一、安装linux下图片处理工具:
# which tesseract
/usr/bin/tesseract
二、安装python连接模块：
pip install pytesseract
pip install Pillow
三、进入python运行环境：

）
修改源码：
vim /usr/lib/python2.7/site-packages/pytesseract/pytesseract.py
修改为绝对路径：（
tesseract_cmd = ‘/usr/bin/tesseract‘
）
>>> import pytesseract
>>> from PIL import Image
>>> image = Image.open(‘/tmp/cap.jpg‘)
>>> vcode = pytesseract.image_to_string(image)
>>> print(vcode)
