Computer Vision For Quality Inspection: What It Catches And What It Misses
Vision systems are excellent at consistent defects and poor at novel ones. Knowing the difference decides whether your ROI case survives contact with the line.

This article is part of our ongoing technical series. Our engineers write about the decisions they make on live projects — what worked, what cost more than expected, and what they would do differently next time.
Why this matters
Most published guidance on this topic assumes conditions that rarely exist in practice: unlimited budget, greenfield sites and teams with spare capacity. The reality is usually an existing operation that cannot stop, a fixed capital allocation, and a team already stretched.
The approach described here is written for those constraints. It prioritises sequencing — what to do first so that later stages become cheaper — over technical completeness.
Where teams usually go wrong
The most common failure is starting with the most visible problem instead of the most constraining one. Visible problems attract budget; constraining problems decide whether that budget produces a return.
If you cannot measure the baseline, you cannot prove the improvement — and a project that cannot prove improvement will not get funded twice.
Instrumentation first, automation second. It feels slower for the first two months and pays back for the following two years.
