Abstract:

In order to balance the tracking performance (i.e. the indicators of MOTA, MOTP and IDSW etc.) and tracking speed, especially, to solve the complexity of the post processing for video multi-target tracking, a multi-target tracking method based on autoregressive query mechanism is proposed, with training and verification conducted. The results of verification show that the inference of each frame of picture takes about 44 ms, and the accuracy of multi-target tracking reaches 58.9%. The model is integrated into the ROS platform of intelligent vehicle for testing and the results of test indicate that the algorithm proposed can achieve multi-target real-time tracking in complex traffic scenes, and the algorithm has good practical application value.

Key words: onboard multi-object tracking, deep learning, self-query tracking
