Evaluation of trajectory estimation accuracy and computational efficiency for models tested on the TbD-3D Challenging 50 dataset, focusing on line segment detection methods.

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 | Trajectory Estimation via Line Segment Detection |
| Dataset (including any stated split) | TbD-3D Challenging 50 |
| Metric | Avg Error (px) |
| Unit | SCALAR |
| Direction | Lower 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

- [Avg Error (px)](<https://www.sota2.com/research/sota/trajectory-estimation-via-line-segment-detection-on-tbd-3d-challenging-50.md?metric=Avg%20Error%20(px)>): Lower is better; unit: SCALAR.

- [Std Dev Error (px)](<https://www.sota2.com/research/sota/trajectory-estimation-via-line-segment-detection-on-tbd-3d-challenging-50.md?metric=Std%20Dev%20Error%20(px)>): Lower is better; unit: SCALAR.

- [Runtime (s)](<https://www.sota2.com/research/sota/trajectory-estimation-via-line-segment-detection-on-tbd-3d-challenging-50.md?metric=Runtime%20(s)>): Lower is better; unit: TIME.
