Chuan Cao, Xiaoning Wang, Wenqian Xi, Han Zhang, Weidong Chen, Jingchuan Wang

IROS 2025

4D imaging radar is a type of low-cost millimeter-wave radar(costing merely 10-20% of lidar systems) capable of providing range, azimuth, elevation, and Doppler velocity information. Accurate extrinsic calibration between millimeter-wave radar and camera systems is critical for robust multimodal per

SN-LiDAR: Semantic Neural Fields for Novel Space-time View LiDAR Synthesis

Yi Chen, Tianchen Deng, Wentao Zhao, Xiaoning Wang, Wenqian Xi, Weidong Chen +1

IROS 2025

Recent research has begun exploring novel view synthesis (NVS) for LiDAR point clouds, aiming to generate realistic LiDAR scans from unseen viewpoints. However, most existing approaches do not reconstruct semantic labels, which are crucial for many downstream applications such as autonomous driving
