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

摘要

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 be 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 control 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.
