As a kind of widely used form of two-dimension
codes, the QR codes have been widely applied in various
aspects of our life, but in the process of the use of the QR
codes, the QR code images captured often suffer from
deformity because the QR code label is attached onto the
object irregular surface (for example, a curve surface) or the
camera and the QR code label are different in position;
therefore, the QR code image recognition correction method
based on the shape function has been put forward and
verified, with the experimental results showing that the
improved algorithm can restore the graphic effect. |
