Abstract: Machine vision is used in all walks of life widely now, mainly applied to automatic detection in measurement field. For measurement field, from the aspects of the number of applications, regional distribution, and applicants in the domestic and foreign, the patents of machine vision technology are analyzed in  several ways of camera calibration, image processing and practical application. The technology developing process is sort out and the research directions at home and abroad are compared, thus some suggestions are made for our countrys technology r&d in this field.
Key words: machine vision; measurement; camera calibration; image processing
