PRODUCT HAVING ABSOLUTE POSITIONING CODE PATTERN ON A SURFACE THEREOF AND METHOD FOR GENERATING ABSOLUTE POSITIONING CODE PATTERN
摘要:
Disclosed is a product having an absolute positioning pattern on its surface and a method for forming the absolute pattern. The product includes first cells displaying coded binary data or displaying coded data expressed in terms of at least three digits; second cells displaying data coded in a manner different from the first cells or having no data; and a unit cell pattern formed by a group of at least a predetermined number of the first and second cells. The combination of data corresponding to the first cells within the unit cell pattern indicates an absolute coordinate of the corresponding unit cell pattern, and the unit cell pattern is differentiated from other adjacent unit cell patterns by the second cells within the unit cell pattern. The disclosed product and method require a smaller amount of operation to calculate the coordinate value compared with the prior art, but can display a broader position.
