Abstract:
A system for distinguishing similar three dimensional cabinet faces, comprising:a first laser source for creating a first profile stripe across at least a portion of cabinet face in a first direction;a first camera for capturing an image of the first profile stripe;control means for matching the image of the first profile stripe to a prestored profile stripe image indicating a particular style code for said cabinet face;a second laser source for creating a second profile stripe across at least a portion of the cabinet face in a second direction;a leading sensor for detecting a leading edge of the cabinet face;a trailing sensor for detecting a trailing edge of the cabinet face; anda second camera, triggered by said leading sensor and said trailing sensor, for capturing a leading profile stripe and a trailing profile stripe of a plateau region of said cabinet face, said control means determining if a cathedral style cabinet face is present if said leading profile stripe differs from said trailing profile stripe by a threshold value.
