Abstract

In a calibration device, entry work of coordinate information on a real space is not required. An imaging system is configured to include an image acquisition unit which acquires an image from an imaging device, an object extraction unit which extracts a plurality of objects from the image, a characteristic information addition unit which adds geometry information that indicates geometric relationships among the plurality of objects to each set of objects as characteristic information, a camera parameter estimation unit which obtains image coordinates of the objects in accordance with the characteristic information to estimate camera parameters based on the characteristic information and the image coordinates, and a camera parameter output unit which outputs the camera parameters.
