Abstract
A video imaging system for sequentially measuring the dimensions or tolerances of a plurality of fasteners. The system includes a feed gate in combination with a reciprocating chuck, the latter moving each fastener, one at a time, into the field of view of a pair of orthogonally-oriented cameras. A pair of orthogonally-oriented back-lights, one each being directly opposite the field of view of one of the cameras, silhouettes each fastener, and defines a camera image that is digitized for producing fastener dimensions. The orthogonal relationship of the cameras enables the true fasteners position to be calculated relative to each camera.
