Github uses QRCodeGenerator to generate QR and transform a new code

Github search QRCodeGennerator, first go to

the new code image generated by the software interface , the role of this code is to use aruco to locate, and then use zbar to identify the QR code, together with identification and 3D positioning, first upload the image, then add the code
code modification
