Evaluation of 3D Reconstruction performance on the ETH Fountain Small-Scale dataset, reporting metrics such as Track Length and Reprojection Error.

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) | ETH Fountain Small-Scale |
| Metric | Track Length |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 8 of 8 |
| 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

- [Track Length](<https://www.sota2.com/research/sota/3d-reconstruction-on-eth-fountain-small-scale.md?metric=Track%20Length>): Higher is better; unit: SCALAR.

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