Our planned checking cosmetic metal surfaces with a fixed camera in a cosmetic components workshop has Fairino FR5 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.
@DineshBennett0734 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.
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.
@NaomiArcher0419 A scratch's visibility can change with presentation too. Don't let 'moving streak' quietly become the rule for relabelling something acceptable.
@NaomiBaker0506 Correct. I meant a reason to investigate the imaging, not a new defect label. Physical acceptance stays with the agreed inspection method.
@NaomiArcher0419 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.
