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