RaSFNet: Ray-aligned and Scan-aware Fusion Network for LiDAR Semantic Segmentation

LiDAR point cloud semantic segmentation is a fundamental component of 3D perception for autonomous driving and robotics. Projection-based methods map 3D point clouds into 2D representations for feature extraction using 2D networks. However, aggregating multiple points during projection can obscure geometric differences...
