3D-Only Anomaly Detection in Polyurethane Manufacturing
This case study highlights CMDR-IAD's effectiveness in real-world industrial scenarios where only 3D geometric data is available, successfully identifying subtle cutting irregularities and shape distortions.
Challenge: Geometric Defects in Polyurethane Cuts
Polyurethane cutting operations often produce subtle geometric defects like irregular cuts, burrs, or gaps. Traditional 2D vision systems struggle with these, especially when RGB data is noisy or unavailable, requiring a robust 3D-only solution.
CMDR-IAD Solution:
CMDR-IAD's dedicated 3D reconstruction branch was deployed. This pathway leverages Point-MAE features and a custom 3D decoder to reconstruct normal geometric patterns. Anomalies are detected by measuring deviations from these learned patterns.
Results:
The 3D-only variant achieved a strong 92.6% I-AUROC and 92.5% P-AUROC on the real-world polyurethane cutting dataset. This demonstrates its ability to reliably detect and localize geometry-dominant defects without needing RGB information, validating its practical utility in challenging industrial environments.
