Embodiment Construction

[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like parts throughout. Exemplary embodiments are described below with reference to the accompanying drawings.

[0027] FIG. 1A is a perspective view illustrating a photographing device 100 according to an exemplary embodiment. Examples of the photographing device 100 include a digital camera and other devices having a photographing function (such as a cellular phone). Therefore, exemplary embodiments may include any device that can perform a photographing operation. In an exemplary embodiment, a panoramic image is generated using a plurality of images (photographs) photographed by the photographing device 100 .

[0028] As shown in Figure 1A, the x, y, and z axes may be mutually orthogonal. However, the x, y and z axes may be arranged in different directions. In the structure shown in FIG. 1A, the z axis repr...

Abstract

Provided are an apparatus, method, and medium for generating a panoramic image. In the apparatus, a previously captured image and a currently captured image are projected onto a predetermined curved surface so as to form a first mapping image and a second mapping image, respectively. Movement values in predetermined directions are calculated for maximizing a color similarity between overlapped sections of the first and second mapping images. A panoramic image is generated using the first and second mapping images and the calculated movement values. Therefore, overlapped sections of neighboring images can be precisely superposed and aligned when a panoramic image is generated using a series of images.

Description

technical field [0001] Embodiments relate to an apparatus, method, and medium for generating a panoramic image, and more particularly, to an apparatus, method, and medium for generating a panoramic image by quickly and accurately stitching a series of images captured in various directions. Background technique [0002] A panoramic image is a series of images taken in different directions and stitched in a predetermined way. Panoramic images provide a wider field of view (FOV) of a scene than images captured in one direction. Thus, an extended view of the scene may be provided. [0003] Images with overlapping portions are captured to form a panoramic image. In detail, in a series of images taken for a panoramic image, the trailing edge of one image is ideally the same as the leading edge of the previous image. More realistic panoramas are obtained when images are stitched by precisely aligning overlapping portions of the images. [0004] A conventional panoramic image ge...
