Images of an object viewed from a plurality of points of view is input through an image inputting unit. Change of orientation of the image inputting means, occurring when the images of the object are input, is detected. Change of position of point of view, occurring when the images of the object are input, is detected. Characteristic points are extracted from the image which is input previously, each of the characteristic points corresponding to a respective one of objects points on the object. Corresponding points are extracted from the image which is input currently, each of the corresponding points corresponding to a respective one of the characteristic points. The three-dimensional position of each of the object points is calculated, based on the change of orientation and the change of position of point of view of the image inputting unit and the data of the characteristic points and the corresponding points.
