This repository provides code, data and pretrained models for FRI-Net.

[Paper]

• We have updated the model code.
• We have updated the evaluation and the training codes.

Since our code is built upon Roomformer, we follow the environment setup from Roomformer.

# Create conda environment
conda create -n frinet python=3.8
conda activate frinet

# install pytorch and other requried packages
pip install torch==1.9.0+cu111 torchvision==0.10.0+cu111 -f https://download.pytorch.org/whl/torch_stable.html
pip install -r requirements.txt

# Compile the defromable-attention models from deformable-DETR
cd models/ops
sh make.sh

We directly provide the processed data and pretrained checkpoints, please download them and organize them as following:

FRI-Net/
└── data/
    └── stru3d/
        ├── annotations/
        ├── input/
        ├── occ/
        ├── ...
└── checkpoints/
    ├── pretrained_ckpt.pth
    ├── pretrained_room_wise_encoder.pth

For details on data preprocessing, please refer to datasets.

Please run the following command to evaluate the model on Structured3D test set:

python eval_stru3d.py --checkpoint ./checkpoints/pretrained_ckpt.pth

You can get the visualized results on the results.

To train FRI-Net on Structured 3D, please run the following command:

python train_stru3d.py --phase=0 --job_name=train_stru3d
python train_stru3d.py --phase=1 --job_name=train_stru3d
python train_stru3d.py --phase=2 --job_name=train_stru3d
