Fundamentals of Machine Vision
Harley R. Myler · SPIE eBooks · 1998
Machine vision systems have two primary elements: the camera, which serves as the eye of the system, and a computer video image analyzer. Lighting is also an important consideration. The camera, which may be a standard vidicon or solid-state, scans a scene at a rate of 1/60 seconds. A stream of information from the picture elements (pixels) of the camera representing a two dimensional image of the scene is fed serially into the camera interface, digitizer and processing computer.
