Abstract: A system and method for coordinate measurement is provided. The system includes a laser tracker and a moveable articulated-arm coordinate measuring machine (AACMM). The AACMM has an articulated arm with a probe end and an actuator. A retroreflector is coupled to the probe end. When the AACMM is in a first position, the system emits a laser beam and measures a position of the retroreflector while the AACMM also measures the position of retroreflector. When the AACMM is in a second position, and based on an activation of the at least one actuator by an operator, the system transmits a signal from the AACMM to the laser tracker and rotates the laser tracker towards the second position in response to the laser tracker receiving the signal. A means for transforming the first or second coordinate system to a common coordinate frame of reference is provided.

Abstract: An assembly that includes a projector and camera is used with a processor to determine three-dimensional (3D) coordinates of an object surface. The processor fits collected 3D coordinates to a mathematical representation provided for a shape of a surface feature. The processor fits the measured 3D coordinates to the shape and, if the goodness of fit is not acceptable, selects and performs at least one of: changing a pose of the assembly, changing an illumination level of the light source, changing a pattern of the transmitted With the changes in place, another scan is made to obtain 3D coordinates.

Abstract: A noncontact optical three-dimensional measuring device that includes a projector, a first camera, and a second camera; a processor electrically coupled to the projector, the first camera and the second camera; and computer readable media which, when executed by the processor, causes the first digital signal to be collected at a first time and the second digital signal to be collected at a second time different than the first time and determines three-dimensional coordinates of a first point on the surface based at least in part on the first digital signal and the first distance and determines three-dimensional coordinates of a second point on the surface based at least in part on the second digital signal and the second distance.
