| # DL3DV-Depth-DA3-Aligned |
|
|
| Per-frame depth annotations for the DL3DV dataset, produced by |
| **Depth-Anything-3 (DA3)** and then **aligned** to each scene's sparse depth |
| from the original DL3DV reconstruction. We use this refined dataset for 3D world generation and reconstruction in our [**Puffin-World**](https://github.com/KangLiao929/Puffin). |
|
|
| ## Sample Videos |
|
|
| Each clip is a 1×3 comparison — **RGB | Original Depth | Our Aligned Depth** — |
| with depth rendered by *vision banana* representation. It shows |
| how the DA3-aligned depth (right) densifies and cleans up the original sparse |
| depth (middle). |

| ## Directory structure |
|
|
| The archive mirrors the source DL3DV layout — one `.zip` per |
| scene, grouped into bucket folders `1K`–`7K` (`<bucket>/<scene_hash>.zip`). |
| The scene hashes match DL3DV and [DL3DV-Absolute-Camera](https://huggingface.co/datasets/KangLiao/DL3DV-Absolute-Camera), so |
| depth pairs 1:1 with the source frames / absolute camera annotations. |
|
|
| Each `<scene_hash>.zip` unpacks to: |
|
|
| ``` |
| dense/ |
| └── depth_da3/ |
| ├── frame_00001.npy |
| ├── frame_00002.npy |
| ├── frame_00003.npy |
| └── ... |
| ``` |
|
|
| Each `frame_NNNNN.npy` is a float32 depth map — `np.load(...)` returns an |
| array of shape `(H, W)` (e.g. `(536, 954)`), one per source frame, indices |
| matching the DL3DV frames. |
|
|
| ## How the depth was produced |
|
|
| - **Predicted** with Depth-Anything-3 (DA3). |
| - **Aligned** to the sparse depth of the original DL3DV dataset (per-scene |
| alignment against the sparse reconstruction), so each scene's DA3 depth is |
| brought into a consistent, scale-aligned space. |
|
|
| ## Usage |
|
|
| ```python |
| import numpy as np |
| depth = np.load("dense/depth_da3/frame_00001.npy") # (H, W) float32 |
| ``` |
|
|
| ## Notes |
|
|
| - ~6,377 scenes; each `.npy` frame ≈ 2 MB (float32), stored losslessly. |
| - Companion camera annotations: [DL3DV-Absolute-Camera](https://huggingface.co/datasets/KangLiao/DL3DV-Absolute-Camera). |
|
|
| ## Caption Pipeline |
|
|
| Beyond the aligned dataset, we also release **a complete captioning pipeline** for annotating the dense depth map for arbitrary datasets, aligning with the sparse depth, and visualizing the corresponding depth maps. The pipeline is available in our [GitHub repository](https://github.com/KangLiao929/Puffin). |
