Abstract
An image recognition system using a light-section method which has versality and does not shorten the service life of light projector means. Projection of light from a light source onto a workpiece is continued between the time when a measuring command is issued and the time just after light has been converged by the automatic aperture control mechanism of a television camera. An image processing unit processes an image picked up by the television camera just after the convergence of light by the automatic aperture control mechanism so as to obtain three dimensional configuration data on the workpiece.
