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.

Upgrade to BlendedMVG

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++):

Dataset         Resolution (768 x 576) Resolution (2048 x 1536) Supplementaries
BlendedMVS            low-res set (27.5 GB)     high-res set (156 GB)     textured meshes (9.42 GB), other images (7.56 GB)
BlendedMVS+ low-res set (81.5 GB)         -       -
BlendedMVS++ low-res set (80.0 GB)   -     -   

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

Dataset Structure

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.

What you can do with BlendedMVS(G)?

Please refer to following repositories on how to apply BlendedMVS(G) on multi-view stereo and feature detector/descriptor networks:

Tasks             Repositories                                          
Multi-view stereo MVSNet & R-MVSNet
Descriptors & Detectors GL3D & ASLFeat & ContextDesc & GeoDesc  

Except for the above tasks, we believe BlendedMVS(G) could also be applied to a variety of geometry related problems, including, but not limited to:

  • Sparse outlier rejection (OANet, tested with the original GL3D)
  • Image retrieval (MIRorR, tested with the original GL3D)
  • Single-view depth/normal estimation
  • Two-view disparity estimation
  • Single/multi-view camera pose regression

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).


2020 April 13:

  • Upgrade to BlendedMVG dataset!

2020 April 13:

  • 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.
