Stereoscopic image aligning apparatus, stereoscopic image aligning method, and program of the same

Abstract

A stereoscopic image aligning apparatus () automatically aligns image pairs for stereoscopic viewing in a shorter amount of time than conventional apparatuses, which is applicable to image pairs captured by a single sensor camera or a variable baseline camera, without relying on camera parameters. The stereoscopic image aligning apparatus () includes: an image pair obtaining unit () obtaining an image pair including a left-eye image and a right-eye image corresponding to the left-eye image; a corresponding point detecting unit () detecting a corresponding point representing a set of a first point included in a first image that is one of the images of the image pair and a second point included in a second image that is the other of the images of the image pair and corresponding to the first point; a first matrix computing unit () computing a homography transformation matrix for transforming the first point such that a vertical parallax between the first and second points is smallest and an epipolar constraint is satisfied; a transforming unit () transforming the first image using the homography transformation matrix; and an output unit () outputting: a third image that is the transformed first image; and the second image.
