Carved Visual Hull using Correlation of Projected Pixels
Woo-Seok Jang, Yo‐Sung Ho · ICEIC : International Conference on Electronics, Informations and Communications · 2010
In this paper, we propose a 3-D object reconstruction method. First, Initial silhouette of a 3-D object is generated by a shape from silhouette technique, it is carved to represent details of the 3-D object using color consistency. A surface point of the 3-D object obtained by visibility information is projected on the 2-D image during carving process. We select the projection samples using correlation of all pixels in projected region. These samples are considered to form the shape of the 3-D object. We obtain more reasonable threshold value of object carving through this process. Thus, it provides a efficient 3-D object carving process. After mapping proper color values to the surface points of the 3-D object for the more realistic 3-D model, it generates a good result of 3-D object reconstruction.
