摘要: The disclosure relates to techniques for determining the presence, orientation and location of features in an image a two dimensional optical code. are adapted use mapping data pixel plane with grid locations grid-based code account size, rotation, tilt, warping distortion symbol. Where such is MaxiCode, disclosed presence MaxiCode bulls-eye, modules, primary modules secondary modules.
