Optical And Digital Processing Techniques In A Machine Vision Metrology System
Abstract
Described here are the optical and image processing aspects of a computer vision system for automated precision measurement of manufactured objects. A multi-magnification, multi-path telecentric imaging system with multiple illumination sources provides broad utility. A general method of deriving digital filters for image analysis is presented.
