Introduction ❖Definition ➢ Machine vision (MV) is the technology and methods used to provide imagingbased automatic inspection and analysis for such applications as automatic inspection, process control, and robot guidance, usually in industry. ➢ Machine vision is a term encompassing a large number of technologies, software and hardware products, integrated systems, actions, methods and expertise. ➢ Machine vision as a systems engineering discipline can be considered distinct from computer vision, a form of computer science. ➢ It attempts to integrate existing technologies in new ways and apply them to solve real world problems. 3 1. Introduction ❖Definition ➢ The overall machine vision process includes planning the details of the requirements and project, and then creating a solution. During run-time, the process starts with imaging, followed by automated analysis of the image and extraction of the required information. 4 1.
