Each of the plurality of markers includes a reflective surface portion visible by the camera and a distinct identifiable portion visible by the 3D scanner system. The apparatus further involves a connector mechanism to connect the apparatus to a reference location. The apparatus is in a field of view of the 3D scanner system and the camera within a timeframe of the 3D scan.
