<P>PROBLEM TO BE SOLVED: To easily arrange a tile type sheet, where a plurality of tags are embedded, or to easily change the arrangement. <P>SOLUTION: A method for detecting the relative position of a mobile unit has processes of: assigning each inherent sheet number to a plurality of tile type sheets; setting a marker to a specific position; creating a tag position table for enabling the sheet number of the tile type sheet, where a tag ID and a tag are embedded, to correspond to the relative position for the marker, and a sheet position table for enabling the relative position of the marker of another tile type sheet for the marker of a reference tile type sheet to correspond to the sheet number; and detecting the sheet number of the tile type sheet from the tag ID and the relative position to the marker, and further detecting the relative position of the tag (mobile unit) for the marker of the reference tile type sheet from the relative position of the reference tile type sheet to the relative position with the marker of the tile type sheet. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
