# MV-STRIDE — Multi-View Spatial Reasoning QA Dataset

Hierarchical (Level I/II/III) multi-view spatial-reasoning QA data generated by the [MV-STRIDE](https://github.com/co1dspring/MV-STRIDE) pipeline from two scene sources: **Infinigen** (synthetic, procedurally generated) and **ScanNet++** (real scanned scenes). Every sample asks a multiple-choice spatial question about 2–3 images of the same scene taken from different camera viewpoints.

## Layout

- `annotations/<source>/<version>_{atomic,stage1,stage3}.json` — QA samples; each sample:
  `messages` (user: `<image><image>Question + Options`, assistant: answer), `images` (**relative to this dataset repo**, `images/<source>/...`), `category`, `scene_name`, `data_source`.
- `images/<source>/...` — the images referenced by the annotations (per-scene dirs mirror the source layout; Infinigen scenes also carry `scene_metadata.json`, ScanNet++ scenes `scene_metadata_new.json`).
- `configs/` — the exact `qa_config_*.json` used to generate each split.

## Files

| source | scenes | file | samples | role |
|---|---|---|---|---|
| infinigen | 439 | `Infinigen_MultilevelCategories_20260403_sampled_MCA_Multistage_atomic.json` | 253,400 | full set, all levels, single-turn |
| infinigen | 439 | `Infinigen_MultilevelCategories_20260403_sampled_MCA_Multistage_stage1.json` | 147,382 | SFT split (stage-1 scene pool) |
| infinigen | 439 | `Infinigen_MultilevelCategories_20260403_sampled_MCA_Multistage_stage3.json` | 36,631 | Level III only, RL split (stage-3 scene pool) |
| scannetpp | 137 | `ScannetppIphone_MultilevelCategories_20260313_sampled_MCA_Multistage_atomic.json` | 284,325 | full set, all levels, single-turn |
| scannetpp | 137 | `ScannetppIphone_MultilevelCategories_20260313_sampled_MCA_Multistage_stage1.json` | 167,889 | SFT split (stage-1 scene pool) |
| scannetpp | 137 | `ScannetppIphone_MultilevelCategories_20260313_sampled_MCA_Multistage_stage3.json` | 21,608 | Level III only, RL split (stage-3 scene pool) |

Total: **537,725** single-turn QA samples (Level I perception + Level II cross-view + Level III reasoning incl. MSR).

Load with the `datasets` library:

```python
from datasets import load_dataset
ds = load_dataset("json", data_files="annotations/*/*_stage1.json")
# images are paths relative to this repo root; join before reading
```
