Evaluation of HD Map Reconstruction performance on the specific frontal 50m x 50m test split of the Argoverse dataset, utilizing geometric accuracy metrics like Chamfer Distance, RandLoss, and MMD, alongside urban structure metrics (density, reach, connectivity).

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 | HD Map Reconstruction |
| Dataset (including any stated split) | Argoverse frontal 50m x 50m (test) |
| Metric | Chamfer Distance |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 6 of 6 |
| 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

- [Chamfer Distance](<https://www.sota2.com/research/sota/hd-map-reconstruction-on-argoverse-frontal-50m-x-50m-test.md?metric=Chamfer%20Distance>): Lower is better; unit: SCALAR.

- [RandLoss](<https://www.sota2.com/research/sota/hd-map-reconstruction-on-argoverse-frontal-50m-x-50m-test.md?metric=RandLoss>): Lower is better; unit: SCALAR.

- [MMD](<https://www.sota2.com/research/sota/hd-map-reconstruction-on-argoverse-frontal-50m-x-50m-test.md?metric=MMD>): Lower is better; unit: SCALAR.

- [Urban Density ARE](<https://www.sota2.com/research/sota/hd-map-reconstruction-on-argoverse-frontal-50m-x-50m-test.md?metric=Urban%20Density%20ARE>): Lower is better; unit: SCALAR.

- [Urban Reach ARE](<https://www.sota2.com/research/sota/hd-map-reconstruction-on-argoverse-frontal-50m-x-50m-test.md?metric=Urban%20Reach%20ARE>): Lower is better; unit: SCALAR.

- [Urban Connectivity ARE](<https://www.sota2.com/research/sota/hd-map-reconstruction-on-argoverse-frontal-50m-x-50m-test.md?metric=Urban%20Connectivity%20ARE>): Lower is better; unit: SCALAR.
