Self-Supervised Mesh Reconstruction (SMR)

This is the source code of Self-Supervised 3D Mesh Reconstruction From Single Images (CVPR-2021).

Requirements

• Linux
• Python >= 3.6
• CUDA >= 10.0.130 (with nvcc installed)

Installation

Create Environment

$ conda create --name smr python=3.7
$ conda activate smr

Install from requirements.txt

You can directly install the requirements through:

$ pip install -r requirements.txt

Install packages Seperately

You can also install the required packages seperately

• Pytorch (Please first check your cuda version)

  $ conda install pytorch==1.6.0 torchvision==0.7.0 cudatoolkit=10.2 -c pytorch
  

• Kaolin Library

  $ git clone --recursive https://github.com/NVIDIAGameWorks/kaolin
  $ git checkout v0.9.1
  $ python setup.py develop
  

• Others: tqdm, trimesh, imageio, tensorboard.

Training and Testing

Training and Testing On the CUB-200-2011 (Bird) dataset

• Dataset

  Download the processed data from Google Drive.

• Run

  DATA_ROOT=/path/to/Bird/
  $ python train.py --imageSize 128 \
                      --batchSize 24 \
                      --lr 0.0001 \
                      --niter 500 \
                      --dataroot $DATA_ROOT \
                      --template_path ./template/sphere.obj \
