ALIGNING A LOCALLY-RECONSTRUCTED THREE-DIMENSIONAL OBJECT TOA GLOBAL COORDINATE SYSTEM

A system and method are described for aligning a locally-reconstructed three - dimensional object, whose local reconstruction is relative to a local coordinate system (14), to a global coordinate system by using pre-mapped control points which are projected onto one or more of the images that may b e used to generate the local reconstruction. A system includes a control point information generator and an alignment generator (17). The control point information generator is configured to identify in at least image associated with a local reconstruction of the object a projected of at least one contro l point in the scene onto the at least one image (20), and generate local projected coordinate information indicating coordinated of the projection in the at least one image.
