Abstract

PURPOSE: To provide an object measuring system by coded grid projection, in which a grid having its respective slit addresses coded by color variation is projected upon an object to re read out a slit image so that it may become complex on the basis of the color change of the respective slit images, thereby to accomplish the measurement of the shape of an object.
