环境：ubuntu + python2.7

        代码：

#/usr/bin/env python
# -*- coding: UTF-8 -*-

from PIL import Image
import pytesseract
text=pytesseract.image_to_string(Image.open('/root/Desktop/444.jpg'),lang='chi_sim')
print(text)

        效果：

        步骤：

                1：这里我们需要用到两个库：pytesseract和PIL

                2：同时我们还需要安装识别引擎tesseract-ocr

                3：下载中文简体字库chi_sim.traineddata

        安装pytesseract和PIL

                pip install PIL 

                pip install pytesseract 

        安装识别引擎tesseract-ocr

                安装Tesseract

                sudo apt-get install tesseract-ocr

                安装中文

                sudo apt-get install tesseract-ocr-chi-sim

        下载中文简体字库
