4D Radar Meets LiDAR and Camera: Cooperative Perception under Adverse Weather
Researchers have developed a new method for cooperative perception in autonomous driving that integrates 4D imaging radar to overcome the limitations of cameras and LiDAR in adverse weather conditions. This approach utilizes a Doppler-guided spatial attention mechanism for multi-agent fusion and has been tested on radar-camera and LiDAR-radar pipelines. The system demonstrated significant robustness improvements in fog and rain, with radar effectively replacing degraded LiDAR data, and has been validated on real-world datasets. AI
