Our planned planning camera inspection of reflective parts in a cosmetic components workshop has Fairino FR5 presenting a brushed stainless trim plate to a fixed camera. The example images contain bright streaks that shift with small presentation differences, yet those streaks are being labeled as scratches. Before commissioning, I'd like to establish reliable references and image conditions for threshold tuning.
A fixed camera, small presentation changes, very different streaks

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.

@LeoChen1145 I've found that some labels were assigned from the images themselves. The samples are still available, but those labels have no corresponding physical inspection results, making the reference circular.
9分@BethAllen0324 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.

A scratch's visibility can change with presentation too. Don't let 'moving streak' quietly become the rule for relabelling something acceptable.

@HazelAli0223 You're right to qualify that. The streak behaviour motivates an imaging investigation; it doesn't replace physical classification under the agreed inspection procedure.

The inspection concept remains undecided because the available references and images don't establish reliable discrimination of the required defects.
23分@BethAllen0324 Your reason for holding the decision is clear: the current evidence doesn't establish reliable identification of the required defects.
