Paper Abstract

A fully integrated surface inspection system which uses a canputer generated solid model of a part is described. Inspection of the physical part is performed by an active stereo imaging system, one of the most practical vision methods for making measure-faits cn a smooth mamfactumd part. A mathematical treatment of the triangulation process using pinhole camera models is developed and yields an estimate of the measurement accuracy available from the system. The pan angle distance betueen camera and projector, as well as location and slope of the surface to be inspected, determines the minimum width and mininun depth of a detectable flaw. This system provides a user friendly surface inspection method for ccuputer modeled manufactured parts.
