The invention relates to a pedestrian safety early warning method applied to traffic, and the method comprises the steps: carrying out the track prediction and tracking of a detection target through a Kalman filter, so as to obtain the position, speed and acceleration information of each detection target, and dynamically calculating a pedestrian and vehicle interaction risk factor according to historical data; dynamically drawing a zebra crossing high-risk monitoring area according to the position, the speed, the acceleration, the risk factor and the road layout of each detection target; and when the detection target enters the zebra crossing high-risk monitoring area and the pedestrian and vehicle interaction risk factor is greater than a preset threshold value, starting image capture, and adjusting the state and the duration of the traffic signal lamp. According to the invention, the interaction risk factor between the pedestrian and the vehicle can be calculated, so that early warning and intervention can be carried out before potential dangers occur.

    本申请涉及一种应用于交通的行人安全预警方法,该方法包括利用卡尔曼滤波器对所述检测目标进行轨迹预测与追踪,以获取每个检测目标的位置、速度和加速度信息,并根据历史数据动态计算行人与车辆交互风险因子;根据每个检测目标的位置、速度、加速度、风险因子以及道路布局,动态绘制斑马线高风险监测区域;当检测目标进入斑马线高风险监测区域,且行人与车辆交互风险因子>预设阈值,则启动图像抓拍,并调整交通信号灯的状态及时长。本发明可以计算行人与车辆之间的交互风险因子,使得能够在潜在危险发生前进行预警和干预。
