Can not decode qrcode in binary

[cosing]

Expected behaviour

qrCodeDetector.detectAndDecode()[0] should be bytes.

same issue:https://stackoverflow.com/questions/77150620/opencv-is-there-a-way-to-decode-qrcode-in-binary-rather-than-string

Actual behaviour

use qr_output.py

import qrcode

qr = qrcode.QRCode(
    version=9,
    error_correction=qrcode.constants.ERROR_CORRECT_L,  # 最低纠错级别，存储最大数据量
)

binary_data = b'\x30' * 230  # 256 字节的序列重复 11 次，总共 2,816 字节
binary_data = bytes(range(127, -1, -1))+bytes(range(128, 256, 1))
print(binary_data)
qr.add_data(qrcode.util.QRData(binary_data, mode=1 << 2))

qr.make(fit=True)

img = qr.make_image(fill_color="black", back_color="white")
img.save("output_qr.png")

then use qr_input

from PIL import Image, ImageDraw, ImageFont
from pyzbar.pyzbar import decode, Decoded, Rect

def get_qr(image: Image.Image) -> Decoded:
    result = decode(image)
    if len(result) != 1:
        print("multy qr code")
    result = result[0]
    return result

qrcode_filename = r"output_qr.png"

ori_image = Image.open(qrcode_filename)
qr_info = get_qr(ori_image)
print(qr_info)

import cv2

print(cv2.__version__)
qrcode_image = cv2.imread(qrcode_filename)
qrCodeDetector = cv2.QRCodeDetector()
a = qrCodeDetector.detectAndDecode(qrcode_image)

print(type(a[0]))

out:

  • x86
• opencv-python version
  • 4.7.0

Issue submission checklist

• This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
• I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
• The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
• I'm using the latest version of opencv-python
