The invention provides a vehicle active safety early warning method, system and device in a highway vehicle-person conflict scene and a medium, and the method comprises the following steps: continuously collecting pedestrian position information and vehicle position information, and predicting pedestrian crossing time; dividing pedestrian positions into a same-direction lane, an opposite-direction lane, a central isolation belt, a same-direction vehicle road side and an opposite-direction vehicle road side based on the continuously collected pedestrian position information, and judging whether the possibility of collision between vehicles and pedestrians exists based on the predicted pedestrian crossing time and the continuously collected vehicle position information; if the conflict possibility exists, sending or displaying the recommended driving speed to the conflict vehicle; according to the method for obtaining the pedestrian crossing information based on the prediction method, the motion state, which cannot be recognized by a general pedestrian detection method, of the pedestrian on the expressway can be effectively recognized, the pedestrian crossing time and pedestrian motion are monitored in real time, and the accuracy of active safety early warning of the vehicle is improved.

    本发明提供高速公路车‑人冲突场景车辆主动安全预警方法、系统、设备及介质,包括以下步骤:持续采集行人位置信息以及车辆的位置信息,并预测行人穿越时间;基于持续采集的行人位置信息将行人位置划分为同向车道、对向车道、中央隔离带、同向车道路侧以及对向车道路侧,基于预测行人穿越时间和持续采集的车辆位置信息判断是否存在车辆与行人冲突的可能;若存在冲突的可能,则向冲突车辆发送或展示推荐行驶速度;本申请基于预测的方法获取行人穿越信息的方法,能够有效识别一般行人检测方法无法识别的高速公路上行人的运动状态,实现对行人穿越时间和行人运动实时监测,提高车辆主动安全预警的准确性。
