Abstract
Provided is a method for creating a 3-D curved surface by using corresponding curves in a plurality of images. The method includes performing an NURBS fitting curve with respect to one image in a plurality of images having camera calibration and extracted camera parameter by using control points designated in a curve characterizing a subject shape. When the curve fitting is performed with respect to the curve that commonly exists in more than two images, a 3-D curve is created by using a camera calibration information, or a 3-D curved surface is created by creating a plurality of 3-D curves or straight lines. Therefore, a 3-D curved surface model can be easily and quickly created by simplifying a complex modeling process for an actual object modeling into an actual image-based modeling process.
