ABSTRACT:
An information processing device for obtaining placement information regarding an imaging device of markers to be calibrated that are provided upon the imaging device, includes: a first image obtaining unit adapted to obtain a first image photographed with the imaging device; a second image obtaining unit adapted to obtain a second image obtained by photographing the imaging device from a bird's-eye view position; a first detecting unit adapted to detect information relating to image coordinates of reference markers placed in a scene, from the first image; a second detecting unit adapted to detect information relating to image coordinates of markers to be calibrated from the second image; and a calibration information calculating unit adapted to obtain the calibration information using information relating to image coordinates of the reference markers detected by the first detecting unit and the second detecting unit.
