JRMOT: A Real-Time 3D Multi-Object Tracker
and a New Large-Scale Dataset

JRMOT is a 3D multi object tracking system that:

Is real-time
Is online
Fuses 2D and 3D information
Achieves State of the Art performance on KITTI

We also release JRDB:

A dataset with over 2 million annotated boxes and 3500 time consistent trajectories in 2D and 3D
Captured in social, human-centric settings
Captured by our social mobile-manipulator JackRabbot
Contains 360 degree cylindrical images, stereo camera images, 3D pointclouds and more sensing modalties

Tracking System

Our system is built on top of state of the art 2D and 3D detectors (mask-RCNN and F-PointNet respectively). These detections are associated with predicted track locations at every time step.
Association is done via a novel feature fusion, as well as a cost selection procedure, followed by Kalman state gating and JPDA.
Given the JPDA output, we use both 2D and 3D detections in a novel multi-modal Kalman filter to update the track locations.

Benchmark Evaluation

We evaluate our system on the 2D tracking benchmark (KITTI) to compare to other trackers, and on JRDB, to set up a competitive baseline. We achieve State of the Art tracking MOTA of 85.7% on the KITTI car tracking benchmark, and 46.33% on the KITTI pedestrian benchmark. Further, we achieve 20.2% MOTA running at 25 fps on the JRDB dataset.

On-Robot Evaluation

We evaluate our tracker on JackRabbot on 110 seconds of data, captured on our university campus. We test in situations as close to real world as possible, with 1-7 people per scene, 14 unique identitites across all sequences, and in indoor and outdoor settings. We record only 4 ID switches and 1 lost track across all tested sequences, at an average of 9.5 fps.

Code and Paper

We release our ROS implementation of our tracker, written in Python. Code can be found here . More details can be found here .
