Patent attributes
A method and apparatus for verifying location and orientation of a piece attached to a work surface for s manufacturing a workpiece is disclosed. A controller is programmed with design data for manufacturing steps. Multiple layers of ply are sequentially layered over a work surface. An imaging system capable of redirecting a field of view along the work surface is provided. A light projector is provided for projecting reference features onto the work surface. The light projector projects a reference feature to a known location relative to the piece applied to the work surface within the field of view of the imaging device. The imaging device generates an image of the reference features projected by the light projector and of the piece applied onto the work surface. The controller compares the location of the piece on the work surface with the design data validating accurate placement of the piece.
