我写了一个代码来读取USB网络摄像头和PYQT5中的一个应用程序的条形码，但我不知道如何将一个值从读取的条形码传递到我的应用程序主面板中的序列号窗口。
谁能给点建议吗？
相机自动检测条形码并在控制台中打印：

import cv2
import numpy as np
from pyzbar.pyzbar import decode
import time

def decoder(image):
    gray_img = cv2.cvtColor(image,0)
    barcode = decode(gray_img)

    for obj in barcode:
        points = obj.polygon
        (x,y,w,h) = obj.rect
        pts = np.array(points, np.int32)
        pts = pts.reshape((-1, 1, 2))
        cv2.polylines(image, [pts], True, (0, 255, 0), 3)

        barcodeData = obj.data.decode("utf-8")
        barcodeType = obj.type
        string = "Data " + str(barcodeData) + " | Type " + str(barcodeType)
        
        cv2.putText(frame, string, (x,y), cv2.FONT_HERSHEY_SIMPLEX,0.8,(25,20,300), 2)
        if barcodeData not in used_codes:
                print("Barcode: "+barcodeData)
                used_codes.append(barcodeData)
                time.sleep(3)
        else:
                print('This code was aqlready used')
                time.sleep(3)

cap = cv2.VideoCapture(0,cv2.CAP_DSHOW)
used_codes = []
img_counter = 0

while True:
    ret, frame = cap.read()
    decoder(frame)
    cv2.imshow('Image', frame)
    code = cv2.waitKey(10)
    if code == ord('q'):
        break
    elif code == ord(' '):
        # SPACE pressed
        img_name = "opencv_frame_{}.png".format(img_counter)
        cv2.imwrite(img_name, frame)
        print("{} written!".format(img_name))
        img_counter += 1
