This page is for downloading and using the pretrained models in PyTorch. You can also try a demo in your browser or train your own models.

Installation

git clone https://github.com/EPFL-VILAB/omnidata 
cd omnidata/omnidata_tools/torch
conda create -n testenv -y python=3.8
source activate testenv
pip install -r requirements.txt

You can see the complete list of required packages in omnidata-tools/torch/requirements.txt. We recommend using virtualenv for the installation.

Pretrained Models

You can download our pretrained models for surface normal estimation and depth estimation. For each task there are two versions of the models--a V1 used in the paper, and a stronger V2 released in March 2022.

Network Architecture

Version 2 models (stronger than V1)

These are DPT architectures trained on more data using both 3D Data Augmentations and Cross-Task Consistency. Here's the list of updates in Version 2 models:

Angular Error % Within t Relative Normal
Method Training Data Mean Median 11.25 22.5 30 AUC_o AUC_p
Hourglass OASIS 23.91 18.16 31.23 59.45 71.77 0.5913 0.5786
UNet (v1) Omnidata 24.87 18.04 31.02 59.53
71.37 0.6692 0.6758
DPT (v2) Omnidata 24.16 18.23 27.71 60.95
74.15 0.6646 0.7261
Human (Approx.) - 17.27 12.92 44.36 76.16 85.24 0.8826 0.6514

Version 1 models

The surface normal network is based on the UNet architecture (6 down/6 up). It is trained with both angular and L1 loss and input resolutions between 256 and 512.

The depth networks have DPT-based architectures (similar to MiDaS v3.0) and are trained with scale- and shift-invariant loss and scale-invariant gradient matching term introduced in MiDaS, and also virtual normal loss. You can see a public implementation of the MiDaS loss here. We provide 2 pretrained depth models for both DPT-hybrid and DPT-large architectures with input resolution 384.

Download pretrained models

sh ./tools/download_depth_models.sh
sh ./tools/download_surface_normal_models.sh

These will download the pretrained models for depth and normals to a folder called ./pretrained_models.

Run our models on your own image

After downloading the pretrained models, you can run them on your own image with the following command:

python demo.py --task $TASK --img_path $PATH_TO_IMAGE_OR_FOLDER --output_path $PATH_TO_SAVE_OUTPUT

The --task flag should be either normal or depth. To run the script for a normal target on an example image:

python demo.py --task normal --img_path assets/demo/test1.png --output_path assets/
