Sparse Voxel Meets View: Bridging Local Geometry and Global Semantics via Linear Attention in Place Recognition

Achieving accurate LiDAR-based place recognition is a crucial step towards reliable autonomous navigation, as it enables robust loop closure and global localization without GPS. However, existing 3D point cloud descriptors often give up fine local geometry for broad semantic context. We propose SBC-Net, a dual-branch a...
