Abstract: A camera assembly for generating a high resolution image of an area of interest on a workpiece includes a sensor array and an optical lens that focuses light reflected from the workpiece onto the sensor array. The sensor array is inclined relative to an optical axis defined by the optical lens disposed in a fixed position relative to the optical lens. A galvanometer driven mirror assembly directs a field of view of the optical lens toward the area of interest on the workpiece translating light reflected from the area of interest of the workpiece onto the sensor array. The inclination of the sensor array provides varying degrees of resolution relative to a distance of the workpiece area of interest from the camera assembly enabling the camera assembly to generate high resolution images at varying distances from the camera assembly without adjusting the optical lens relative to the sensor array.

Abstract: A laser projection system for projecting an image on a workpiece includes a photogrammetry assembly and a laser projector, each communicating with a computer. The photogrammetry assembly includes a first camera for scanning the workpiece, and the laser projector projects a laser image to arbitrary locations. Light is conveyed from the direction of the workpiece to the photogrammetry assembly. The photogrammetry assembly signals the coordinates light conveyed toward the photogrammetry assembly to the computer with the computer being programmable for determining a geometric location of the laser image. The computer establishes a geometric correlation between the photogrammetry assembly, the laser projector, and the workpiece for realigning the laser image to a corrected geometric location relative to the workpiece.

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 accurately projecting a laser image pattern on a work surface and continuously compensating for relative dynamic movement between the laser and the work surface, including establishing a position of the camera in three dimensions relative to the work surface by locating the targets in the camera image, establishing a position of the laser relative to the work surface utilizing the fixed position of the laser relative to the camera, and using a computer to continuously adjust the rotation of the laser projector mirrors in response to dynamic movement of the laser projector relative to the work surface as determined by the camera. In one embodiment, the computer continuously tracks at least two prior locations of the laser projector relative to the work surface and predicts the next location of the laser, compensating for movement of the laser relative to the work surface.

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.
