mac M2 python 逆向解析二维码

首先使用大家推荐的 zbar

• mac m2 python 3.8 安装无法解析动态库

安装

arch -arm64 brew install zbar 

python 使用

from pyzbar.pyzbar import decode
from PIL import Image

if __name__ == '__main__':

    file = 'qrcode_prod/492C230613047659_XCXM015492.png'
    img_pil = Image.open(file)
    res = decode(img_pil)
    print(res)

报错如下

  File "/Users/jimogangdan/PycharmProjects/pythonProject/venv/lib/python3.8/site-packages/pyzbar/pyzbar.py", line 7, in <module>
    from .wrapper import (
  File "/Users/jimogangdan/PycharmProjects/pythonProject/venv/lib/python3.8/site-packages/pyzbar/wrapper.py", line 151, in <module>

    libzbar, dependencies = zbar_library.load()
  File "/Users/jimogangdan/PycharmProjects/pythonProject/venv/lib/python3.8/site-packages/pyzbar/zbar_library.py", line 65, in load

ImportError: Unable to find zbar shared library

• 大意找不到共享库
• github stackoverflow 方案如下 然并卵 不好用

mkdir ~/lib
$ ln -s $(brew --prefix zbar)/lib/libzbar.dylib ~/lib/libzbar.dylib

很多方案失败

• dbr 需要liences
• openmv sensor 需要摄像头识别

终极不要钱的方案 zxingcpp

• 不需要拓展

pip install zxing-cpp

python 代码

img_mpl = plt.imread(file)
    np_arr = numpy.array(img_mpl).astype(np.uint8)
    results = zxingcpp.read_barcodes(np_arr)
    for r in results:
       print(f"Text:          '{r.text}'")
    print(f"Symbology:     {r.format.name}")
    print(f"Content Type:  {r.content_type.name}")
    print(f"Bounding Box:  {r.position}")
    print(f"Rotation:      {r.orientation}deg")
    print("---")
