Abstract

A three dimensional machine vision system, based on-a phase measuring version of moire topography, is described. By rotating an object in front of the system, surface co-ordinates can be acquired from many thousands of points around the periphery of that object. A computational method for comparing the dimensions of an object with its design specification is described. The application of this method is restricted to the subset of objects which can be described in terms of simple primitive shapes.
