Evaluation of LiDAR Semantic Segmentation performance on the unseen scene split of the SemanticKITTI dataset, reporting mean Intersection over Union (mIoU) and per-class IoU scores for key categories.

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 | LiDAR Semantic Segmentation |
| Dataset (including any stated split) | SemanticKITTI (unseen scene) |
| Metric | mIoU |
| Unit | PERCENT |
| 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

- [mIoU](<https://www.sota2.com/research/sota/lidar-semantic-segmentation-on-semantickitti-unseen-scene.md?metric=mIoU>): Higher is better; unit: PERCENT.

- [Car IoU](<https://www.sota2.com/research/sota/lidar-semantic-segmentation-on-semantickitti-unseen-scene.md?metric=Car%20IoU>): Higher is better; unit: PERCENT.

- [Bicycle IoU](<https://www.sota2.com/research/sota/lidar-semantic-segmentation-on-semantickitti-unseen-scene.md?metric=Bicycle%20IoU>): Higher is better; unit: PERCENT.

- [Motorcycle IoU](<https://www.sota2.com/research/sota/lidar-semantic-segmentation-on-semantickitti-unseen-scene.md?metric=Motorcycle%20IoU>): Higher is better; unit: PERCENT.

- [Truck IoU](<https://www.sota2.com/research/sota/lidar-semantic-segmentation-on-semantickitti-unseen-scene.md?metric=Truck%20IoU>): Higher is better; unit: PERCENT.

- [Pedestrian IoU](<https://www.sota2.com/research/sota/lidar-semantic-segmentation-on-semantickitti-unseen-scene.md?metric=Pedestrian%20IoU>): Higher is better; unit: PERCENT.

- [Terrain IoU](<https://www.sota2.com/research/sota/lidar-semantic-segmentation-on-semantickitti-unseen-scene.md?metric=Terrain%20IoU>): Higher is better; unit: PERCENT.
