# What Makes Good Synthetic Training Data for Zero-Shot Stereo Matching? (WMGStereo)

[Paper](https://huggingface.co/papers/2504.16930) | [GitHub](https://github.com/princeton-vl/InfinigenStereo)

**WMGStereo** is a procedural dataset generator specifically optimized for zero-shot stereo matching performance. This repository contains the WMGStereo-150k dataset, a large-scale synthetic training dataset featuring indoor, nature, and dense "flying" scenes.

## Dataset Download

You can download the dataset using the `huggingface-cli`:

```bash
pip install huggingface-cli
huggingface-cli download pvl-lab/WMGStereo --repo-type dataset
```

## Dataset Structure

The dataset file structure is as follows:

```
.
└── WMGStereo/
    ├── indoor/
    │   └── seed_num/
    │       └── frames/
    │           ├── Image/
    │           │   ├── camera_0
    │           │   └── camera_1
    │           ├── camview/
    │           │   ├── camera_0
    │           │   └── camera_1
    │           ├── disparity/
    │           │   └── camera_0
    │           ├── occ_mask/
    │           │   └── camera_0
    │           └── sky_mask/
    │               └── camera_0
    ├── flying/
    │   └── ...
    └── nature/
        └── ...
```

*   **Camera 0 and 1**: correspond to left and right camera frames, respectively. 
*   **Ground Truth**: We provide disparity, occlusion, and sky-region masks for the left camera.
*   **camview**: contains `.npz` files that contain a dictionary with indices `K`, `T`, `HW`, corresponding to calibration, translation, and resolution matrices.
