Abstract:
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 local tag data contained in the imaged portion; and (c) determining a position of the reader. The imaged portion has a diameter of at least one tag diameter and less than two tag diameters.
