[net.general] Cheap Computer Vision ?

apj@ukc.UUCP (A.P.Jeavons) (08/03/83)

I would like some help from the wise men of netland.
I need advice about computer vision, more specifically what is a good cheap
opto-receptor for making an artificial eye.  The resolution needs to be 
enough to detect say something about the size of a ping-pong ball at 0.2-3.0
metres.  I've thought of cheap second hand video cameras (colour is not needed)
, any suggestions? No analysis of the image need be done by the receptor, it
just needs to give an output that is analysable somehow.  Cost is a bit of
a problem, ideally less than $300 if possible.  Also I would be grateful for
any references to the latest work in computer vision.  Responses via mail or
on followups please.
