RCVLA: 4D Radar-Grounded Semantic Reasoning and Trajectory Arbitration for Autonomous Driving

4D radar provides geometric and motion cues that complement visual semantics, but integrating it into vision-language-action (VLA) models requires both radar--language alignment for semantic reasoning and explicit use of radar measurements for trajectory refinement and selection. To support these capabilities, we const...

SRCDet: sparse fusion of surround-view radar and camera for 3D object detection

A query-based multimodal fusion framework, termed SRCDet, is proposed for camera-4D radar fusion, which achieves consistent improvements across nearly all metrics and low error rates in clear and adverse weather conditions, highlighting its practical adaptability to automotive-grade systems and effectiveness in safety-...
