METHOD, DEVICE, AND SYSTEM FOR GENERATING, REPAIRING, AND IDENTIFYING AN INCOMPLETE QR CODE

Abstract:

A method of reading a QR code is described. The method includes capturing an image of an incomplete QR code. The incomplete QR code has a missing region with a missing functional pattern. Further, the functional pattern is added to the missing region in the incomplete QR code to form a recovered QR code. Subsequently, pixels are added randomly to the missing region surrounding the functional pattern to add to the recovered QR code. The recovered QR code has a number of functional patterns and a number of modules. Further, data is read from the recovered QR code.
