Python 代码如下

#!/usr/bin/python
# -*- coding:utf-8 -*-
from PIL import Image
import pytesseract

def recognize_captcha(img_path):
    im = Image.open(img_path).convert("L")
    threshold = 140
    table = []
    for i in range(256):
        if i < threshold:
            table.append(0)
        else:
            table.append(1)

    out = im.point(table, '')
    num = pytesseract.image_to_string(out)
    return num

if __name__ == '__main__':

    img_path = "D:\\1flower\\test2.jpg"
    res = recognize_captcha(img_path)
    strs = res.split("\n")
    if len(strs) >=1:
        print (strs[0])
