Abstract
An information display member has an information display face of its known size. On the information display face, a first pattern is displayed to represent coordinate information indicative of a position of the displayed information display member. On the information display face, a second pattern is displayed to represent direction information indicative of an direction in which the information display face is oriented. The information display face of the information display member is image-acquired by means of a camera, and an image is acquired. A direction in which the camera is oriented is obtained by a length ratio of aspect on the information display face mapped on the image and the direction information displayed on the information display face. A distance between the camera and the information display face is obtained by a size of the information display face mapped on the image. The position coordinate of the camera is obtained from the direction in which the camera is oriented the distance and the coordinate information displayed on the information display face.
