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 1):
A method for correcting an image of a multi-camera system by using a multi-sphere calibration apparatus, in which a multi-sphere calibration apparatus with at least two spheres vertically arranged on a support at predetermined intervals and a calibration unit are used, the method comprising:\n (a) calibration parameter acquisition for determining by the calibration unit a calibration parameter value for a geometric error of each camera by using the multi-sphere calibration apparatus; and (b) image calibration for correcting and outputting an image obtained by photographing an actual subject by the calibration unit by using the calibration parameter acquired in the step (a).
