Vision interface options

If you only use smart cameras, or Keyence vision systems, this doesn’t concern you. If however you’re a machine vision user who works with PC-based systems, read on.

The issue is interfaces. Now I have a strong feeling that more than 50% of users give no thought to how the image gets from camera to computer. Mostly likely they, or you, just pick up a camera with the required resolution and get to work.

That’s not a good idea. There are at least six interface standards, and they all have their strengths and weaknesses. Deciding which is best for your task means knowing what those are, which is why I suggest you read “Choosing a Vision Interface” by Jim Camillo and published in the April 2013 edition of Assembly magazine.

You’ll need to register to read the whole article, which I find irritating. (Isn’t it enough that I look at all the advertisements?) But that said, it’s a good, fact-filled read, so take a look.
