OpenCV4新API：QRCode识别

import numpy as np

img = cv2.imread('/opt/develop/resources/images/1546100572.png')
img_gray = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)

transform = None
qrcode = cv2.QRCodeDetector()

for i in range(count_experiments):
    # 检测与识别
    result_detection,transform,straight_qrcode = qrcode.detectAndDecode(img_gray)
    
    if result_detection:
        print('result',result_detection)
        break
