The Car's Radar Draws the Scene at 400 Frames a Second
StreamRPS labels spinning-radar data with completed LiDAR scenes, then performs streaming semantic and panoptic segmentation by sector.
Summary
StreamRPS labels spinning-radar data with completed LiDAR scenes, then performs streaming semantic and panoptic segmentation by sector.
Cameras and LiDAR can degrade in darkness or bad weather, while spinning radar remains available but difficult to interpret. StreamRPS pairs labels built from LiDAR scene completion with a radar-specific transformer that preserves range and angular structure. On the SAX and BOREAS datasets, the authors report at least a 1.4-point gain over the strongest evaluated baseline and throughput above 400 frames per second in a four-sector configuration. They also release manual annotations for 100 SAX scans. This is not an autonomous-driving safety certification, but it pushes radar from sparse detections toward real-time scene structure.
