DVT Cognex Vision
What is DVT Cognex Machine Vision?
Machine vision, in layman’s terms, is exactly that. It can be defined as machines with their own set of
eyes. Using their vision, machines inspect products for defects by detecting the presence or absence of parts, taking measurements, reading codes, etc. How it works may seem rather complicated at first
glance. However, with a little help from basic optics, it is not. The machine’s eye mainly looks for
changes in contrast and uses a 2-dimensional plane to do so. Our Vision Tools tell the camera (the machine’s eye) how to evaluate changes in contrast and in what direction to evaluate them. The camera then collects this information from the image and evaluates it following the user-defined rules. Because the camera’s actions are so dependent upon that change in contrast, it is imperative that you adjust your lighting such that the camera (or machine) can get a consistent and close look at the factory product.
