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

    摘要: An ambient illumination shielding apparatus for an imaging-based scanner adapted to read direct part marking (DPM) bar codes. The shielding apparatus includes an illumination shield extending from a housing of the scanner and extending along at least a portion of a path of travel of an aiming pattern generated by an aiming apparatus of the scanner. The shield passes illumination within a predetermined wavelength range and impedes passage of illumination outside of the predetermined wavelength range. The predetermined wavelength range of the shield includes a wavelength range of the aiming pattern generated by the aiming apparatus. The shielding apparatus further includes a filter disposed in proximity to an imaging system of the scanner and passing illumination within a predetermined wavelength range to the pixel array and impeding the passage of illumination outside of the predetermined wavelength range. The predetermined wavelength range of the filter includes a wavelength range of an illumination system of the scanner.

    摘要: Interleaving multiple logical data streams into one physical data stream reduces overhead required to process the multiple logical data streams. Multiple arrays of data values are interleaved into a combined array of data that simulates a frame of data for input to a data port such as a video port. Revised timing and synchronization signals are provided to permit transmission of the combined array according to video data port protocol. The processor includes instructions for locating the various arrays of data values within the combined array.

    摘要: A two dimensional symbol is decoded by forming a binary image that includes the symbol. The binary is used to generate symbol margins for use in digitization. By using the binary image to determine the symbol margins, margins can be located efficiently and in the presence of symbol contrast variation caused by irregularities in the marked surface or light source angles. Digitization proceeds based on the determined margins.
