Anomaly Factory 3D: A Modular Framework for Diverse Pseudo-Anomaly Synthesis in Unsupervised 3D Anomaly Detection
arXiv:2606.29181v1 Announce Type: cross Abstract: Detecting and localizing defects in 3D point clouds is challenging because abnormal samples are scarce and diverse, while training is often limited to normal data. We propose Anomaly Factory 3D (AF3AD), a modular framework that synthesizes diverse pseudo-anomalies from normal point clouds to expand the training data for unsupervised 3D anomaly detection methods that rely on pseudo-anomalies. AF3AD uses a center-conditioned parametric deformation model defined in local PCA frames, with kernel-controlled spatial falloff, anisotropy, directional g
The increasing sophistication of AI models and the critical need for robust anomaly detection in complex 3D environments, coupled with data scarcity, drives innovation in pseudo-anomaly synthesis.
This framework significantly reduces the barrier for training effective 3D anomaly detection systems, critical for quality control, industrial automation, and potentially autonomous systems.
The ability to generate diverse and realistic 3D anomalies from limited normal data enables better model generalization and deployment in real-world scenarios where defects are rare but impactful.
