What is Machine Vision?

Machine vision enables the automated visual inspection of manufactured products for quality and process control. Image is analyzed to determine the part's location, any defects, and dimensions. The results are then communicated to other equipments, such as programmable logic controllers, robots or motion controllers to perform a specific function.
