Abstract

A region defined in relation to a surface, and a method for defining such a region; coded data being disposed within the region, the coded data being indicative of an identity of the region; in one embodiment, the coded data comprising a plurality of tags which substantially cover the region, the tags being usable to uniquely identify the region or at least distinguish it from other regions defined in relation to the surface.

Claims

1. A region defined in relation to a surface, coded data being disposed within the region, wherein the coded data comprises a plurality of parts, at least one of the parts of the coded data including both position data indicative of a position of the part relative to the region and identity data indicative of an identity of the region, wherein the coded data comprises a plurality of substantially undifferentiated marks positioned relative to a set of predetermined nominal mark position, and wherein each mark has a minimum radius and a maximum radius and wherein a length of the mark'"'"'s minimum radius is greater than 40% of a length of the mark'"'"'s maximum radius.

2. A region according to claim 1, wherein each mark represents one of a plurality of coded values.

3. A region according to claim 2, wherein the coded value represented by a mark is at least partially determined by the position of the mark relative to the set of predetermined nominal mark positions.

4. A region according to claim 1 wherein the predetermined nominal mark positions are arranged relative to a plurality of nominal lines.

5. A region according to claim 4 wherein at least one pair of the lines are spaced apart from one another by a distance of less than 100 millimeters.

6. A region according to claim 1, wherein the marks have centers and wherein the relative spacing of the centers of at least one pair of adjacent marks is less than 12 millimeters.

7. A region according to claim 1, wherein any 10 millimeter diameter subregion of the region includes sufficient coded data to identify the region.

8. A region according to claim 1, wherein the coded data is also indicative of a plurality of reference points of the region and wherein any 10 millimeter diameter subregion of the region includes sufficient information to identify at least one reference point of the region.

9. The surface, including a region according to any one of the preceding claims.

10. A method of producing a surface having a region, the method including the steps of:

(a) defining coded data as a plurality of substantially undifferentiated marks, wherein each mark has a minimum radius and a maximum radius and wherein a length of the mark'"'"'s minimum radius is greater than 40% of a length of the mark'"'"'s maximum radius, wherein the marks are positioned relative to a set of predetermined nominal mark positions, the coded data comprising a plurality of parts, at least one of the parts of the coded data including both position data indicative of a position of the part relative to the region and identity data indicative of a region identity associated with the region; and

(b) disposing the coded data within the region on the surface.

11. A method according to claim 10, wherein each mark represents one of a plurality of coded values.

12. A method according to claim 11, wherein the coded value represented by a mark is at least partially determined by the position of the mark relative to the set of predetermined nominal mark positions.

13. A method according to claim 10 wherein the predetermined nominal mark positions are arranged relative to a plurality of nominal lines.

14. A method according to claim 13 wherein at least one pair of the lines are spaced apart from one another by a distance of less than 100 millimeters.

15. A method according to claim 10, wherein the marks have centers and wherein the relative spacing of the centers of at least one pair of adjacent marks is less than 12 millimeters.

16. A method according to claim 10, wherein any 10 millimeter diameter subregion of the region includes sufficient coded data to identify the region.

17. A method according to claim 10, wherein the coded data is also indicative of a plurality of reference points of the region and wherein any 10 millimeter diameter subregion of the region includes sufficient information to identify at least one reference point of the region.
