New LiDAR OOD Detection Method Improves Autonomous Driving Safety

Researchers have developed a new framework called Relative Energy Learning (REL) for detecting out-of-distribution (OOD) objects in 3D LiDAR point clouds, a crucial task for autonomous driving safety. Unlike previous methods that struggled with distinguishing anomalies, REL uses the energy gap between in-distribution and out-of-distribution logits to improve robustness. To overcome the lack of OOD data during training, the team introduced a lightweight data synthesis strategy called Point Raise, which generates auxiliary anomalies by perturbing existing point clouds. Experiments on SemanticKITTI and the STU benchmark showed REL significantly outperforms existing methods. AI
