News

  • 2023/08: Our another work named VI-Net is accepted by ICCV2023.
  • 2023/07: Codes tested with Pytorch 1.9.0 and CUDA 11.2 are also provided.

Requirements

The code has been tested with

  • python 3.6.5
  • pytorch 1.3.0
  • CUDA 10.2

Some dependent packages：

pip install gorilla-core==0.2.5.6

cd model/pointnet2
python setup.py install

Data Processing

Download the data provided by NOCS (camera_train, camera_test, camera_composed_depths, real_train, real_test, ground truths, and mesh models) and segmentation results (Link), and unzip them in data folder as follows:

data
├── CAMERA
│   ├── train
│   └── val
├── camera_full_depths
│   ├── train
│   └── val
├── Real
│   ├── train
│   └── test
├── gts
│   ├── val
│   └── real_test
├── obj_models
│   ├── train
│   ├── val
│   ├── real_train
│   └── real_test
├── segmentation_results
│   ├── train_trainedwoMask
│   ├── test_trainedwoMask
│   └── test_trainedwithMask
└── mean_shapes.npy

Run the following scripts to prepare the dataset:

python data_processing.py

Training DPDN under Different Settings

Train DPDN under unsupervised setting:

python train.py --gpus 0,1 --config config/unsupervised.yaml

Train DPDN under supervised setting:

python train.py --gpus 0,1 --config config/supervised.yaml

Evaluation

Download trained models and test results [Link]. Evaluate our models under different settings:

python test.py --config config/unsupervised.yaml
python test.py --config config/supervised.yaml

or directly evaluate our results on REAL275 test set:

python test.py --config config/unsupervised.yaml --only_eval
python test.py --config config/supervised.yaml --only_eval

One can also evaluate our models under the easier unsupervised setting with mask labels for segmentation (still without pose annotations):

python test.py --config config/unsupervised.yaml --mask_label

or

python test.py --config config/unsupervised.yaml --mask_label --only_eval

Results

Qualitative results on REAL275 test set:

IoU25 IoU75 5 degree 2 cm 5 degree 5 cm 10 degree 2 cm 10 degree 5 cm
unsupervised 72.6 63.8 37.8 45.5 59.8 71.3
unsupervised (with masks) 83.0 70.3 39.4 45.0 59.8 72.1
supervised 83.4 76.0 46.0 50.7 70.4 78.4
