How to inspect glass for defects with computer vision

How can a glass maker or fabricator use computer vision to check sheets, panels and containers?

Train a model on the plant own images of glass, lit from behind or at an angle so flaws stand out, so it can mark likely chips, cracks, scratches, bubbles, stones, edge damage and coating marks. Each mark points to the piece and the spot on it, so a trained inspector can look closely and decide whether to pass, rework or reject it. The model only flags pieces and spots worth a second look; it never passes a piece on its own, and the existing quality and safety glazing checks stay in place.

What this means in practice

Set up fixed cameras with backlighting or angled lighting at the inspection point so flaws show clearly
Collect images of pieces that inspectors have already passed or rejected, for each product and thickness
Label the defect types the quality team tracks, plus clean examples of each product
Send only flagged pieces and spots to a trained inspector, who confirms or rejects each mark
Add reviewed images back into training whenever a new product, coating or line speed comes in

How Lid Vizion approaches it

We start with the business decision and operating context, define ownership and measurable milestones, then use configuration, integrations, automation, or custom software only where each earns its place.
