Computer Vision Defect Detection on Production Lines
Defect detection places a camera where a piece passes and flags the ones that look wrong. It covers surface marks, missing components, short packs and misprinted labels, and works alongside your inspector.
Conditions for detection
The fault must be visible in a photograph. A scratch, a dent, a wrong colour or a missing cap can be seen. A hairline crack under paint or a material property cannot. Position matters as much: the piece must pass the camera at a repeatable angle, since a model trained on one view performs poorly on another.
How a system is built and proven
The inspector stays
The system catches obvious and repetitive faults. That is its job. Judgement calls, new fault types and anything involving feel or sound stay with your people. Treating the system as a replacement risks shipping a fault nobody was watching for.
Frequently asked questions
How accurate is defect detection likely to be?
It depends on your line and is not known until the system is tested there, so shadow running comes before any commitment. Accuracy is reported as missed defects and false rejects separately, since the two cost you differently.
Does it need to connect to our line equipment?
Only if you want it to stop or divert a piece. Many plants start with a flag and a log, then connect a reject mechanism once they trust the readings.
What if we make hundreds of different products?
Then a general model is unlikely to suit. Start with the one or two lines where rejection costs the most, prove it there, and extend by product family.
How do we collect defective samples?
Usually by keeping rejects aside for a few weeks and photographing them as they occur. Plants with a low defect rate need longer, and that collection period is part of the plan.

What happens after you share your requirements
- A senior engineer reads your answers. Nobody phones first.
- Within one business day you get a written note: what we understood, what we would start with, and the questions we still have.
- If it fits, a proposal follows with the order of work, what we need from you and what you receive at each step.
- No call is booked and nothing is paid until you have read the note. Your details stay with us.
