VT-3DAD: Cross-Category 3D Anomaly Detection via Visual-Text Normal Space Alignment
Researchers have introduced VT-3DAD, a novel framework for detecting anomalies in 3D point clouds across different categories. This training-free method leverages both visual and textual information from CLIP to identify deviations from normal patterns. By aligning visual features with text-encoded normal anchors, VT-3DAD significantly improves accuracy and reduces variability in anomaly detection tasks, outperforming existing visual-only baselines.
