360-DEGREE IMAGE PHOTOGRAPHING DEVICE

PROBLEM TO BE SOLVED: To enable acquisition of an image of a real object that is seen from 360-degree directions without performing troublesome work on image processing. SOLUTION: A computer connected to a turntable on which a plurality of photographing devices and photographic subjects are installed, is equipped with: a rotation controller which rotates the turntable based on an input angle of rotation; a photographic section which takes a photograph whenever the turntable rotates and acquires the image of the photographic subjects from a plurality of photographing devices; a coordinate system setting section which sets up a coordinate system based on positions of feature points of extracted photographic subjects; a viewpoint parameter computing section which computes viewpoint parameters including position data which indicates position coordinates of the photographing device and direction data which indicates the direction to which the photographing device is facing based on the camera parameters including the coordinate system set up by the coordinate system setting section and the focus distance and the installed position of the photographing device; and a corresponding data storage section which associates and stores the image acquired by the photographic section and the viewpoint parameter computed by the viewpoint parameter computing section.
