Abstract:
A method for correcting an image of a multi-camera system by using a multi-sphere correction device is disclosed. According to the present invention, the method for correcting an image of a multi-camera system by using a correction unit and a multi-sphere correction device having two or more spheres, which are vertically arranged on a support at certain intervals, comprises: (a) a correction variable acquisition step of determining, by the correction unit, a correction variable value for a geometric error of each camera by using the multi-sphere correction device; and (b) an image correction step of correcting an image obtained by photographing an actual subject by using the correction variable acquired in step (a), and outputting the corrected image, thereby enabling a more accurate image to be captured since a geometric error of each camera is corrected.

Claim (Index 2):
The method of  claim 1 , wherein the step (a) includes:\n (a-1) disposition of at least two cameras on a circumference of a circle at predetermined angular intervals with same radius (R) based on a same center point; (a-2) disposition of the multi-sphere calibration apparatus at the center point; (a-3) setting of at least one of a zoom, an aperture, ISO, and resolution of the each camera such that a center of each camera image becomes a center of the multi-sphere calibration apparatus; (a-4) acquisition of an image of the multi-sphere calibration apparatus from the each camera by an image input unit of the calibration unit; and (a-5) determination and storage of the calibration parameter of each image by a controller of the calibration unit.
