Benchmarking datasets for geometry estimation can be somewhat cumbersome to download. We provide instructions for the benchmarks we use below, and are happy to answer any questions.

HPatches

First, make sure that the "data/hpatches" path exists, e.g. by

ln -s place/where/your/datasets/are/stored/hpatches data/hpatches

Then run (if you don't already have hpatches downloaded)

bash scripts/download_hpatches.sh

Megadepth-1500 (LoFTR Split)

  1. We use the split made by LoFTR, which can be downloaded here https://drive.google.com/drive/folders/1nTkK1485FuwqA0DbZrK2Cl0WnXadUZdc. (You can also use the preprocessed megadepth dataset if you have it available)
  2. The images should be located in data/megadepth/Undistorted_SfM/0015 and 0022.
  3. The pair infos are provided here https://github.com/zju3dv/LoFTR/tree/master/assets/megadepth_test_1500_scene_info
  4. Put those files in data/megadepth/xxx

Megadepth-8-Scenes (DKM Split)

  1. The pair infos are provided in assets
  2. Put those files in data/megadepth/xxx

Scannet-1500 (SuperGlue Split)

We use the same split of scannet as superglue.

  1. LoFTR provides the split here: https://drive.google.com/drive/folders/1nTkK1485FuwqA0DbZrK2Cl0WnXadUZdc
  2. Note that ScanNet requires you to sign a License agreement, which can be found http://kaldir.vc.in.tum.de/scannet/ScanNet_TOS.pdf
  3. This benchmark should be put in the data/scannet folder
