P2B: Point-to-Box Network for 3D Object Tracking in Point Clouds

Introduction

This repository is released for P2B in our CVPR 2020 paper (oral). Here we include our P2B model (PyTorch) and code for data preparation, training and testing on KITTI tracking dataset.

Preliminary

• Install python 3.6.

• Install dependencies.

    pip install -r requirements.txt

• Build _ext module.

    python setup.py build_ext --inplace

• Download the dataset from KITTI Tracking.

  Download velodyne, calib and label_02 in the dataset and place them under the same parent folder.

Evaluation

Train a new P2B model on KITTI data:

python train_tracking.py --data_dir=<kitti data path>

Test a new P2B model on KITTI data:

python test_tracking.py --data_dir=<kitti data path>

Please refer to the code for setting of other optional arguments, including data split, training and testing parameters, etc.
