# InternScenes

  <p>
      <strong>InternScenes</strong> is a large-scale interactive indoor scene dataset with realistic layouts. This dataset comprises approximately <strong>40,000 diverse scenes</strong> and <strong>1.96M 3D objects</strong> that cover <strong>15 common scene types</strong> and <strong>288 object classes</strong>, which is roughly <strong>10 times larger than existing datasets</strong>.

## 🔑 Key Features
  <div class="section">
    <p>InternScenes integrates a wide variety of scenes, and particularly, preserves small items for complex layouts, resolve collisions, and further incorporates interactive objects, thus ensures:</p>
    <ul>
      <li>📊 <strong>Large scale</strong>: 40,000 diverse scenes including 1.96M 3D objects covering 288 object classes.</li>
      <li>🚪 <strong>Realistic layouts</strong>: preserving massive small objects to strictly align with real-world scanned scenes.</li>
      <li>🕹️ <strong>Interactivity</strong>: 20% interactive objects inside covering 16 common types, such as cabinets, microwaves, ovens, and fridges.</li>
    </ul>
  </div>

  ### Which tasks will benefit from our dataset?
  <ul>
   <li> ✅ 3D scene reconstruction
   <li> ✅ 3D scene understanding
   <li> ✅ Scene layout generation
   <li> ✅ Embodied navigation
  </ul>

## ⚙️ Getting Started

### Download the Dataset 
To download the full dataset, you can use the following code. If you encounter any issues, please refer to the official Hugging Face documentation.
```
# Make sure you have git-lfs installed (https://git-lfs.com)
git lfs install

# When prompted for a password, use an access token with write permissions.
# Generate one from your settings: https://huggingface.co/settings/tokens
git clone https://huggingface.co/datasets/OpenRobotLab/InternScenes

# If you want to clone without large files - just their pointers
GIT_LFS_SKIP_SMUDGE=1 git clone https://huggingface.co/datasets/OpenRobotLab/InternScenes
```

If you only want to download a specific dataset, such as `splitaloha`, you can use the following code.
```
# Make sure you have git-lfs installed (https://git-lfs.com)
git lfs install

# Initialize an empty Git repository
git init InternScenes
cd InternScenes

# Set the remote repository
git remote add origin https://huggingface.co/datasets/OpenRobotLab/InternScenes

# Enable sparse-checkout
git sparse-checkout init

# Pull the data
git pull origin main
```
