Provided is a calibration apparatus that performs calibration by using a captured image of a chart 200 including a plurality of plane surfaces forming a predetermined angle θ. An imaging apparatus 12 simultaneously images chart patterns depicted on each of the plane surfaces of the chart 200. In this instance, the chart pattern depicted on each of the plane surfaces of the chart 200 is inversely projected in accordance with a distance from an imaging plane as indicated in (a) such that patterns in which feature points are uniformly distributed within the captured image are obtained as indicated in (b).
