The invention discloses a road congestion detection method, medium, device and system, and the method comprises the steps: taking continuously obtained video frames as the input of a vehicle detection model, so as to detect the driving speed of each vehicle in the video frames; in response to the fact that the proportion of the low-speed vehicles is larger than a first threshold value and the number of the low-speed vehicles is larger than a second threshold value, the vehicle detection model detects the congested vehicles in the video frame so as to mark the congested vehicles; wherein the running speed of the low-speed vehicle is lower than a preset speed threshold value; re-checking the feature consistency of the congested vehicles by adopting a multi-modal large model, and generating alarm information of the congested vehicles passing the re-checking; wherein the model parameters of the multi-modal large model are greater than the model parameters of the vehicle detection model. Through the above mode, the training cost of the small model can be reduced, the road congestion detection speed of the model is improved, and the road congestion detection accuracy is improved.

    本申请公开了一种道路拥堵检测方法、介质、设备及系统,包括:将持续获取的视频帧作为车辆检测模型的输入,以检测视频帧中各车辆的行驶速度;响应于低速车辆的占比大于第一阈值,且低速车辆的数量大于第二阈值,则车辆检测模型对视频帧中的拥堵车辆进行检测,以标记出拥堵车辆;其中,低速车辆的行驶速度低于预设速度阈值;采用多模态大模型复核拥堵车辆的特征一致性,并生成通过复核的拥堵车辆的告警信息;其中多模态大模型的模型参数大于车辆检测模型的模型参数。通过上述方式,本申请能够降低小模型的训练成本,提高模型对道路拥堵的检测速度,提高道路拥堵的检测准确性。
