The invention discloses an unmanned aerial vehicle aerial photography-based expressway traffic monitoring system, which comprises a camera arranged on a cradle head, the cradle head is located on an unmanned aerial vehicle, the unmanned aerial vehicle flies at a low speed above a specified expressway lane, and the unmanned aerial vehicle runs opposite to a vehicle on the expressway lane; the camera shoots a pavement image of a specified high-speed lane based on the unmanned aerial vehicle and sends the pavement image to the image recognition unit; the image recognition unit recognizes a vehicle in the road surface image; the road surface monitoring unit determines whether a traffic jam has occurred in the designated expressway lane based on the position of the vehicle in the adjacent frame. According to the invention, by improving the YOLOv5 network structure, the recognition precision of the vehicle target in the pavement image is improved, and the recognition precision of the traffic condition of the expressway pavement is improved.

    本发明公开一种基于无人机航拍的高速道路交通监测系统,包括:设于云台上的摄像机,云台位于无人机上,无人机在指定高速车道的上空低速飞行,无人机与该高速车道上的车辆相向行驶;摄像机,基于无人机拍摄指定高速车道的路面图像,并发送至图像识别单元;图像识别单元识别出路面图像中的车辆;路面监测单元基于相邻帧中车辆的位置来判定指定高速车道是否发生交通堵塞。本发明通过对YOLOv5网络结构进行改进,提高路面图像中的车辆目标识别精度,提高高速路面的交通状况的识别精度。
