The invention discloses a full-automatic traffic fault warning method and system based on an unmanned aerial vehicle. The method comprises the steps that (1) the unmanned aerial vehicle provided with a fault warning board is started and hovers at the position F m behind a fault vehicle; (2) shooting a real-time image of a lane behind the unmanned aerial vehicle through a camera, and carrying out data processing on the image to obtain vehicle position information and lane position information; the speed of the vehicle on the lane where the fault vehicle is located is obtained in real time through a speed measuring radar installed on the unmanned aerial vehicle; (3) comparing the vehicle position information with the lane position information, identifying a vehicle closest to the fault warning board on the lane where the current fault vehicle is located, and calculating a speed recommendation value of the vehicle on the lane where the fault vehicle is located according to the speed corresponding to the vehicle; and (4) acquiring a speed recommendation value and transmitting the speed recommendation value to a fault warning board for display. According to the method, the warning board can be safely placed, the speed recommendation interval is provided for the rear coming vehicle, and the safety and efficiency of placing the warning board when the vehicle breaks down on the highway are improved.

    本发明公开了基于无人机的全自动交通故障警示方法与系统,包括:(1)启动安装有故障警示牌的无人机并于故障车辆后方F米的位置悬停;(2)通过摄像头拍摄无人机后方车道实时图像并对图像进行数据处理,获取车辆位置信息与车道位置信息;通过安装于无人机上测速雷达实时获得故障车辆所在车道上车辆的速度;(3)通过比较车辆位置信息与车道位置信息,识别当前故障车辆所在车道上距离故障警示牌最近的车辆,根据该车辆对应的速度计算得出故障车辆所在车道上车辆的速度推荐值;(4)获取速度推荐值传输至故障警示牌显示。本发明能够安全放置警示牌并为后方来车提供速度推荐区间,提高了车辆在高速公路发生故障时放置警示牌的安全性和效率性。
