## Per-threshold F-scores (aligned)

| Threshold | Precision | Recall | F-score |
| --- | --- | --- | --- |
| 1mm | 0.0109 | 0.0084 | 0.0095 |

## Alignment transform

- Scale recovered: `0.925399` (deviation from metric: 0.0746)
- Rotation angle undone: `2.597` deg
- Translation norm: `0.0462` m
- ICP iterations: `9`, final RMSE `0.005685` m

_The rotation angle is the magnitude of the alignment rotation the solver had to
apply; the reconstruction frame is arbitrary, so it is not an error against a
reference. For symmetric objects the transform is defined only up to the object's
symmetry group._
