Abstract: A system and method for aligning projection of an optical indicia on a surface of a large object is disclosed. A reference is disposed in proximity to the object. The reference includes a plurality of markers spaced at intermittent locations. A projection system projects optical indicia onto the surface of the object. A detection system detects the markers disposed upon the reference and signals an image of the markers to a processor for the processor to register a location of the projection system relative to the reference. The reference is aligned with a feature disposed upon the object enabling registration of the markers to the object. A location of the projection system relative to the object is established enabling the projection system to project the optical indicia onto the object to a predetermined location.

Abstract: A method of identifying an item on a surface of a workpiece is disclosed. An optical device identifies an item on the surface of a workpiece. An item identification system includes a light projector and a photogrammetry system. One of the light projector and the photogrammetry system generates a three-dimensional coordinate system within the work cell. One of the light projector and the photogrammetry system identifies a location of the surface of the workpiece within the three-dimensional coordinates system. The controller calculates geometric location of the item on the surface of the work piece in the three-dimensional coordinate system as identified by the optical device. The controller signals the light projector to project a beam of light onto the surface of the workpiece identifying a disposition of the item disposed upon the surface of the workpiece.
