Cv2.imread() not always getting the data from qr codes

Python

Sorry but you have to insert os.path.isfile( savepathQRcodes + f ) in your loop :

for f in QRfiles:
    if os.path.isfile( savepathQRcodes + f ):
        img = cv2.imread(savepathQRcodes + f)
        if img is None:
            print("File exists but imread cannot read it : ", savepathQRcodes + f)
        else:
            detector = cv2.QRCodeDetector()
            data, bbox, straight_qrcode = detector.detectAndDecode(img)
            if data == '':
                count+=1
                missing.append(f)
                print("There is no data in file : ", savepathQRcodes + f)
            else :
                print(data)
    else:
        print("This file does not exist : ", savepathQRcodes + f)

What’s your platform and opencv version ?
