Abstract
A system of camera calibration includes at least one first equipment and at least one second equipment, wherein a camera of at least one camera includes at least two image capturing groups, each image capturing group of the at least two image capturing groups includes at least two image capturers. Each first equipment provides at least one first calibration pattern, and the at least one first calibration pattern is utilized to calibrate first images including the at least one first calibration pattern captured by a plurality of corresponding image capturers of the at least two image capturing groups. Each second equipment provides at least one second calibration pattern, and the at least one second calibration pattern is utilized to calibrate second images including the at least one second calibration pattern captured by two corresponding adjacent image capturers of the at least two image capturing groups.
