Patent Images
1. A device for measuring three-dimensional (3D) coordinates of an object surface comprising:
- a processor; and
a triangulation scanner including a projector, a first scanner camera, a second scanner camera, and a scanner connector, the scanner connector configured to detachably couple to an arm connector of an articulated arm coordinate measurement machine (AACMM), the projector configured to project a scanner pattern onto the object surface, the projector having a projector perspective center and a projector optical axis, the first scanner camera configured to form a first image of the scanner pattern and to send a first electrical scanner signal to the processor in response, the first scanner camera having a first-camera perspective center and a first-camera optical axis, the second scanner camera configured to form a second image of the scanner pattern and to send a second electrical scanner signal to the processor in response, the second camera having a second-camera perspective center and a second-camera optical axis, the projector perspective center, the first-camera perspective center, and the second-camera perspective center being arranged in a triangular pattern on a first plane, the first plane not including the projector optical axis, the first-camera optical axis, or the second-camera optical axis,wherein the processor is configured to determine the 3D coordinates of the object surface whether the triangulation scanner is coupled to or uncoupled from the AACMM, the determining based at least in part on the scanner pattern, the first electrical scanner signal, and the second electrical scanner signal.
