Help with QR Code

[Pedroski55]

The QR codes I made were made with the module qrcode.

They are .png images

To read the info contained, you can use cv2 (which gives computers eyes!):

import cv2
from pyzbar import pyzbar as pzb

qr = '/home/pedro/summer2023/OMR/21BE/21BE_QRcodes/21BE1/2125010102_曹宇_QR.png'

image = cv2.imread(qr)
decodedObjects = pzb.decode(image)
for obj in decodedObjects:
    print("Type:", obj.type)    
    print("Data: ", obj.data, "\n")
    # this is the content of the QR code as a string
    string=obj.data.decode('utf-8')
    print(f'The information in this QR code is: {string}')
