POSITION-CODING PATTERN HAVING TAG COORDINATES ENCODED BY BIT-SHIFTED SUBSEQUENCES OF CYCLIC POSITION CODE

摘要

A substrate having a position-coding pattern disposed on a surface thereof. The position-coding pattern comprises a plurality of tags. Each tag encodes a w-bit subsequence of a cyclic code sequence. The w-bit subsequence maps to a corresponding coordinate codeword for the tag. Adjacent tags contain a w-bit subsequence shifted by one bit relative to each other in the cyclic code sequence.
