Claim One:
1. A method for measuring three-dimensional (3D) coordinates comprising: providing a dimensional measuring device having a triangulation scanner coupled to the body, the triangulation scanner having an operably coupled camera, the dimensional measuring device having a device frame of reference; in a first instance: determining with a six degree-of-freedom (six-DOF) tracking system a first position and a first orientation of the dimensional measuring device, the six-DOF tracking system being separate from the dimensional measuring device, the six-DOF tracking system having a system frame of reference; and determining, with the triangulation scanner, in the device frame of reference first 3D coordinates of a first 3D-coordinates point on the object; in a second instance: determining with the six-DOF tracking system a second position and a second orientation of the dimensional measuring device; capturing with the camera a second overview image of a second portion of the object and in response determining second 2D coordinates of a first cardinal point in the second overview image; and determining, with the triangulation scanner, in the device frame of reference second 3D coordinates of a second 3D-coordinates point on the object; in a third instance: positioning the dimensional measuring device in a location so as to be not measurable by the six-DOF tracking system; capturing with the camera a third overview image of a third portion of the object and in response determining third 2D coordinates of the first cardinal point in the third overview image and third 2D coordinates of a second cardinal point in the third overview image; and determining, with the triangulation scanner, in the device frame of reference third 3D coordinates of a third 3D-coordinates point on the object; determining in the system frame of reference first system 3D coordinates of the first 3D-coordinates point, second system 3D coordinates of the second 3D-coordinates point and third system 3D coordinates of the third 3D-coordinates point, the determining based at least in part on the second 2D coordinates of the first cardinal point, the third 2D coordinates of the first cardinal point, and the third 2D coordinates of the second cardinal point; and storing the first system 3D coordinates of the first 3D-coordinates point, the second system 3D coordinates of the second 3D-coordinates point, and the third systems 3D coordinates of the third 3D-coordinates point.
