Installation 👨‍🔧

We recommend creating a new Anaconda environment to use pizza. Use the following commands to setup a new environment:

conda env create -f environment.yml
conda activate pizza
pip install mmcv-full==1.3.8 -f https://download.openmmlab.com/mmcv/dist/cu102/1.7.0/index.html
# Assuming that you are in the root folder of "pizza"
cd mmsegmentation
pip install -e .  # or "python setup.py develop"

# Optional: If you don't have initial boxes
cd mmdetection
pip install -r requirements/build.txt
pip install -v -e .

2D object tracking in the wild with 1st Place Solution for the UVO Challenge

Note: We track objects not seen during the training with 1st Place Solution for the UVO Challenge. This implementation is slightly modified comparing to the original repo to make it easy to run on different dataset of BOP challenge:

1. Download pretrained-weights:

• Pretrained weight of segmentation model (2.81GB)
• Pretrained weight of RAFT things (21MB)
• (Optinal) Pretrained weight of detection model (2.54GB) (when initial boxes are not provided)

export WEIGHT_ROOT=$YOUR_WEIGHT_ROOT
# for example export WEIGHT_ROOT=/home/nguyen/Documents/results/UVO
bash ./scripts/download_uvo_weights.sh

Optional: You can download with attached gdrive links above manually.

2. Organize the dataset as in BOP challenge, for example with YCB-V dataset:

$INPUT_DATA (ycb-v folder)
    ├── video1 
        ├── rgb
        ├── ...
    ├── video2 
        ├── rgb
        ├── ...
    ├── ...

3. Run detection and segmentation

Update file "input_dir", "output_dir" and "weight_dir" in configs/config_path.json

python -m lib.track.demo

3D pose regression

1. Download testing datasets. We provide here the pre-generated synthetic images for ModelNet's experiments (checkout DeepIM paper for more details):

• Synthetic images from ModelNet's CAD models (2.38 GB)

bash ./scripts/download_modelNet.sh

2. To launch a training:

python -m train --exp_name modelNet

3. To reproduce the quantitative results:

• Download checkpoint

bash ./scripts/download_modelNet_checkpoint.sh

python -m test --exp_name modelNet --checkpoint $CHECKPOINT_PATH
