Machine Vision (MV) is the application of Computer Vision to industry and manufacturing. Whereas computer vision is mainly focused on machine-based image processing, machine vision most often requires also digital input/output devices and computer networks to control other manufacturing equipment such as robotic arms.
Machine Vision is a subfield of engineering that incorporates computer science, optics, mechanical engineering, and industrial automation.
One of the most common applications of Machine Vision is the inspection of manufactured goods such as semiconductor chips, automobiles, food and pharmaceuticals. Just as human inspectors working on assembly lines visually inspect parts to judge the quality of workmanship, so machine vision systems use Digital Cameras, Smart Cameras and Image Processing software to perform similar inspections.
