20140253719 | GALVANOMETER SCANNED CAMERA WITH VARIABLE FOCUS AND METHOD - 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 minor 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. | 09-11-2014 |
20140210996 | LASER PROJECTION SYSTEM WITH MOTION COMPENSATION AND METHOD - 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. | 07-31-2014 |
20130253682 | LASER PROJECTION SYSTEM USING VARIABLE PART ALIGNMENT - A method of projecting a template on a workpiece provides a measurement system for determining a location of a workpiece and a laser projector for projecting a laser template. A feature on the workpiece having geometric significance is identified. A physical location of the feature in a three dimensional coordinate system is determined and compared to a theoretical location of the feature on computer model of the workpiece. A template correlated to the feature is selected. The projection of the template onto the workpiece relative to the feature is optimized by correlating alignment of the physical location of the feature with the computer model of the feature. The template is projected onto the workpiece based upon the optimized projection for directing work to be performed on the workpiece. | 09-26-2013 |
20130250094 | LASER PROJECTION SYSTEM AND METHOD - 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. | 09-26-2013 |
20080249649 | LASER PROJECTOR CONTROL SYSTEM - A laser projector system includes a computer and a laser projector for projecting a laser image on a target surface, particularly in a factory or manufacturing environment. The computer is disposed remote from the laser project and provides the laser projector with a command and control signal. Communication between the computer and the laser projector is accomplished with power line network adapters. These adapters modulate an AC waveform to encode the command and control signal and other data. Thus, communication between the computer and the laser projector is accomplished without need for long runs of communication cables. | 10-09-2008 |
