控情况下斑马线上行人的风险。
