We are working with a Keyence image dimension measuring system. This is essentially an automated optical comparator. I figured that maybe people familiar with Vision techniques could assist with a basic question.
We have deemed the machine incapable of measuring I.D. size dimensions. The repeatability is not there. I think that for a machine like this, I.D. size should be quite fundamental.
I have heard that backlight is the way to go and I have found a post on here from a while ago stating that the minimal possible amount of backlight is preferred to reduce a "halo effect". Does anybody else have any theory/suggestions for I.D. size or for accurate measurements in general?
Thank you.
