Super4DR: 4D Radar-centric Self-supervised Odometry and Gaussian-based Map Optimization
Zhiheng Li, Weihua Wang, Qiang Shen +2
Conventional SLAM systems using visual or LiDAR data often struggle in poor lighting and severe weather. Although 4D radar is suited for such environments, its sparse and noisy poi…
