BlendedMVS is a large-scale MVS dataset for generalized multi-view stereo networks. The dataset contains 17k MVS training samples covering a variety of 113 scenes, including architectures, sculptures and small objects.

BlendedMVG, a superset of BlendedMVS, is a multi-purpose large-scale dataset for solving multi-view geometry related problems. Except for the 113 scenes in BlendedMVS dataset, we follow its blending procedure to generate 389 more scenes (originally shown in GL3D) for BlendedMVG. The training image number is increased from 17k to over 110k.

BlendedMVG and its preceding works (BlendedMVS and GL3D) have been applied to several key 3D computer vision tasks, including image retrieval, image feature detection and description, two-view outlier rejection and multi-view stereo.

For MVS networks, BlendedMVG is preprocessed and split into 3 smaller subsets (BlendedMVS, BlendedMVS+ and BlendedMVS++):

Experiments in BlendedMVS paper were conducting using the BlendedMVS low-res-dataset. In most cases, the low-res dataset would be enough.

BlendedMVS(G) dataset adopts MVSNet input format. Please structure your dataset as listed below after downloading the whole dataset:

PID here is the unique project ID listed in the BlendedMVG_list.txt file. We provide blended images with and without masks.  For detailed file formats, please refer to MVSNet.

BlendedMVS(G) could also be applied to a variety of geometry related problems, including, but not limited to:

• Multi-view/Two-view stereo (MVSNet & R-MVSNet)
• Descriptors & Detectors & Matching (GL3D & ASLFeat & ContextDesc & GeoDesc & OANet)
• Multi-view/Single-view camera pose estimation
• Novel View Synthesis (Evaluation of NeRF and 3DGS related works)
• Single-view depth/normal estimation (Depth Anything & Depth Pro)
• Transformer-based 3D Vision (DUSt3R & VGGT)

Feel free to modify the dataset and adjust to your own tasks!

• Online augmentation should be implemented by users themselves. An example for tensorflow users could be found in MVSNet. An example for pytorch users could be found in CasMVSNet_pl
• The number of selected source images for a given reference image might be smaller than 10 (when parsing pair.txt).
• The depth_min and depth_max in ground truth cameras might be smaller or equal to zero (very few, when parsing *_cam.txt).
• The rendered depth map and blended images might be empty as the textured mesh model is not necessarily to be complete (when dealing with *.pfm and *.jpg files).

• Upgrade to BlendedMVG dataset!

• Upload BlendedMVS textured mesh models
• Upload BlendedMVS high-res dataset
• Upload input and rendered images (low-res)
• Fix bug on multi-texture mesh rendering, update BlendedMVS low-res dataset.

• Fix download links

• Download links by Github release
• Update usages
