Abstract
A method for reconstructing a three-dimensional structure using silhouette information on a two-dimensional plane is provided. The method includes: obtaining silhouette images; creating a cube on a three-dimensional space using the silhouette images; calculating vertex coordinates on a two-dimensional image plane by projecting eight vertices of the three-dimensional cube on a two-dimensional image plane of a first camera; dividing into multiple inner voxels by dividing sides formed by the eight vertices by a divider; dividing into a predetermined number of regions by dividing sides connecting the coordinates by a predetermined divider; assigning indices by matching cubes of the three-dimensional cube to square regions on the two-dimensional image plane in one to one manner; storing indices of regions where the square regions meets with a first silhouette image; and reconstructing three-dimensional structure by finding common indices through repeatedly performing the steps using other silhouette images.
