Machine vision is a technical system designed to mimic human vision. In industrial settings, machine vision refers to the computer “vision” used to control automated manufacturing equipment. Although machine vision systems differ by product, four key elements remain the same: a digital camera, sensor, computer and special image processing software.

Machine vision can be used for multiple purposes over the length of an assembly line. It can be used to measure, count, inspect goods, or to read serial numbers. Machine vision has replaced workers in many jobs where humans are likely to err as a result of distraction or fatigue. Machine vision is also installed in those applications in which a robot arm or AGV needs to be guided.
Computer vision relies on digital cameras and pattern recognition software. Although machine vision has improved significantly in the past few years, computers are still incapable of the same kind of adaptable vision as humans. For this reason, machine vision systems are usually programmed to fulfill those assignments that require consistent repetition of the same task.
