Why OpenCV for this
The retraining pipeline is the deliverable people forget. Conditions drift, new defect types appear, and a model nobody can retrain quietly rots over a year.
OpenCV is strongest at classical techniques still outperform models for many well-defined vision tasks. For computer vision that matters because the failure modes of this kind of system tend to cluster exactly there.
The honest trade-off: hand-tuned pipelines are brittle when conditions change. We say that up front because a stack chosen for fashion rather than fit becomes someone's migration project two years later. We build the smallest thing that proves the case, put it in front of real users, and expand only what earns its keep.
Six weeks to something running in production, not six quarters to a strategy document.

We are not a reseller for OpenCV and hold no commission on this choice. Where a different option fits your workload better, the recommendation will say so. That is the entire value of asking us.
What is included
- Data collection protocol and labelling workflow
- Model training against your real conditions and lighting
- Edge deployment with offline tolerance
- Precision and recall reported per defect class
- Integration with MES, PLC or alerting systems
- Retraining pipeline as conditions drift
Questions
How much training data do we need?
It depends on defect variability, but a few hundred well-labelled examples per class is a realistic starting point. We design the collection protocol first so the data you gather is actually usable.
Does it run without internet?
Yes. We deploy at the edge with offline tolerance, syncing results when connectivity returns, essential in most plant environments.
What accuracy can we expect?
We report precision and recall per defect class against a held-out set from your line, rather than a single headline number. The honest figure varies by class and we show which ones are hard.
Alternatives for computer vision
Same capability, different stack. Each page states its own trade-off.
