Preparing Data

Download following data before using the code in this repository:

Annotations and 2D pose predictions for the Campus and the Shelf datasets can be downloaded here. Credit to VoxelPose.
Follow the instructions on the CMU Panoptic Github repo to download the annotations. 2D pose predictions can be downloaded here.
Pre-trained models can be downloaded here.

The data should be organized as follows:

    ROOTDIR/
        └── data/
            └── Campus/
                └── actorsGT.mat
                └── calibration_campus.json
                └── pred_campus_maskrcnn_hrnet_coco.pkl
            └── Shelf/
                └── actorsGT.mat
                └── calibration_shelf.json
                └── pred_shelf_maskrcnn_hrnet_coco.pkl

Training and Inference

Below are the commands for training our model on different datasets.

The Campus dataset:

    python run/train.py --cfg configs/campus/config.yaml

The Shelf dataset:

    python run/train.py --cfg configs/shelf/config.yaml

The CMU Panoptic dataset:

    python run/train.py --cfg configs/panoptic/config.yaml

Below are the commands for performing inference with our pre-trained models.

The Campus dataset:

    python run/validate.py --cfg configs/campus/config.yaml -t pretrained

The Shelf dataset:

    python run/validate.py --cfg configs/shelf/config.yaml -t pretrained

The CMU Panoptic dataset:

    python run/validate.py --cfg configs/panoptic/config.yaml -t pretrained
