Abstract

The measurement of geometrical parameters using image measurement technology is used widely in the industrial test and measurement. Usually a work-piece is measured mostly by a larger aperture system, whose aperture is not smaller than the work-piece. To a large work-piece, however, it is not practical to make so large an aperture and to keep accurate. A novel method named One Point and One Line (OPOL) working on 2D image connection is proposed here, through which parts of images about the work-piece sampled at first can be connected by the computer so that a total image containing abundant information should come into being. And on the basis of the total image, all of the measuring tasks are carried out quickly and efficiently by pre0established manmade feature objects and implementing subpixel analysis based on polynomial interpolation and polyfitting.
