This is the official repo for the implementation of Geo-Neus: Geometry-Consistent Neural Implicit Surfaces Learning for Multi-view Reconstruction, Qiancheng Fu*, Qingshan Xu*, Yew-Soon Ong, Wenbing Tao (* Equal Contribution), NeurIPS 2022.
We will release our pretrained models soon!

Setup

Installation

This code is built with pytorch 1.11.0 and pytorch3d 0.6.2. In addition, other packages listed in requirements.txt are required.
You can create an anaconda environment called geoneus with the required dependencies by running:

conda create -n geoneus python=3.7  
conda activate geoneus  
conda install pytorch==1.11.0 torchvision==0.12.0 cudatoolkit=11.3 -c pytorch  
conda install fvcore iopath  
conda install -c bottler nvidiacub  
conda install pytorch3d -c pytorch3d  
pip install -r requirements.txt

Data

Download the DTU data from Google Drive, which provides the files on sparse points and image pairs.

Running

Training

python exp_runner.py --mode train --conf ./confs/womask.conf --case <case_name>

Extract surface from trained model

python exp_runner.py --mode validate_mesh --conf ./confs/womask.conf --case <case_name> --is_continue

Evaluation

python eval.py --conf ./confs/womask.conf --case <case_name>
