Pattern Matching

DESIGNED BY: Young Solutions Inc.

Pattern matching was one of the first tools developed for vision systems. In its most basic form it is simply comparing and counting pixels against a master file. Pattern matching by itself has probably been responsible for selling more vision systems than any other software feature. It is incredibly simple to set up and demonstrate to a customer. When looking at a couple of sample parts in a quick demonstration it can promote a deceptive confidence in this vision tools ability to solve the problem at hand.Then when a customer integrates a camera in their process and they start looking at hundreds, or thousands of parts the weakness of using this tool exclusively becomes very apparent. There are very specific constraints which must be applied to use such a tool successfully.Clearly pattern matching is an important tool when applied correctly. Used in combination with other vision tools it can be utilized to develop very strong solutions in vision system integration..
