This repository contains a re-implementation of the code for the paper Probing the 3D Awareness of Visual Foundation Models (CVPR 2024) which presents an analysis of the 3D awareness of visual foundation models.

We recommend using Anaconda or Miniconda. To setup the environment, follow the instructions below.

conda create -n probe3d python=3.9 --yes
conda activate probe3d
conda install pytorch=2.2.1 torchvision=0.17.1 pytorch-cuda=12.1 -c pytorch -c nvidia 
conda install -c pytorch -c nvidia faiss-gpu=1.8.0
conda install -c conda-forge nb_conda_kernels=2.3.1

pip install -r requirements.txt
python setup.py develop

pip install protobuf==3.20.3    # weird dependency with datasets and google's api
pre-commit install              # install pre-commit

Finally, please follow the dataset download and preprocessing instructions here.

We provide code to train the depth probes and evaluate the correspondence. All experiments use hydra configs which can be found here. Below are example commands for running the evaluations with the DINO ViT-B/16 backbone.

# Training single-view probes
python train_depth.py backbone=dino_b16 +backbone.return_multilayer=True
python train_snorm.py backbone=dino_b16 +backbone.return_multilayer=True

# Evaluating multiview correspondence 
python evaluate_navi_correspondence.py +backbone=dino_b16
python evaluate_scannet_correspondence.py +backbone=dino_b16
python evaluate_spair_correspondence.py +backbone=dino_b16

Coming soon.

We thank Prafull Sharma, Shivam Duggal, Karan Desai, Junhwa Hur, and Charles Herrmann for many helpful discussions. We also thank Alyosha Efros, David Fouhey, Stella Yu, and Andrew Owens for their feedback.

We would also like to acknowledge the following repositories and users for releasing very valuable code and datasets:

• GeoNet for releasing the extracted surface normals for full NYU.
