We're planning checking cosmetic metal surfaces with a fixed camera, 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?
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.
@EllaBarnes0555 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.
@EllaBarnes0555 A scratch's visibility can change with presentation too. Don't let 'moving streak' quietly become the rule for relabelling something acceptable
