I spotted an interesting article in the July 2008 edition of ‘Quality Digest’ relating to the use of Cognex Checker for error-proofing. If you’re not familiar, the Checker is a low-end vision sensor that comes in under the Insight range. That means it’s inexpensive and has somewhat limited functionality. But, as the software comes from Cognex, it’s not a poor quality product.
I don’t want to steal content from ‘Quality Digest’, so let me instead give you this link: Cognex Checker application.
Careful readers will notice that the Engineer set up each sensor with a part location tool – to find the part in the image – and then referenced a simple inspection tool from that. That’s significant, because if you know Cognex you’ll know that their pattern finding tools are amongst the best in the business. So the message is; Checker might be inexpensive, but it can be a very powerful little tool.

This is an example of an interesting low cost off the shelf but useful solution!
I recently wrote an article in the IT magazine that i reproduced on my blog: http://indradhanush-laal.blogspot.com/
Since you are an expert in vision and this article is about vision I thought of pointing it to you. I think you may find it interesting. Your comments are welcome.
