Calibration apparatus, calibration method, program for calibration, and calibration jig

摘要

A calibration apparatus which estimates a calibration parameter of an image acquisition apparatus (14), comprises a calibration jig (10) which includes at least two planes and in which calibration markers having known three-dimensional positions are arranged in each plane based on a predetermined rule. The calibration apparatus further comprises a calibration marker recognition section (12) configured to measure and number in-image positions of the calibration markers in at least one image obtained by photographing the calibration jig by the image acquisition apparatus, and a parameter estimate section (12) configured to estimate the calibration parameters of the image acquisition apparatus by the use of the three-dimensional position and the in-image position of the calibration markers numbered by the calibration marker recognition section.
