ABSTRACT:
A substrate having a coding pattern disposed on a surface thereof. The coding pattern comprises a plurality of target elements defining a target grid. The target grid comprises a plurality of cells, wherein neighboring cells share target elements. A plurality of data elements are contained in each cell. Tags are defined by a plurality of contiguous cells and each tag comprises respective tag data encoded by a respective set of the data elements. Each cell comprises an orientation symbol encoded by at least one data element. Any tag-sized portion of the coding pattern is guaranteed to contain a plurality of the orientation symbols. Each orientation symbol identifies an orientation of a layout of the tag data with respect to the target grid, enabling a relative orientation of an optical reader imaging the coding pattern to be determined.
