ABSTRACT:
Apparatus for examining the shape and/or dimensions of an object wherein an object is fed to a test station (12) on a stepping conveyor (14), the object is illuminated within the test station and scanned by two linear charge-coupled camera devices (18, 20) acting in mutually perpendicular directions across and along the conveyor. Logic circuitry processes the video signals to provide raw measurement signals fed into a microprocessor for analyzing the signals and for providing control signals for a downstream reject mechanism.
