Surface Having Optically Readable Printed Tags |
摘要 |
A surface having an optically readable pattern of dots printed thereon. The pattern comprises an arbitrarily shaped constant background pattern of dots and/or blanks. The constant background pattern defines discrete areas of coded data represented by a plurality of dots positioned according to an encoding scheme. Each discrete area contains orientation information for enabling an optical reader to determine an orientation relative to the pattern of dots.
