Patent attributes
A method of verifying placement of a piece on a work surface is disclosed. An imaging device and an illumination system are electronically interconnected with a computer. The illumination system projects indicia onto a work surface for indicating a location for placement of a piece on the work surface. An indicator is provided to the piece that includes light emission displaying fluorescent wavelengths when illuminated for distinguishing the piece form the work surface. The piece is placed upon the work surface at a location indicated by the laser indicia. The illumination system illuminates the piece presenting a visible contrast between the piece and the work surface enabling the imaging device to distinguish the piece from the work surface. The imaging device signals the controller a location of the piece for the controller to verify accurate placement of the piece.
