Evaluation of 3D Object Detection performance on the DAIR-V2X dataset, reporting standard AP metrics (mAP@.5, mAP@.7) alongside communication efficiency metrics (KB usage and relative efficiency).

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 Object Detection |
| Dataset (including any stated split) | DAIR-V2X |
| Metric | mAP@.5 |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 9 of 9 |
| 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

- [mAP@.5](<https://www.sota2.com/research/sota/3d-object-detection-on-dair-v2x-detection-and-efficiency.md?metric=mAP%40.5>): Higher is better; unit: PERCENT.

- [mAP@.7](<https://www.sota2.com/research/sota/3d-object-detection-on-dair-v2x-detection-and-efficiency.md?metric=mAP%40.7>): Higher is better; unit: PERCENT.

- [Per-Agent Size (KB)](<https://www.sota2.com/research/sota/3d-object-detection-on-dair-v2x-detection-and-efficiency.md?metric=Per-Agent%20Size%20(KB)>): Lower is better; unit: SIZE.

- [Total Size (KB)](<https://www.sota2.com/research/sota/3d-object-detection-on-dair-v2x-detection-and-efficiency.md?metric=Total%20Size%20(KB)>): Lower is better; unit: SIZE.

- [Relative Efficiency (%)](<https://www.sota2.com/research/sota/3d-object-detection-on-dair-v2x-detection-and-efficiency.md?metric=Relative%20Efficiency%20(%25)>): Higher is better; unit: PERCENT.
