Machine vision systems are devices that capture and analyze visual information, and are used to automate tasks that require "seeing".
A camera lens and image sensor are used to capture images. Vision software analyzes what is being seen and communicates information to other equipment. Vision systems also require lighting and are configured by connecting them to a display device such as a computer monitor.
Vision systems can have a variety of physical forms, depending on the user’s need. Users can purchase vision software to use with their own camera and processor, or they can purchase a standalone unit that combines camera, processor and software into a single package.
