MVS-Splatting: Fast Multi-View Stereo Depth Fusion for 3D Gaussian Splatting Initialization

This is the code repository for the paper with the same name. We also publish a dataset called Ghent29.

Repository structure

This repository contains 4 sub-repositories, each with their own README.md.

1. datasets: the instructions to download the datasets used in the paper.

2. gaussian-splatting: fork of 3DGS adapted for the paper.

3. MVSGaussian: fork of MVSGaussian (ECCV'24) adapter for the paper.

4. MVSSplatting: our code (depth estimation etc.)

How to use

Assuming you have a dataset with the SfM (and undistortion) step of COLMAP already applied:

dataset/
├── images/                # undistorted
└── sparse/                # PINHOLE
    └── 0/
        ├── cameras.bin
        ├── images.bin
        └── points3D.bin

Use MVSSplatting to generate sparse/0/points3D_mvs.bin. This contains the 3D Gaussian Splats to initialize the training process (see gaussian-splatting) with, instead of the COLMAP SfM point cloud. During/after training, you can use 3DGS' realtime viewers to visualize the splats.

MVSSplatting also has an optional GUI.
