# ARKitScenes-SpatialLM Dataset

ARkitScenes dataset preprocessed in SpatialLM format for oriented object bouding boxes detection with LLMs.

## Overview

This dataset is derived from [ARKitScenes](https://github.com/apple/ARKitScenes) **5,047 real-world indoor scenes** captured using Apple's ARKit framework, preprocessed and formatted specifically for [SpatialLM](https://github.com/manycore-research/SpatialLM) training.

## Data Extraction

Point clouds and layouts are compressed in zip files. To extract the files, run the following script:

```bash
cd arkitscenes-spatiallm
chmod +x extract.sh
./extract.sh
```

## Dataset Strucutre

```bash
arkitscenes-spatiallm/
├── arkitscenes_train.json # Training conversations
├── arkitscenes_val.json # Validation conversations
├── dataset_info.json # Dataset metadata
├── split.csv # Train/val split mapping
├── pcd/ # Point cloud data
│ └── .ply
├── layout/ # Scene layout annotations
│ └── .txt
└── extract.sh # Extraction script
```

The `arkitscenes_train.json` and `arkitscenes_val.json` dataset follows the **SpatialLM format** with ShareGPT-style conversations:

```json
{
  "conversations": [
    {
      "from": "human",
      "value": "<point_cloud>Detect boxes. The reference code is as followed: ..."
    },
    {
      "from": "gpt",
      "value": "<|layout_s|>bbox_0=...<|layout_e|>"
    }
  ],
  "point_clouds": ["pcd/scene_id.ply"]
}
```
