Abstract
A technique is disclosed for easily performing calibration of a camera by using a MMS. A calibration device for a camera that is configured to photograph the sun includes an in-image sun position identifying unit 115, a sun position estimating unit 113, and a camera attitude calculating unit 116. The in-image sun position identifying unit 115 identifies a position of the sun in an image that is photographed by the camera. The sun position estimating unit 113 estimates a position of the sun in the image based on orbital information of the sun. The camera attitude calculating unit 116 calculates attitude of the camera based on differences between identified positions and the estimated positions of the sun in the images.
