    • A stereoscopic image aligning apparatus (200) 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 (200) includes: an image pair obtaining unit (205) 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 (252) 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 (254) 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 (260) transforming the first image using the homography transformation matrix; and an output unit (210) outputting: a third image that is the transformed first image; and the second image.
    • 立体图像对准装置(200)以比常规装置更短的时间自动对准用于立体观看的图像对,其可应用于由单个传感器相机或可变基线相机捕获的图像对,而不依赖于相机参数。 立体图像对准装置(200)包括:图像对获取单元(205),获得包括与左眼图像相对应的左眼图像和右眼图像的图像对; 对应点检测单元(252),检测表示包括在作为图像对的图像之一的第一图像中的第一点的集合的对应点和包括在作为另一个图像的第二图像中的第二点 的图像对并对应于第一点; 第一矩阵计算单元(254)计算用于变换第一点的单应变换矩阵,使得第一和第二点之间的垂直视差最小并且满足对极约束; 变换单元(260),其使用所述单应变换矩阵来变换所述第一图像; 以及输出单元(210),输出:作为变换后的第一图像的第三图像; 和第二个图像。
