1. A method of aligning a position of a camera in a multi-camera system photographing multi-images, the method comprising: defining a correspondence relation between images photographed in the multi-camera system; estimating an initial position of the camera using the correspondence relation between the images and a Structure From Motion (SFM) algorithm; redefining a changed correspondence relation between the images as a result of the estimation of the initial position of the camera using a bundle edge to generate an optimal edge; and correcting the position of the camera based on the optimal edge.
