What's inside BlendedMVS

Understand the BlendedMVS dataset structure

master

The BlendedMVS(G) dataset follows the MVSNet input format. After downloading, your DATA_ROOT should be organized as follows:

BlendedMVG_list.txt, BlendedMVS_list.txt, BlendedMVS+_list.txt, BlendedMVS++_list.txt: List files containing project IDs.
PIDx/ (where x is the unique project ID from the list files):
- blended_images/: Contains .jpg images and _masked.jpg versions.
- cams/: Contains pair.txt and camera parameters (*_cam.txt).
- rendered_depth_maps/: Contains .pfm depth maps.

Download the BlendedMVS+ dataset

master

The BlendedMVS+ dataset is provided as a series of split files. Use the following bash script to download all 42 split files (BlendedMVS1.z01 to BlendedMVS1.z42) and the final .zip descriptor from the GitHub release.

#!/bin/bash

# Base URL
BASE_URL="https://github.com/YoYo000/BlendedMVS/releases/download/v1.0.1"

# Download split files BlendedMVS1.z01 to BlendedMVS1.z42
for i in $(seq -w 1 42); do
    FILE="BlendedMVS1.z$i"
    echo "Downloading $FILE..."
    wget -c "${BASE_URL}/${FILE}"
done

# Download the final .zip descriptor
ZIP_FILE="BlendedMVS1.zip"
echo "Downloading $ZIP_FILE..."
wget -c "${BASE_URL}/${ZIP_FILE}"

echo "All files downloaded."

Reference the BlendedMVS dataset subsets

master

BlendedMVS is preprocessed into three subsets for MVS networks. Note that the original BlendedMVS low-res dataset is often sufficient for most research experiments.
