python自动截取需要区域，进行图像识别实践！

import os
os.chdir("G:\Python1\Lib\site-packages\pytesser")
from pytesser import *
from pytesseract import image_to_string
from PIL import Image
from PIL import ImageGrab


#截图，获取需要识别的区域
x = 345
y = 281
m = 462
n = 327

k = 54
for i in range(2,6):
    box = (x,y,m,n)
    img = ImageGrab.grab(box)
    img.save("G:\Python1\Lib\site-packages\pytesser\kangkang"+str(i)+".png")
    #img.show()
    y+=54
    n+=54

#截图完毕后，开始图像识别
names=["kangkang2.png","kangkang3.png","kangkang4.png","kangkang5.png"]
for name in names:
    im = Image.open(name)
    text = image_to_string(im)
    print(name+":"+text)
