Paint and coating defect detection

The inspection point

A painted surface is where the customer reads quality first, so a dust inclusion, a run or an orange-peel patch directly affects perceived quality. The difficulty is that a glossy surface behaves like a mirror and reflects everything around it, which mixes the defect with the reflection.

How it runs on the line

Diffuse lighting brings the reflection under control and the unit is placed outside the angle of reflection. The model learns the texture of a good surface and flags the points that depart from it. The result reaches the line and the panel goes to rework.
