MB-Loc: Multi-planar Bird's-eye-view Localization in outdoor LiDAR scenes
Researchers have developed MB-Loc, a new framework for multi-planar bird's-eye-view localization in outdoor LiDAR scenes. This method addresses computational inefficiency and viewpoint sensitivity in existing scene coordinate regression techniques. MB-Loc projects LiDAR scans into a 2.5D representation, enabling faster processing with standard 2D CNNs while retaining crucial 3D geometric information. The framework also incorporates a KL-regularized latent bottleneck for spatial uncertainty modeling and 3D spatial augmentations for rotation robustness, outperforming current state-of-the-art methods on the NCLT dataset at real-time inference speeds.
