Method of Imaging a Coding Pattern and Determining Translation of Imaged Cells Relative to Tags

摘要

A method of imaging a coding pattern disposed on a surface of a substrate. The method comprises the steps of: (a) operatively positioning an optical reader relative to the surface and capturing an image of a portion of the coding pattern; (b) sampling and decoding one or more translation symbols contained in the imaged portion; (c) determining a translation of one or more cells of the coding pattern relative to a tag containing the cells; and (d) using the determined translation to sample and decode tag data contained in the imaged portion.
