We're planning presenting reflective components for surface inspection, with Universal Robots UR5e presenting a bright-finished enclosure faceplate to a fixed camera in a small finished-parts production cell. 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?
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.
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.
