Patent number: 11908162Abstract: A handheld three-dimensional (3D) measuring system operates in a target mode and a geometry mode. In the target mode, a target-mode projector projects a first line of light onto an object, and a first illuminator sends light to markers on or near the object. A first camera captures an image of the first line of light and the illuminated markers. In the geometry mode, a geometry-mode projector projects onto the object a first multiplicity of lines, which are captured by the first camera and a second camera. One or more processors determines 3D coordinates in the target mode and the geometry mode.Type: GrantFiled: December 20, 2021Date of Patent: February 20, 2024Assignee: FARO Technologies, Inc.Inventors: Francesco Bonarrigo, Paul C. Atwell, John Lucas Creachbaum, Nitesh Dhasmana, Fabiano Kovalski, Andrea Riccardi, William E. Schoenfeldt, Marco Torsello, Christopher Michael Wilson

Patent number: 10699442Abstract: A portable articulated arm coordinate measuring machine (AACMM) for measuring the coordinates of an object in space and a method of operating the AACMM is provided. The AACMM includes a laser line probe is having a projector and a camera, the projector projecting a line of light, the camera having a lens assembly and a sensor assembly. The sensor assembly having a filter disposed between a photosensitive array and the lens assembly. The filter has a plurality of red, green and blue pixels in a predetermined arrangement. A controller causes the camera to acquire a metrology image and a color image. 3D coordinates of points on a surface are determined based on the metrology image and a color is assigned to the points based on the color image. The exposure time for the color image is adjusted based on an Exposure To The Right or a Mid-gray color model.Type: GrantFiled: July 9, 2018Date of Patent: June 30, 2020Assignee: FARO TECHNOLOGIES, INC.Inventors: Jeremy W. Mares, Jacint R. Barba, Christopher M. Riehl, Christopher Michael Wilson, Keith G. Macfarlane, Kishore Lankalapalli, Paul C. Atwell, Michael Shen, Nitesh Dhasmana
