Recently, the Xlab team of GAC R&D Center ranked first in the world on the pure vision list in the dynamic multi-object tracking (MOT) category of the internationally authoritative nuScenes autonomous driving test competition. Due to its self-developed XTracker method, which has significantly enhanced the key indicator, AMOTA (average multi-object tracking accuracy), from the previous 39.8% to 43.0%. This technological breakthrough not only provides strong support for GAC Group's autonomous driving but also promotes the practical application of the technology in autonomous driving scenarios.
