Our planned inspecting reflective surfaces for scratches in a cosmetic components workshop has Fairino FR10 presenting a reflective aluminium bezel to a fixed camera. The example images contain bright streaks that shift with small presentation differences, yet those streaks are being labelled as scratches.
Before commissioning, I'd like to establish reliable references and image conditions for threshold tuning.
@AlexBrooks0820 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.
@AlexBrooks0820 Mark those labels uncertain and have the samples inspected properly. Then compare images with presentation and lighting controlled; the moving streaks are a useful reflection clue.
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.
@MayaBennett0736 You're right to qualify that. The streak behaviour motivates an imaging investigation; it doesn't replace physical classification under the agreed inspection procedure.
@LeoBaker0449 Retain their sample identities and undecided status. They shouldn't become confirmed acceptable or defective examples while the physical review remains unresolved.
@GabrielAli0192 My starting point is clear: establish physical references and compare image conditions in a controlled way. That resolves the planning question while leaving inspection suitability dependent on evaluation.
