| # DeVA — RoboCasa (processed) |
|
|
| Processed **RoboCasa** data for [DeVA](https://github.com/Mq-Zhang1/deva), a robot |
| video-world model with affordance + depth physical guidance. Derived from |
| [robocasa/robocasa](https://github.com/robocasa/robocasa) — |
| **please cite the original benchmark as well**. |
|
|
| | | | |
| |---|---| |
| | Episodes | 1,199 | |
| | Frames | 316,995 | |
| | Video | 448 × 448, 16 fps (3 views on a 2×2 grid) | |
| | Views | `agentview_left`, `agentview_right`, `eye_in_hand` | |
| | Action dim | 7 (absolute) | |
| | Proprio state | not included | |
| | Size | 56 GB | |
|

|
| `videos/` tiles the views on the grid given by `dataset_info.json::tile` — the |
| bottom-right cell is empty: |
|
|
| ``` |
| [[agentview_left, agentview_right], |
| [eye_in_hand, null ]] |
| ``` |
|
|
| ## Affordance / depth `.npz` |
|
|
| Both are keyed by **canonical view name** (never by tile position), one array per view: |
|
|
| | | affordance | depth | |
| |---|---|---| |
| | key | `<view>` | `<view>` | |
| | dtype | `float16` | `float16` | |
| | shape | `[T, 224, 224]` | `[T, 224, 224]` | |
| | range | raw, un-normalized | `[0, 1]` | |
| | note | loader resizes to 128×128, then per-frame max-normalizes | per-view per-clip min-max applied at export | |
|
|
| `T` equals the episode's video frame count, so aux arrays index by absolute frame. |
| The validity mask is derived from the tile grid (`null` cells are invalid) and is not stored. |
|
|
| **Depth source** — DepthAnything (ViT-L) disparity, converted as `depth = 1 / disparity`; |
| **higher value = farther**. No percentile clip is applied: the range is set by the |
| farthest pixel, so agentview content occupies roughly the lower half of `[0, 1]` and |
| never saturates. |
|
|
| **Affordance source** — simulator oracle contacts rendered as Gaussian heatmaps. |
