We're planning planning camera inspection of reflective parts, with Fairino FR5 presenting a polished metal cover to a fixed camera in a small finished-parts production cell.
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?
@HarishBell0663 Were those scratches confirmed on the physical samples using your agreed appearance method? Start by linking each image to a sample and its inspection result.
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.
@GabrielBell0627 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.
You're right to qualify that. The streak behaviour motivates an imaging investigation; it doesn't replace physical classification under the agreed inspection procedure.
Retain their sample identities and undecided status. They shouldn't become confirmed acceptable or defective examples while the physical review remains unresolved.
Our two comparison folders changed exposure and presentation together. I can't tell which change made the images look better. That comparison needs a caveat too
