Paper Abstract

An approach obtaining three dimensional object shapes from a series of silhouette images is presented. A two dimensional image sequence of an object put on a turning table is taken by a video camera at regular time intervals to obtain silhouette images from multiple viewpoints. A pillar is obtained by sweeping the silhouette along a line parallel to the viewing direction. An intersection of the pillars from all the viewpoints surrounding the object is sampled to give a set of volume data. The segmentation and the modeling of potted plants are also studied as an application of computer graphics. The set of volume data is segmented into three parts of a potted plant, i.e., a pot, stems and leaves. Then, the pot and the stems are modeled by frustums and each of the leaves is approximated by two Bezier surface patches.
