A 3D coordinate measuring system includes a six-DOF unit having a unit frame of reference and including a structure, a retroreflector, a triangulation scanner, and an augmented reality (AR) color camera. The retroreflector, scanner and AR camera are attached to the structure. The scanner includes a first camera configured to form a first image of the pattern of light projected onto the object by a projector. The first camera and projector configured to cooperate to determine first 3D coordinates of a point on the object in the unit frame of reference, the determination based at least in part on the projected pattern of light and the first image. The system also includes a coordinate measuring device having a device frame of reference and configured to measure a pose of the retroreflector in the device frame of reference, the measured pose including measurements of six degrees-of-freedom of the retroreflector. |

1. A three-dimensional (3D) coordinate measuring system including:
a six degree-of-freedom (six-DOF) unit having a unit frame of reference, the unit including a structure, a retroreflector, a triangulation scanner, and an augmented reality (AR) camera, the retroreflector, the triangulation scanner, and the AR camera attached to the structure, the triangulation scanner including a first camera and a projector, the projector configured to project a pattern of light onto an object, the first camera configured to form a first image of the pattern of light on the object, the projector and the first camera configured to cooperate to determine first 3D coordinates of a point on the object in the unit frame of reference, the determination based at least in part on the projected pattern of light and the first image, the AR camera being a color camera configured to obtain a color image in the unit frame of reference; and a coordinate measuring device having a device frame of reference, the device configured to measure a pose of the retroreflector in the device frame of reference, wherein the measured pose includes measurements of six degrees-of-freedom of the retroreflector. |
