Introduction

This repository is built for:

MVImgNet: A Large-scale Dataset of Multi-view Images (CVPR2023) [arXiv]

If you find our work useful in your research, please consider citing:

MVImgNet

MVImgNet contains 6.5 million frames from 219,188 videos crossing objects from 238 classes. We provide an OneDrive link to download the full data. Please fill out this form to get the download link and password.

We split the full data into 42 zip files, the total size is about 3.4 TB.

Usage

cd path/to/mvimgnet_zip_file
unzip './*.zip'

Folder structure

|-- ROOT
    |-- class_label
        |-- instance_id
            |-- images
            |-- sparse/0
                |-- cameras.bin   # COLMAP reconstructed cameras
                |-- images.bin    # binary data of input images
                |-- points3D.bin  # COLMAP reconstructed sparse point cloud (not dense)

The mapping between class_label and class name can be found in mvimgnet_category.txt.

The images folder contains the multi-view images, and the sparse folder contains the reconstructed camera parameters using COLMAP. It is recommended to use the functions provided by COLMAP to read the binary files under sparse folder. Moreover, the gen_poses function from this repo is recommended to convert the poses for NeRF training.
