PROBLEM TO BE SOLVED: To provide a technique which can raise the calibration precision of an imaging device in a short time.SOLUTION: The calibration device comprises: a similarity calculating part which, for each of a plurality of the captured images obtained by the imaging device which captures the calibration board having a feature point, calculates the similarity to each of a plurality of master images on which the calibration board is captured at mutually different positions; a classifying part which classifies a plurality of the captured images into a plurality of groups based on the similarity; a calibration processing part which, based on the representation image group in which the similarity extracted from a plurality of groups is beyond a predetermined value, determines a correction value to convert the physical position in the calibration board of the feature point and the position on the captured image; a deciding part which decides whether a conversion error due to the correction value is below a predetermined value; and a display part which displays information associated with the imaging number when the error is larger than a predetermined value. |
