The invention provides an expressway traffic jam event recognition method and device, electronic equipment and a storage medium, in the method, a camera carried by an unmanned aerial vehicle is adopted to collect real-time traffic video streams of an expressway, a wider road view can be shot at high altitude, more comprehensive traffic condition information can be obtained, and the traffic jam event recognition efficiency is improved. The method can more accurately sense the traffic jam condition of the whole highway, provides a better data basis for subsequent analysis and early warning, saves the cost, calculates the average vehicle body length and the Euclidean distance between any two vehicles through the vehicle information obtained through detection, and improves the traffic jam detection accuracy. Whether the two vehicles are in traffic jam is directly judged according to the relation between the average vehicle body length and each Euclidean distance, and then whether the traffic jam exists in the video frame image is determined, which is closer to the physical characteristics of the actual traffic jam, so that the actual traffic jam event can be detected more accurately and timely, and the traffic jam detection efficiency is improved. And the occurrence of false alarm and missing alarm is reduced, and the response speed is higher.

    本发明提供了一种高速公路堵车事件的识别方法、装置、电子设备和存储介质,该方法中,采用无人机搭载的相机采集高速公路的实时交通视频流,可以在高空拍摄到更广阔的道路视野,可以获取更全面的交通状况信息,能够更准确地感知高速公路整体的堵车情况,为后续分析和预警提供更好的数据基础,节省了成本,另外,通过检测得到的车辆的信息计算平均车身长度和任意两辆车辆之间的欧式距离,进而根据平均车身长度和各欧式距离之间的关系直接地判断两辆车辆之间是否存在堵车情况,进而确定视频帧图像中是否存在堵车,更贴近实际堵车发生的物理特征,从而能够更精准地、及时地检测出实际的堵车事件,减少了误报和漏报的情况发生,响应速度更快。
