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: Techniques for localizing a portable articulated arm coordinate measuring machine (AACMM) are described. An example localization method includes in response to an AACMM base being placed at a first position, capturing a first set of images of a positioning element in a predetermined area. The method further includes determining first 3D coordinates of the positioning element using the first set of images. 3D coordinates corresponding to a position of a first measurement probe in the predetermined area are computed using the first 3D coordinates. Further, the method includes, in response to the base being moved to a second position, determining second 3D coordinates of the positioning element from the second position using a second set of images. Further, the localization method includes determining a translation matrix to convert the second 3D coordinates to the first 3D coordinates.

Abstract: A system and method of generating a two-dimensional (2D) image of an environment is provided. The system includes a housing having a body and a handle. A 2D scanner is disposed in the body and has a light source, an image sensor and a controller, the light source steers a beam of light within a first plane to illuminate object points in the environment. The image sensor is arranged to receive light reflected from the object points and the controller determines a distance value to at least one of the object points. An inertial measurement unit is provided having a 3D accelerometer and a 3D gyroscope. One or more processors are responsive to executable instructions for generating a 2D image of the environment in response to an activation signal from an operator and based at least in part on the distance values and the signal.
