Title: METHOD FOR CORRECTING IMAGE OF MULTI-CAMERA SYSTEM BY USING MULTI-SPHERE CORRECTION DEVICE
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 enable a more accurate image to be photographed since a geometric error of each camera is corrected.
