The invention relates to the technical field of intelligent traffic, and discloses an intelligent traffic early warning method and an intelligent traffic early warning system, and the method comprises the steps: obtaining a first object target and a second object target approaching the first object target through a road image, and obtaining the moving directions and moving speeds of the first object target and the second object target respectively; calculating the time required for shortening the distance between the first object target and the second object target to a first preset threshold value according to the moving directions and the moving speeds of the first object target and the second object target; when the time required for shortening the distance between the first object target and the second object target to reach a first preset threshold value is smaller than or equal to a second preset threshold value, predicting that traffic danger exists, and controlling an early warning response device to make a corresponding early warning response; and otherwise, continuing to carry out the traffic information acquisition step. According to the method, traffic dangerous event prediction can be carried out in real time, and the early warning response equipment can be controlled to give a warning prompt.
本发明涉及智能交通技术领域,公开了一种智能交通预警方法及智能交通预警系统,该方法通过道路图像获取第一对象目标与正在向第一对象目标靠近的第二对象目标,并分别获取第一对象目标和第二对象目标的移动方向和移动速度,通过第一对象目标、第二对象目标的移动方向和移动速度计算出第一对象目标与第二对象目标之间的距离缩短至第一预设阈值所需的时间;当第一对象目标与第二对象目标之间的距离缩短至达到第一预设阈值所需的时间小于或等于第二预设阈值时,则预测存在交通危险,控制预警响应设备作出相应的预警响应;否则,继续进行交通信息获取步骤;通过上述方法能够实时进行交通危险事件预测并能够控制预警响应设备作出警示提醒。
