Barcodes have gained widespread commercial adoption for representing alphanumeric data in a visual format on a surface. Barcodes store data in the widths and spacings of printed parallel lines. While barcodes work reliably, their utility is limited by the physical area needed to implement them and the type of information they can represent.
”2d ” codes, which represent data in two dimensions, have been developed to address the shortcomings of barcodes. These codes enable the representation of a larger amount of data in a smaller surface (that is, a much higher information density and the ability to be used on smaller form factors). In addition, 2d codes can be used to represent any predetermined shapes, not just alphanumeric information.
However, 2d code with an uncertain rotational angle (for example, mirrored or rotated) is susceptible to providing incorrect data unless the orientation can be properly determined.
The subject invention is a 2d coding system that uses alignment markers in order to discriminate the orientation of the image. The invention provides a compact and highly accurate labeling technique for determining orientation in a broad range of 2d coding systems. The invention relies on the use of three or more alignment markers to determine the orientation of the 2d array.
