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 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: A triangulation-type, three-dimensional imager device uses photogrammetry to provide alignment or registration of the multiple point clouds of an object generated by the imager. The imager does not need a calibrated artifact such as a scale bar in its use of the photogrammetry process but instead uses the point cloud data generated by the imager to set the scale required by and utilized in the photogrammetry process.
