Machine Vision Usage 1

[chad09]

I am working on a project to detect twist in shaped wire in the neighborhood of .1146 in width and .098 in hieght. My initial though is to do this using a vision system so I could keep the "twist detecter" out of harms way and out of the operators way also. Does anyone have experience doing something similiar? This would be on a continious system running <200 Ft/Min.

It can be done with video if price is no object...

Consider since this is a fixed shape, using a measuring system that measures one side and can then see elongation or fore-shortening if the wire begins to twist.

I would try something like a giant microscope with large relief to keep it away from the wire. Shine a bright light on the wire from the far side then behind the lens monitor the light attenuation. This would allow very fast detection with little to no computing as compared to a vision system which takes a TON of expensive computing that goes up rapidly as desired response time goes down.
