Fast-MVSNet

PyTorch implementation of our CVPR 2020 paper:

Fast-MVSNet: Sparse-to-Dense Multi-View Stereo With Learned Propagation and Gauss-Newton Refinement

Zehao Yu, Shenghua Gao

How to use

git clone git@github.com:svip-lab/FastMVSNet.git

Installation

pip install -r requirements.txt

Training

• Download the preprocessed DTU training data from MVSNet and unzip it to data/dtu.

• Train the network

  python fastmvsnet/train.py --cfg configs/dtu.yaml

  You could change the batch size in the configuration file according to your own pc.

Testing

• Download the rectified images from DTU benchmark and unzip it to data/dtu/Eval.

• Test with the pretrained model

  python fastmvsnet/test.py --cfg configs/dtu.yaml TEST.WEIGHT outputs/pretrained.pth

Depth Fusion

We need to apply depth fusion tools/depthfusion.py to get the complete point cloud. Please refer to MVSNet for more details.

python tools/depthfusion.py -f dtu -n flow2
