Evaluation of 3D Scene Alignment performance on the WikiEarth meta-to-reference dataset, reporting metrics such as ΔR°\_I↔M.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | 3D Scene Alignment |
| Dataset (including any stated split) | WikiEarth meta-to-reference |
| Metric | Delta R (I\<-\>M) |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 5 of 5 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Delta R (I\<-\>M)](<https://www.sota2.com/research/sota/3d-scene-alignment-on-wikiearth-meta-to-reference.md?metric=Delta%20R%20(I%3C-%3EM)>): Lower is better; unit: SCALAR.
