Abstract
A first mirror and a second mirror are disposed in such a manner that their reflective surfaces are parallel and face toward each other. A mark is drawn between the first mirror and the second mirror. An image of the reflections of the mark in the first mirror and the second mirror is captured with a camera. Calibration of the camera system is performed based on the image.
