placing said feature mapped model into an imaging plane of one of said at least one real world image;

comparing said feature mapped model of said structure that is placed into the imaging plane of said at least one real world image with said one of said at least one real world image; and

based on said comparing, determining the accuracy of said one or more three-dimensional models of said structure, wherein a score is associated with said one or more three-dimensional models.
