Pretrained models

We provide huggingface demos for monocular surface normal estimation and depth estimation. You can load/run the models

import torch
# you may need to install timm for the DPT (we use 0.4.12)

# Surface normal estimation model
model_normal = torch.hub.load('alexsax/omnidata_models', 'surface_normal_dpt_hybrid_384')

# Depth estimation model
model_depth = torch.hub.load('alexsax/omnidata_models', 'depth_dpt_hybrid_384')

# Without pre-trained weights
model_custom = torch.hub.load('alexsax/omnidata_models', 'dpt_hybrid_384', pretrained=False, task='normal')

Previously, installing + using the models was more difficult. Using torch.hub.load is now the recommended way to use the models locally.

Dataset

You can download each component and modality individually or all at once with our download utility. MAIN DATA PAGE

conda install -c conda-forge aria2
pip install 'omnidata-tools'

omnitools.download point_info rgb depth_euclidean mask_valid fragments \
    --components replica taskonomy \
    --subset debug \
    --dest ./omnidata_starter_dataset/ \
    --name YOUR_NAME --email YOUR_EMAIL --agree_all

We ran our annotation pipeline on several collections of 3D meshes. The result is a 24-million-viewpoint multiview dataset comprising over 2000 scenes with the following labels for each image:

Per-Image Information

--components: Taskonomy, Hypersim, Replica, Google Scanned Objects in Replica, Habitat-Matterport3D, BlendedMVS, CLEVR
