# iPhone360 Dataset (Simple Version)

iPhone360 is a benchmark dataset for 360° reconstruction of dynamic objects from monocular video, introduced in the paper:

> **4DGS360: 360° Gaussian Reconstruction of Dynamic Objects from a Single Video**
> Jae Won Jang, Yeonjin Chang, Wonsik Shin, Juhwan Cho, Nojun Kwak
> [Project Page](https://jaewon040.github.io/4dgs360/) · [arXiv](https://arxiv.org/abs/2603.21618)

## Dataset Description

iPhone360 features real-world dynamic scenes captured with an iPhone, where **test cameras are positioned at significantly different angles from training views**. This enables evaluation of 360° reconstruction capabilities that existing datasets cannot provide.

## Dataset Versions

This dataset is distributed in two versions:

- **`iPhone360 simple_version`** (this folder) — RGB/depth/mask/camera/points/splits data plus lightweight VDA depth and lidar alignment, with the heavy 4DGS360-specific intermediate preprocessing outputs (2D/3D tracks, track-anything masks, AnchorTAPIP3D refined depth/tracks, cached scene-normalization tensors) excluded. Much smaller download.
- **[`iPhone360-4dgs360 preprocessed version`](https://huggingface.co/datasets/mipal/iPhone360-4dgs360)** — includes *all* preprocessing outputs required to reproduce 4DGS360 training and evaluation end-to-end. Large footprint.

**If you're quickly adapting iPhone360 to a new paper/method, we recommend starting here with `simple_version`** and evaluating on it first, rather than downloading the full `preprocessed_version`. Only fall back to `preprocessed_version` if you specifically need to reproduce 4DGS360's own training pipeline.

## Scenes

| Scene | Description |
|-------|-------------|
| `block2` | Dynamic object scene |
| `goat` | Dynamic object scene |
| `jacket` | Dynamic object scene |
| `jelly` | Dynamic object scene |
| `pull-up` | Dynamic object scene |
| `walk-around` | Dynamic object scene |

## Data Structure

Each scene contains:
- `rgb/` — RGB frames
- `depth/` — Depth maps
- `masks/` — Object masks
- `camera/` — Camera parameters
- `splits/` — Train/test split definitions
- `points.npy` — Initial point cloud
- `dataset.json` / `scene.json` / `metadata.json` — Scene metadata
- `flow3d_preprocessed/` — Lightweight preprocessed data (video depth, lidar-aligned depth); does **not** include the 4DGS360-specific tracks/cache/refined-depth outputs found in `preprocessed_version`
