Our planned checking cosmetic metal surfaces with a fixed camera in a robot-presented camera station has Universal Robots UR5e presenting a polished metal cover 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.
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.
@LinBennett0705 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.
