My company has several of the IV-Navigator vision cameras that we use for nut detection on an area that is very similar on the Gray scale. We have a lot of trouble with accuracy and repeat-ability to find good and bad parts with these cameras. I really feel like they aren't adequate for our application. But I wanted some other opinions before I go through validating a different system to use as our standard. Does anyone have any thoughts on the best way to detect this reliably with the IV-Navigator cameras?
