Evaluation of 3D reconstruction performance on the Tower of London dataset, reporting metrics such as Nc (feature count), Np (point count), MRE (mean reprojection error), and reconstruction time (T and TR).

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) | Tower of London |
| Metric | Feature Count (Nc) |
| 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

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

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

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

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

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