A gyro sensor section (34) measures the attitude of a camera (30) and a PC (10) performs required image processing and calculation of the position of a camera (30). The contour of an object is determined from a viewpoint where the camera can image the object freely by varying the position/attitude of the camera freely. A plurality of images and attitudes are obtained by capturing the object from a plurality of positions/attitudes and the position of the camera is determined using the contour of the object on the image. A three- dimensional shape is reconstituted from the position of the camera and the contour of the object.

Une section de gyrocapteur (34) mesure l'attitude d'une caméra (30) et un ordinateur personnel (10) effectue le traitement d'images requis et le calcul de la position d'une caméra (30). Le contour d'un objet est déterminé à partir du point de vue où la caméra peut produire librement une image de l'objet au moyen de la variation libre de position/attitude de la caméra. Une pluralité d'images et d'attitudes sont obtenues par saisie de l'objet à partir d'une pluralité de positions/attitudes et la position de la caméra est déterminée à l'aide du contour de l'objet sur l'image. Une forme tridimensionnelle est reconstituée à partir de la position de la caméra et du contour de l'objet.
