Evaluation of 3D Reconstruction performance using the Roman Forum dataset, reporting metrics such as Nc (feature count), Np (point count), MRE (mean reprojection error), and reconstruction time (T (s)).

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 Reconstruction |
| Dataset (including any stated split) | Roman Forum |
| Metric | Nc (Feature Count) |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 4 of 4 |
| 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

- [Nc (Feature Count)](<https://www.sota2.com/research/sota/3d-reconstruction-on-roman-forum.md?metric=Nc%20(Feature%20Count)>): Higher is better; unit: SCALAR.

- [Np (Point Count)](<https://www.sota2.com/research/sota/3d-reconstruction-on-roman-forum.md?metric=Np%20(Point%20Count)>): Higher is better; unit: SCALAR.

- [MRE (Mean Reprojection Error)](<https://www.sota2.com/research/sota/3d-reconstruction-on-roman-forum.md?metric=MRE%20(Mean%20Reprojection%20Error)>): Lower is better; unit: SCALAR.

- [Reconstruction Time (s)](<https://www.sota2.com/research/sota/3d-reconstruction-on-roman-forum.md?metric=Reconstruction%20Time%20(s)>): Lower is better; unit: TIME.

- [TR Time (s)](<https://www.sota2.com/research/sota/3d-reconstruction-on-roman-forum.md?metric=TR%20Time%20(s)>): Lower is better; unit: TIME.
