1. A three-dimensional (3D) measuring system comprising:

  • a first set of 3D imagers, each designated by an index j between 1 and an integer N equal to or greater than 2, each 3D imager j configured to determine 3D coordinates of an object in an imager frame of reference, each 3D imager j having a 3D imager pose j within a system frame of reference, each 3D imager j including;

    a projector j configured to project a patterned light over an area onto the object;

    a camera j configured to capture an image of the patterned light on the object, the camera j including a lens j and a photosensitive array j, the camera j configured to image the patterned light on the object onto the photosensitive array j;

    a processor j mechanically coupled to the projector j and the camera j, the processor j configured to determine the 3D coordinates of the object in the imager frame of reference based at least in part on the projected patterned light, the image of the patterned light on the object captured by the camera j, and a relative pose of the projector j with respect to the camera j;

    a first mounting frame coupled to each 3D imager j in the first set of 3D imagers; and

    a system controller configured to obtain a system collection of 3D coordinates, the system collection of 3D coordinates being 3D coordinates of the object in the system frame of reference, the system collection of coordinates based at least in part on the determined 3D coordinates of the object provided by the first set of 3D imagers and on the 3D imager pose j in the system frame of reference of each 3D imager j in the first set of 3D imagers.
