Industrial image processing by means of an image recognitionintegrated system

摘要

An overview of the requirements for industrial applications ofcomputer vision is given. A method called multilevel input binarytemplate matching, which applies binary template matching to gray-levelimages, is presented. With this method, a vision system can be tailoredto the difficulty of the individual computer-vision application whilemaintaining high speed and high reliability in all cases. A full customVLSI specially designed for binary template matching is discussed. Thisdedicated VLSI chip, called IRIS, has a configurable kernel up to a sizeof 1024 elements for 1-D or up to 32×32 elements for 2-D, and hasintegrated line buffers. Some application examples from the field ofindustrial automation are presented
