Abstract: A 3D shape restoration method and a device of an object using multi-viewpoint image information are provided to obtain a realistic image by rendering restored results, thereby showing an excellent restoration quality for 3D shape restoration of a dynamic object. A silhouette and color extractor(104) inputs multi-viewpoint images for taking pictures of an object at various viewpoints. The silhouette and color extractor extracts silhouette information and color information. A visual hull restorer(106) configures a visual hull through silhouette intersection. A polygon approximation unit(108) moves along with a section of the visual hull. The polygon approximation unit approximates a sectional polygon to a geometric external form of the object by using the color information. A mesh structure generator(110) connects the approximated polygon in mesh structure. The mesh structure generator expresses a 3D geometric external form of the object.
