Abstract: A triangulation scanner having an enclosure, a projector coupled to the enclosure and configured to emit a first light, and three cameras also coupled to the enclosure. The scanner further includes at least one processor to determine the three-dimensional coordinates in a local frame of reference based at least in part on receiving the first light.

Abstract: A 3D sensor system with a mounting arrangement is provided. The system includes a 3D sensor that measures 3D coordinates of a surface, the 3D sensor having a body with a slot disposed in a side, the slot further having a recess centrally disposed thereon. One or more slot nuts are disposed in the slot. A mounting bracket is provided having a pair of keystone members and a dowel pin disposed therebetween, the keystone members being disposed in the slot and the dowel pin being disposed in the recess, the mounting bracket having a plurality of holes aligned with the slot. One or more fasteners are provided that extend through the plurality holes and engage the one or more slot nuts to couple the mounting bracket to the 3D sensor.

Abstract: A measurement system and a method of measuring an object is provided. The system includes a measurement platform having a planar surface. At least two optical sensors are coupled to the measurement platform that emit light in a plane and determines a distance to an object based on a reflection of the light. A linear rail is coupled to the measurement platform. A cooperative robot is coupled to move along the linear rail. A 3D measuring system is coupled to the end of the robot. A controller coupled to the at least two optical sensors, the robot, and the 3D measuring system, the controller changing the speed of the robot and the 3D measuring system to less than a threshold in response to a distance measured by at least one of the at least two optical sensors to a human operator being less than a first distance threshold.

Abstract: A method of determining a mathematical transformation to place three-dimensional (3D) coordinates of points measured by an articulated arm coordinate measurement machine (AACMM) and 3D points measured by a scanner in a common coordinate system is provided. The method including providing the 3D scanner and the AACMM having a probe. The scanner and AACMM each have a local frame of reference. Three non-collinear targets are measured with the probe and then with the scanner. 3D probe reference coordinates and 3D scanner reference coordinates are determined based on the measurement of the targets by the AACMM and scanner. The mathematical transformation is determined based at least in part on the 3D probe reference coordinates and the 3D scanner reference coordinates, the mathematical transformation characterized at least in part by a collection of parameters.
