PolarBEVPlace: Rotation-Robust LiDAR Place Recognition via Radial Distortion-Aware Polar Transform
LiDAR-based place recognition is fundamental to loop closure and global localization in SLAM. Bird’s Eye View (BEV) projection has emerged as an effective paradigm for 3D point cloud processing, yet rotation robustness remains expensive: prior approaches either discretize SO(2) at <inline-formula><tex-math notation="La...
