Abstract
A reception unit 26a receives a still image of a spherical object captured by a camera 52 and information on the angle of view or the focal length of the camera 52 having captured the object, transmitted from a terminal (e.g., mobile communication terminal 50) including the camera 52. A calculation unit 28a calculates coordinates of four corners of a rectangle 210 enclosing the object from the still image of the object received by the reception unit 26a, and calculates direction vectors extending toward the object from the focal point of the lens of the camera 52, from the calculated coordinates of the four corners of the rectangle 210 enclosing the object and the angle of view or the focal length of the camera 52. An estimation unit 30a estimates three-dimensional coordinates of the center of the object, based on the direction vectors calculated by the calculation unit 28a.
