PURPOSE: To accurately assign coordinates to images between a source position and a flat surface without using a device, which is heavy and fixed in terms of a cost, by determining the position of the source with respect to each image and the flat surface supporting the image with respect to an object. CONSTITUTION: The common parts of the respective image surfaces P11 and P12 and a reference surface PR are determined from the respective projections of markers A to C and O installed on a reference surface P onto each of the image surfaces P11 and P12 obtained from sources R1 and R2 by connecting points A to C, O and S to an object U. Next the respective positions between the source R1 and R2 concerning the reference surface PR and the image surface P11 and P12 from the respective projections of the marker S arranged outside the reference surface. Then, the coordinates of the group of mutually different straight lines contributing to the formation of the projections of the object U onto the respective image surfaces P11 and P12 is determined from information on this position. Thereby the coordinate of an image is easily added. |
