1. A method for creating a 3-D curved surface by using corresponding curves in a plurality of images, the method comprising: (a) performing an NURBS (non-uniform rational b-splines) fitting curve with respect to one image in a plurality of images having camera calibration by capturing the same subject in respectively different positions, and simultaneously using control points designated in a curve characterizing a subject shape; (b) performing a fitting curve with respect to subjects of the images except for the one image by using the control points and a camera calibration information of a corresponding image; and (c) creating a curved surface by designating a 3-D curve created in the subject of each of the images.
