3DIdent Dataset

We introduce 3Dident, a dataset with hallmarks of natural environments (shadows, different lighting conditions, 3D rotations, etc.). A preliminary version of the dataset is released along with our pre-print.

3DIdent dataset example images

You can access the dataset here. The training and test datasets consists of 250000 and 25000 samples, respectively. To load, you can use the ThreeDIdentDataset class defined in datasets/threedident_dataset.py.
