Running time:4e-4 s
Environment:>8 cores @ 3.0 Ghz (Python)

Method Description:
Traditional 3D MOT approaches face critical
challenges: geometric similarity metrics (e.g., IoU-
based) degrade at long ranges with high
computational costs, while distance-based methods
fail to capture object orientation and shape; the
effects of occlusion and the intricate relative ego-
object motion degrade tracking performance in
dynamic scenes. To this end, we propose PB-MOT, an
online framework integrating two key innovations:
ego-motion-compensated state estimation that
decouples dynamic interactions; and a rotated
ellipse association algorithm unifying pose and
shape-aware matching with adaptive distance
constraints. Evaluations on the KITTI benchmark show
that our PB-MOT achieves state-of-the-art
performance with a HOTA score of 81.94%, while
running at an impressive 2,402.76 FPS on CPU. This
enables real-time, high-fidelity perception and
tracking for resource-constrained robotic systems.

Detailed Results

From all 29 test sequences, our benchmark computes the HOTA tracking metrics (HOTA, DetA, AssA, DetRe, DetPr, AssRe, AssPr, LocA) [1] as well as the CLEARMOT, MT/PT/ML, identity switches, and fragmentation [2,3] metrics. The tables below show all of these metrics.
