Much as I love machine vision, I recognize there are some things it can’t do. It can’t for instance, tell what capsules are in a pill bottle. Yes, it might be able to give you their size, shape and color, but is that enough?
When it comes to pharmaceuticals, I’m not one to take chances, which is why I enjoyed “Machine Vision and Raman Spectroscopy” by Kenneth W Chapman, posted on The Imaging Source blog September 9th, 2011.
This describes the addition of Raman technology to a machine vision system so as to determine exactly what’s in those pill bottles. This might seem a somewhat narrow niche, but I don’t think it takes too much imagination to see how the concept could be applied to more industrial problems. How about checking on the composition of a surface coating, for example?
Machine vision can’t do it all, so let’s keep our eyes open for complementary sensor technologies that can help us avoid saying “No.”
