Abstract
A three-dimensional (3D) measuring system and a method of determining a distance is provided. A three-dimensional (3D) measuring system includes a master part having a first base part and a first part-under-test including a second base. A photogrammetry camera images the master part to generate two-dimensional (2D) images. A first 3D imager determines 3D coordinates in a first imager frame of reference. A second 3D imager determines 3D coordinates in a second imager frame of reference. The system determines in a system frame of reference a first pose of the first imager and a second pose of the second imager. The system is further configured to determine 3D coordinates of the first part-under-test in the system frame of reference.
