More on tool selection

Over at Control Engineering there’s a gentleman by the name of Charlie Masi who blogs on matters of interest to Control Engineers. And as machine vision is a tool that many such engineers wish to use, he touches on the subject from time to time.

Back in October of 2007 he posted an interesting piece titled “How should control engineers use machine vision?” This discusses how a camera acquires data from an area rather than a single point, and so can provide much more information than can a simple sensor. However, sometimes all that’s needed is the sensor. He goes on to mention how a new generation of sensors, (Cognex Checker and others,) has a level of intelligence that allows them to ‘recognize’ what they’re detecting.

It’s a good article. Take a look.
