# 3D Semantic Segmentation on SynLiDAR to SemanticSTF (val) Source: [3D Semantic Segmentation on SynLiDAR to SemanticSTF (val)]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:10:55.728Z Evaluation of 3D Semantic Segmentation performance on the validation split of the SynLiDAR to SemanticSTF dataset, reporting class-specific IoU metrics alongside performance under specific fog (D-fog, L-fog) and precipitation (Rain, Snow) conditions, and overall mIoU. 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 Semantic Segmentation | | Dataset (including any stated split) | SynLiDAR to SemanticSTF (val) | | Metric | mIoU (D-fog) | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 16 of 16 | | 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 (D-fog)](): Higher is better; unit: PERCENT. - [Car IoU](): Higher is better; unit: PERCENT. - [BI.CLE IoU](): Higher is better; unit: PERCENT. - [MT.CLE IoU](): Higher is better; unit: PERCENT. - [Truck IoU](): Higher is better; unit: PERCENT. - [Oth-V IoU](): Higher is better; unit: PERCENT. - [Person IoU](): Higher is better; unit: PERCENT. - [BI.CLST IoU](): Higher is better; unit: PERCENT. - [MT.CLST IoU](): Higher is better; unit: PERCENT. - [Road IoU](): Higher is better; unit: PERCENT. - [Parki.
