Researchers have introduced ArtiAD, a new benchmark designed for articulated 3D anomaly detection, addressing limitations in existing methods that struggle with objects possessing joints. The benchmark includes over 15,000 point clouds across 39 categories, featuring detailed annotations for joint configurations and anomaly types. To tackle this challenge, a novel Shape-Pose-Aware Signed Distance Field (SPA-SDF) method was proposed, which disentangles pose variations from structural defects. SPA-SDF demonstrated superior performance compared to rigid-based approaches on both seen and unseen articulation configurations. AI
