APPLICATION SCENARIOS

6 real-world scenarios, one at a time

Drum / Bag Seal Inspection

Inline Drum & Bag Seal Inspection

The seal integrity of chemical drums and bags is directly tied to transport safety and product shelf life.

Gauge & Level Reading

Online Gauge & Liquid-Level Reading Recognition

Gauge and liquid-level readings are the primary data source for key chemical process parameters.

Labels & Hazmat Markings

False-Alarm Reduction for Printed Film / Label Coils

The accuracy of hazmat labels is tied to transport compliance and on-site safety response speed.

Line Patrol & Leak Detection

Production Line Patrol & Leak Detection

Chemical production lines have many pipe connections spread over a wide area — catching leaks and drips in time is directly tied to safe operation.

Surface: Bubbles / Impurities / Color Mismatch

Unsupervised Anomaly Detection on Textured Surfaces

Quality control of complex textured surfaces is one of the most experience-dependent steps before chemical materials ship.

Web / Film Continuous Defects

Coil Coating Pinhole & Agglomeration Detection

Micron-scale 3D defects like pinholes and agglomeration in web and film materials directly affect barrier, insulation, and appearance performance.

Low-contrast Coating Boundary Detection: Dominant-channel Enhancement, 95%+ Recall on Faint Edges

A coating web plant struggled with near-zero color difference between coating and substrate, leaving edges, skips and shrinkage nearly invisible in grayscale. DaoAI's dominant-channel enhancement amplifies the faint signal, lifting boundary defect recall above 95%.

Glass/Nonwoven Surface Defect Detection: Few-shot Go-live, 94%+ Recall

A materials plant had scarce, highly variable defect samples on glass and nonwoven. DaoAI combined few-shot learning with good-only anomaly detection for fast go-live, reaching 94%+ recall on semi-transparent and weak-texture surfaces.

FAQ

Chemical / Materials · AI Visual Inspection FAQ

What defects does AI vision detect in chemicals and materials?

It covers 3D inspection of web pinholes and agglomerates, low-contrast coating boundaries, false-call reduction on printed film, few-shot defects on glass and nonwovens, and unsupervised texture anomaly detection.

Material surfaces are continuous textures with formless defects, how does AI inspect them?

DaoAI uses unsupervised anomaly detection to learn the normal texture distribution and flags deviations, finding novel flaws without enumerating defect types.

On fast web lines, how are tiny pinholes and agglomerates kept from escaping?

DaoAI 3D inspection captures pinholes, agglomerates and bumps on fast-moving webs, with real-time localization for continuous full-width coverage.

Low-contrast coatings and printed film generate many false calls, how are they reduced?

DaoAI separates true defects from normal printing and coating variation with deep models, sharply cutting false calls so limited review effort targets real issues.
