We're planning checking cosmetic metal surfaces with a fixed camera, with Fairino FR5 presenting a polished metal cover to a fixed camera in a robot-presented camera station. 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.
I've found that some labels were assigned from the images themselves. The samples are still available, but those labels have no corresponding physical inspection results, making the reference circular.
@ReeceBennett0732 Keep the image-only labels uncertain pending physical inspection. A controlled comparison of lighting and presentation can then investigate whether the moving streaks indicate reflection effects.
@CallumChan1056 Keep them explicitly undecided, with the sample link. Don't use them as confirmed examples of either class until the physical review settles them.
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.
