We're planning planning camera inspection of reflective parts, with Fairino FR10 presenting a polished metal cover to a fixed camera in a precision metal-parts inspection area. 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?
Bright streaks move when we present the part differently

@SaraBarnes0548 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.
20分@DavidAbbott0084 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.
15分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.
14分@DavidAbbott0084 A scratch's visibility can change with presentation too. Don't let 'moving streak' quietly become the rule for relabelling something acceptable.

@LeoAdams0101 You're right to qualify that. The streak behaviour motivates an imaging investigation; it doesn't replace physical classification under the agreed inspection procedure.
16分I've settled the review method: physical reference checks plus controlled image comparisons. That answers where to start; whether our inspection concept is suitable still depends on the resulting evaluation.
16分You've settled the starting method, with inspection suitability still tied to the physical-reference and controlled-image evaluation.
