AB3DMOT
A real-time baseline 3D multi-object tracking system using LiDAR point clouds, combining 3D Kalman filter and Hungarian algorithm.
What is AB3DMOT?
AB3DMOT is a baseline system for 3D multi-object tracking that uses LiDAR point clouds to track objects in real-time for applications like autonomous driving. It combines a 3D Kalman filter with the Hungarian algorithm for state estimation and data association, achieving high accuracy and speed. The project also introduces new evaluation metrics to better assess 3D MOT performance.
Researchers and engineers working on autonomous vehicles, robotics, or computer vision who need efficient and accurate 3D object tracking solutions. It's particularly useful for those benchmarking or developing real-time perception systems.
Developers choose AB3DMOT because it provides a simple, high-performance baseline that is both state-of-the-art in accuracy and extremely fast, running at 214.7 FPS. Its modular design and support for major datasets like KITTI and nuScenes make it a practical and reliable choice for 3D MOT tasks.

Pros & Cons
Pros
Runs at 214.7 FPS, as highlighted in the README, making it suitable for real-time autonomous driving and robotics applications.
Achieves a 3D MOTA of 76.47 on KITTI, establishing a high-performance baseline for 3D multi-object tracking benchmarks.
Designed to work with off-the-shelf 3D object detectors, allowing flexibility in choosing detection models like PointRCNN for LiDAR point clouds.
Introduces new metrics such as sAMOTA for extended 3D MOT evaluation on KITTI, improving assessment accuracy beyond traditional methods.
Offers a real-time version for Robot Operating System, facilitating deployment in robotics environments with minimal additional development.
Cons
Requires integration with external 3D detectors, adding complexity and potential compatibility issues if detectors are not pre-configured.
Primarily supports KITTI and nuScenes datasets; adapting to other formats or sensors may require significant code modifications and effort.
Installation instructions warn of potential errors, indicating a non-trivial setup process that can be time-consuming for new users.
Relies on standard Kalman filter and Hungarian algorithm, which may not leverage recent advances in deep learning for handling complex scenarios like severe occlusions.
