Methods and systems are provided for generating a digital model of at least a part of an object referenced to a global coordinate system. An initial digital model, referenced to a local coordinate system associated with the optical device and representative of the respective part, is provided using an optical device at a relative location with respect to the object. The optical device has a plurality of visually exposed optical markers, at known locations with respect to the optical device and referenced to a marker coordinate system. The location of the optical device with respect to an external camera arrangement is determined, based on relating the relative locations of the markers with respect to one another, as they appear from a viewpoint of the external camera arrangement, to their relative locations as referenced to the marker coordinate system. The camera viewpoint is at a known location referenced to the global coordinate system. A transformed digital model is generated, representative of the respective part and referenced to the global coordinate system, based on modifying the initial digital model according to the location of the optical device. |
