先贴代码：

# 1.Install tesseract-ocr*.exe from http://jaist.dl.sourceforge.net/project/tesseract-ocr-alt/tesseract-ocr-setup-3.02.02.exe
# 2.Install pillow as"pip install form *.whl"
# 3.Install pytesseract as"pip install form *.whl"
import os.path
import pytesseract
from PIL import Image
from jpype import *
