METHOD OF IMAGING CODING PATTERN AND IDENTIFYING CELL TRANSLATIONS FROM DIFFERENT ORIENTATIONS

摘要

A method of imaging a coding pattern disposed on a surface of a substrate. The method comprises the steps of: (a) capturing an image of a portion of the coding pattern; (b) sampling a registration symbol contained in the imaged portion; (c) mapping a set of data elements to a first translation code symbol value when read in a first orientation or a second translation symbol code value when read in a second orientation; (d) determining a translation from the mapped set of data elements; and (e) using the translation to sample and decode tag data.
