APPLICATION SCENARIOS

6 real-world scenarios, one at a time

Blister: Missing Pills / Damage / Misload

High-Speed Real-Time Blister Pack Inspection

Blister packaging is the last line of protection before a drug meets the outside world — missing pills or damage directly affect efficacy and compliance.

Capsule Appearance & Color Mismatch

Capsule Defect Detection (80 Classes)

Capsule appearance defects come in many forms, making this one of the most experience-dependent steps in manual quality control for formulation.

Foil Seal & Embossing

Blister Foil Seal Inspection

The integrity of a foil seal and the consistency of its embossing directly relate to a drug's stability through its shelf life.

Label & Batch Code OCR

Inline Label OCR & Serial Code Verification

Drug labels carry batch number, expiry date, and traceability code — the first checkpoint for regulatory compliance.

Packaging Compliance Check

Pharmaceutical Packaging Compliance Verification

Drug packaging must simultaneously satisfy multiple compliance requirements — sealing, labeling, batch numbers, serialized traceability.

Vials: Cracks / Foreign Matter / Fill Level

Vial & Ampoule Light Inspection

Fill level, seal integrity, and glass fragments are the three most critical quality metrics on a sterile filling line.

Case studies

Pharma · visual inspection to packaging

From transparent particles in injectables to blister misses and label OCR — fewer false positives and rejects, fast go-live on few samples, compliant and auditable.

Scene · injectable AVI

A sterile-injectable plant · particle vs bubble

ChallengeBubbles vs real particles and glass glare vs cracks are very hard to tell apart; legacy AVI can reject up to 20% of good units.

SolutionAI-AOI adds a deep-learning re-judge to visual inspection, with APDT few-shot learning even when defect samples are scarce.

Vials and Ampoules: Guarding Fill Level, Seal, and Glass Fragments Under High-Speed Inspection

After filling and sealing vials and ampoules, a sterile injectables plant must verify fill level, seal integrity, and clear particles at speed. DaoAI AI-AOI high-speed inspection catches fill deviation, seal defects, and glass fragments together, with few-shot for rare defects, GMP-auditable throughout.

FAQ

Pharma · AI Visual Inspection FAQ

What quality items can AI vision inspect in pharma?

It covers vial and ampoule fill and seal, visible particles in injectables (telling bubbles from true foreign matter), multi-class capsule appearance defects, high-speed blister inspection, and label OCR with serialization.

Bubbles and real particles look alike in injectables, how does AI tell them apart?

DaoAI distinguishes motion trajectory and morphology with multi-frame dynamics and deep models, separating bubbles from true particles to cut both false rejects and escapes.

Under GMP, can AI inspection meet data integrity and audit traceability?

Yes. DaoAI supports on-premise deployment, traceable results and image archiving, and with label OCR and serialization it fits GMP data-integrity and anti-counterfeit traceability needs.

Blister and capsule lines are very fast, can AI inspect every unit?

Yes. DaoAI is optimized for high-speed blister and capsule inspection, checking every unit inline for missing pieces, breakage, color variation and multi-class appearance defects, replacing manual visual checks.
