Abstract

A system is described for aligning a reconstructed three-dimensional object local coordinate system in a scene to a global coordinate system, comprising an image recording module and an image processor module (11 and 15). The image recording module is configured to (i) during a mapping phase, record at least one set of images from a respective location relative to a trial scene along with at least one marker, the set of images sufficient to allow a reconstruction of the at least one marker in a local coordinate system; and (ii) during an operational phase, record at least one set of images of a working scene from the respective location, the set of image being sufficient to allow a reconstruction of at least one portion of at one working object (11). The image processor module is configured to (i) during the mapping phase, reconstruct from the set of images recorded during the mapping phase the at least one marker in the local coordinate system and determine a relationship between the local coordinate system and the global coordinate system using information identifying the coordinate of the at least one marker in the global coordinate system; and (ii) during the operational phase, reconstruct from the set of images recorded during the mapping phase the at least one portion of the at least one working object in the local coordinate system determined during the operational phase, align the reconstructed at least one portion to the global coordinate system (15).
