[0058] The invention is further described below with reference to the accompanying drawings.
[0059] figure 1 A total algorithm flow chart is given. For the first frame of the video stream, the position of the vehicle on the image is locked using the vehicle detection algorithm, and each vehicle is assigned a filter for tracking. Considering that a new vehicle may appear in the video stream, vehicle detection, refresh filter number is performed and the filter group parameters are performed for each frame. Finally, the association of the data association policy guarantees the association of the interframe vehicle.
[0060] The convolutional neural network structure and parameters used in the vehicle detection portion in step A3 are shown in the following table:
[0061]
[0062] figure 2 The algorithm flow diagram of how to filter success match data pairs is given. The input data includes two parts, detection results, and tracking results. Where O 1 O 2 , ..., o n Indicates th...
