# 3EED: Ground Everything Everywhere in 3D — Dataset Card

A cross-platform, multi-modal 3D visual grounding dataset spanning **vehicle**, **drone**, and **quadruped** platforms, with synchronized **RGB**, **LiDAR**, and **language** annotations. This page documents how to obtain and organize the dataset from HuggingFace and how to connect it with the training/evaluation code in the 3EED repository.

- Project Page: https://3eed.github.io
- Code (Baselines & Evaluation): https://github.com/iris0329/3eed
- Paper: https://arxiv.org/ (coming soon)

## 1. What’s Included

- Platforms: `vehicle`, `drone`, `quad` (quadruped)
- Modalities: LiDAR point clouds, RGB images, language referring expressions, metadata
- Splits: train/val files per platform under `splits/`
- Task: 3D visual grounding (language → 3D box)

## 2. Download

You can download via:
- HuggingFace CLI:
  ```bash
  pip install -U "huggingface_hub[cli]"
  huggingface-cli download 3EED/3EED --repo-type dataset --local-dir ./3eed_dataset
  ````

- Python:

  ```python
  from huggingface_hub import snapshot_download
  snapshot_download(repo_id="3EED/3EED", repo_type="dataset", local_dir="./3eed_dataset")
  ```
- Git (LFS):

  ```bash
  git lfs install
  git clone https://huggingface.co/datasets/3EED/3EED 3eed_dataset
  ```

## 3. Directory Structure

- Place or verify the files under `data/3eed/` in your project. A minimal expected layout (paths shown relative to the repo root):
  
  ```
  data/3eed/
  ├── drone/                     # Drone platform data
  │   ├── scene-0001/
  │   │   ├── 0000_0/
  │   │   │   ├── image.jpg
  │   │   │   ├── lidar.bin
  │   │   │   └── meta_info.json
  │   │   └── ...
  │   └── ...
  ├── quad/                      # Quadruped platform data
  │   ├── scene-0001/
  │   └── ...
  ├── waymo/                     # Vehicle platform data
  │   ├── scene-0001/
  │   └── ...
  └── splits/                    # Train/val split files
      ├── drone_train.txt
      ├── drone_val.txt
      ├── quad_train.txt
      ├── quad_val.txt
      ├── waymo_train.txt
      └── waymo_val.txt
  ```


## 4. Connect to the Codebase

- Clone the code repository:
  
  ```bash
  git clone https://github.com/iris0329/3eed
  cd 3eed
  ```

- Link or copy the downloaded dataset to `data/3eed/`:
  
  ```bash
  # Example: if your dataset is in ../3eed_dataset
  ln -s ../3eed_dataset data/3eed
  ```

Now you can follow the **Installation**, **Custom CUDA Operators**, **Training**, and **Evaluation** sections in the GitHub README:

* Train on all platforms:

  ```bash
  bash scripts/train_3eed.sh
  ```
* Train on a single platform:

  ```bash
  bash scripts/train_waymo.sh   # vehicle
  bash scripts/train_drone.sh   # drone
  bash scripts/train_quad.sh    # quadruped
  ```
* Evaluate:

  ```bash
  bash scripts/val_3eed.sh
  bash scripts/val_waymo.sh
  bash scripts/val_drone.sh
  bash scripts/val_quad.sh
  ```

Remember to set the correct `--checkpoint_path` inside the evaluation scripts.

## 5. Data Splits

We provide official splits under `data/3eed/splits/`:

* `*_train.txt`: training scene/frame indices for each platform
* `*_val.txt`: validation scene/frame indices for each platform

Please keep these files unchanged for fair comparison with the baselines and reported results.

## 6. Usage Tips

* Storage: LiDAR+RGB data can be large; ensure sufficient disk space and use Git LFS for partial sync if needed.
* IO Throughput: For faster training/evaluation, place frequently used scenes on fast local SSDs or use caching.
* Reproducibility: Use the exact environment files and scripts from the code repo; platform unions vs. single-platform runs are controlled by the provided scripts.

## 7. License

* Dataset license: **Apache-2.0** (see the header of this page).
* The **code repository** uses **Apache-2.0**; refer to the LICENSE in the GitHub repo.

If you plan to use, redistribute, or modify the dataset, please review the dataset license and any upstream source licenses (e.g., Waymo Open Dataset, M3ED).
