Abstract
Disclosed herein is a method for acquiring a three-dimensional (3D) image including: acquiring a 3D primary image of an object from two-dimensional (2D) primary image data acquired by first and second cameras when a predetermined pattern is projected on the object by a projector and a 2D primary image of the pattern-projected object is acquired by the first and second cameras, and then converting it into a 2D re-viewpoint image; correcting a missing area in the 2D re-viewpoint image corresponding to the 3D data missing area for compensating for a 3D data missing area caused by a curvature of the object and the points of view of the first and second cameras; and generating a corrected 3D image by referring to the 2D primary image data acquired by the first or second camera and the corrected 2D re-viewpoint image information.
