Abstract: The practicality of 3D object pose estimation remains limited for many applications due to the need for prior knowledge of a 3D model and a training period for new objects. To address this limitation, we propose an approach that takes a single image of a new object as input and predicts the relative pose of this object in new images without prior knowledge of the object’s 3D model and without requiring training time for new objects and categories. We achieve this by training a model to directly predict discriminative embeddings for viewpoints surrounding the object. This prediction is done using a simple U-Net architecture with attention and conditioned on the desired pose, which yields extremely fast inference. We compare our approach to state-of-the-art methods and show it outperforms them both in terms of accuracy and robustness.

2. Datasets

By default, all the datasets and experiments are saved at $ROOT_DIR as defined in this user's config.

We provide both pre-rendered datasets and scripts to render the datasets from scratch:

Option 1: Download pre-rendered datasets from our HuggingFace hub:

# Download all the datasets:
python -m src.scripts.download_preprocessed_shapenet

Option 2: Render the datasets from scratch:

# Download ShapeNet models:
python -m src.scripts.download_shapenet

# Generate poses:
python -m src.scripts.generate_poses_shapenet

# Render images and templates:
python -m src.scripts.render_images_shapenet
python -m src.scripts.render_template_seen_shapenet
python -m src.scripts.render_template_unseen_shapenet

Here is the structure of $ROOT_DIR after downloading:

├── $ROOT_DIR
