| # MessyKitchens cameras |
|
|
| [cameras.json](cameras.json) contains the final fitted cameras for all 1,503 prepared views. |
| The schema is `partprobe3d.messykitchens.cameras.v1`. |
| The `views` dictionary uses the same view keys as the prepared dataset manifest. |
|
|
| | Field | Meaning | |
| | --- | --- | |
| | `scene` | Original scene identifier | |
| | `source_view` | Original photograph identifier | |
| | `native_size` | Image width and height in pixels, in that order | |
| | `projection_intrinsics` | The 3 × 3 intrinsic matrix for the native image | |
| | `camera_to_world` | The 4 × 4 rigid transform from camera coordinates to world coordinates | |
|
|
| World coordinates match the prepared GT meshes in meters. |
| Camera axes point right, down, and forward for positive x, y, and z. |
| Native pixel centers use integer coordinates, starting at `(0, 0)`. |
| The intrinsic matrix uses these native pixel coordinates. |
|
|
| For column vectors, `camera_to_world` maps `[x, y, z, 1]` from the camera frame to the world frame. |
| Its inverse provides the world-to-camera transform. |
| The top-left 3 × 3 block contains rotation. |
| The final column contains translation in meters. |
|
|
| These cameras result from GT-assisted silhouette fitting and constitute estimated calibration. |
| All views passed local convergence and native overlap plateau checks. |
| The file preserves the final numeric values without rounding. |
| Fit diagnostics, candidate cameras, and optimizer records remain outside this clean export. |
|
|
| This file supplements the existing evaluation archives. |
| Their per-view registration records retain the earlier camera estimates. |
