Background:

Multi-Object Tracking (MOT) is crucial for autonomous driving, generating object trajectories and predicting future motion.
The track-by-detection paradigm dominates 3D MOT, relying on object detection and data association.
Current 3D MOT data association predominantly uses bipartite matching solved by the Hungarian algorithm.

Purpose of the Study:

To adapt a successful two-stage data association method from 2D to 3D Multi-Object Tracking.
To provide a competitive alternative to the standard one-stage bipartite matching approach in 3D MOT.

Main Methods:

Adapted a two-stage data association algorithm for 3D environments.
Evaluated the method on benchmark datasets (NuScenes and Waymo).
Compared performance against a baseline using one-stage bipartite matching.

Main Results:

Achieved 0.587 Average Multi-Object Tracking Accuracy (AMOTA) on the NuScenes validation set.
Attained 0.365 AMOTA (at level 2) on the Waymo test set.
Demonstrated superior performance compared to the one-stage bipartite matching baseline.

Conclusions:

The proposed two-stage data association method offers a significant improvement for 3D MOT.
This advancement contributes to more robust perception systems for autonomous vehicles.
The findings suggest a promising direction for future research in 3D object tracking.
