Abstract:

Multi-target tracking algorithms based on camera sensors are crucial to autonomous driving. In driving scenarios, traditional association schemes based on Intersection over Union(IoU) of front and back frames are subject to a great deal of ID switches, which is more pronounced in the case of opposing traffic and self-turning vehicles. In this paper, the target's motion speed in the 2D plane is taken as a variable to extend the matching space to design IoU based on the target's speed change: the Velocity IoU, so as to optimize the front and back frame target association method. Meanwhile, a self-supervised appearance model is used to extract the appearance features of different targets. Based on the above motion model as well as the appearance model, a complementary association strategy is proposed, which ultimately achieves multi-category multi-target tracking in driving scenarios. The method is validated on BDD100K, with corresponding mMOTA of 45.2, mIDF1 of 55.2, and IDs of 8 793, which outperforms most tracking algorithms.

Key words: autonomous driving, multi-target tracking, multi-category
