问题描述

我有数百张带有qr代码的图片(有时在一页上有0,1,2或更多qr代码......但它们总是在一行中)。我想



我想要的订单是:url1,url2,url3,url4,url5,url6 。

解决方案

我正在使用Windows,现在无法在linux上进行测试,但这似乎按预期工作。

  import sys,os 
try:
来自pyzbar.pyzbar import decode,ZBarSymbol
除外:
cmd =('py -m pip installpyzbar')
os.system(cmd)
from pyzbar.pyzbar import decode,ZBarSymbol

try :
来自PIL导入图片
除了:
cmd =('py -m pip installPillow')
os.system(cmd)
来自PIL导入Image

decoding = decode(Image.open(C:/ Temp / 13AZQ .png),symbols = [ZBarSymbol.QRCODE])
qr_dic = {}
for qr in decoding:
x = qr [2] [0] #Q2码的左侧位置
qr_dic [x] = qr [0]#存储在QR码中的数据

for qr in sorted(qr_dic.keys()):
print(qr_dic [qr] ])

输出:

  b'url1'
b'url2'
b'url3'
b'url4'
b'url5'


I have hundreds of pictures with qr codes (sometimes there are 0, 1, 2 or more qr codes on one page...but they are always in one line). I want to decode the qr codes from left to right. My idea is to split the qr codes in separate images.

Does somebody know a Linux (or Python) solution for this problem?

The order I want is: url1, url2, url3, url4, url5, url6.

解决方案

I'm on windows, no way of testing on linux right now, but this appears to work as expected.

import sys, os
try:
    from pyzbar.pyzbar import decode, ZBarSymbol
except:
    cmd = ('py -m pip install "pyzbar"')
    os.system(cmd)
    from pyzbar.pyzbar import decode, ZBarSymbol

try:
    from PIL import Image
except:
    cmd = ('py -m pip install "Pillow"')
    os.system(cmd)
    from PIL import Image

decoded = decode(Image.open("C:/Temp/13AZQ.png"), symbols=[ZBarSymbol.QRCODE])
qr_dic = {}
for qr in decoded:
    x = qr[2][0] # The Left position of the QR code
    qr_dic[x] = qr[0] # The Data stored in the QR code

for qr in sorted(qr_dic.keys()):
    print(qr_dic[qr])

Output:

b'url1'
b'url2'
b'url3'
b'url4'
b'url5'
