CODING PATTERN WITH CELLS HAVING TRANSLATION DATA DEFINING A TRANSLATION OF THE CELL

摘要

A substrate having a coding pattern disposed on a surface thereof is disclosed. The coding pattern has target elements defining a target grid. The target grid has cells. A plurality of data elements are contained in each cell. Tags are defined by a plurality of contiguous cells and each tag has respective local tag data encoded by a respective set of the data elements. Each cell contains translation data encoded by a respective set of data elements. The translation data identifies a translation of the cell relative to the tag containing that cell.
