Abstract
A reference sheet is employed on which reference points are arranged irregularly and asymmetrically. An object of interest is placed on the reference sheet. The object of interest is shot together with the reference points by a camera. A shooting position of the camera is calculated according to the Hough transform method on the basis of the position of a reference point in the obtained object image. A three-dimensional model is generated according to the obtained object image and shooting position. Therefore, a simple and economic three-dimensional modeling apparatus that does not require a turntable can be provided.
