调用微信开源库进行二维码的检测和识别

import cv2 import numpy as np

cap = cv2.VideoCapture(0)

while True:

ret, frame = cap.read()

detector = cv2.wechat_qrcode_WeChatQRCode(“detect.prototxt”, “detect.caffemodel”,                  “sr.prototxt”, “sr.caffemodel”)

res, points = detector.detectAndDecode(frame)

for one_pt in points:

one_pt = np.array(one_pt, dtype=np.int)

cv2.polylines(frame, [one_pt], isClosed=True, color=(255, 0, 0), thickness=3)

print(‘条码信息:’, res)

cv2.imshow(“cap”, frame)

if cv2.waitKey(100) & 0xff == ord(‘q’):

break

cap.release()

cv2.destroyAllWindows()

汉字 字母均可识别生成     opencv的zbar库只能识别生成字母   如果二维码封存的是汉字 则zbar会乱码
