We're planning presenting reflective components for surface inspection, with Fairino FR5 presenting a reflective aluminium bezel to a fixed camera in a robot-presented camera station.
Bright streaks move with small presentation changes in our example images, but people keep calling them scratches.
We haven't commissioned the cell.
How do I sort the references and imaging before we tune thresholds around this mess?
Getting consistent inspection evidence before commissioning

Check whether the suspected scratches were confirmed on physical samples under the agreed appearance procedure. Link each image to its sample identity and inspection result first.

Some labels came from the pictures alone. We still have the samples, but those labels aren't tied to physical inspection results. That's irritatingly circular.

Keep the image-only labels uncertain pending physical inspection. A controlled comparison of lighting and presentation can then investigate whether the moving streaks indicate reflection effects.

That clue needs a limit: presentation can also change how a real scratch appears. Movement in the image isn't enough to reclassify the sample as acceptable.
