Multiview image calibration and rectification for an effective 3D display

In this paper, multiview calibration system for an effective 3D display is proposed. This calibration system can obtain non-calibrated 4-view image from multiview camera calibration system. Also it can be rectify camera's lens distortion, an error of brightness and color, and distortion of geometry. In this paper, the miss-matching of the brightness and the colors are calibrated by extracting the feature point and correspondence point. In addition, the difference of brightness is calibrated by using the differential map of brightness from each camera's image. A spherical lens distortion is corrected by extracting the pattern of the multiview camera images. Finally the camera error and size among the multiview cameras is calibrated by removing the distortion which is removing error components caused by the housing, the location of censor, and the distortion of lenses. Accordingly, this proposed multiview camera calibration system enables to effect mutiview 3D display and acquire realistic 3D image.
