一.安装tesseract

1.下载链接

https://digi.bib.uni-mannheim.de/tesseract/

2.网盘下载地址

链接：https://pan.baidu.com/s/1CLPSf2TahIGaeL7zRCTQDg
提取码：x0kn

3.配置环境变量

3.1配置TESSDATA_PREFIX变量

3.2配置Path变量

 4.验证是否安装成功：

C:\Users\特昂糖>tesseract -v
tesseract 4.00.00alpha
 leptonica-1.74.1
  libgif 4.1.6(?) : libjpeg 8d (libjpeg-turbo 1.5.0) : libpng 1.6.20 : libtiff 4.0.6 : zlib 1.2.8 : libwebp 0.4.3 : libopenjp2 2.1.0

5.命令行使用 tesseract --list-langs命令可查看当前软件支持的语言

C:\Users\特昂糖> tesseract --list-langs
List of available languages (2):
eng
osd

6.拓展语言包

到https://github.com/tesseract-ocr/tessdata下载需要的的语言包，如下图，红框内为中文简体语言包，下载后将该包直接放在程序安装目录的tessdata文件夹里面即可。

二.安装pytesseract

安装命令：pip install pytesseract

C:\特昂糖>pip install pytesseract

因为网络缘故下载不下来，用国内的源下载：

三.python代码

import pytesseract
from PIL import Image

file=r'F:/png/db63fc936bb07673a375423ce2d2cf8.png'
image=Image.open(file)
print(pytesseract.image_to_string(image,lang='chi_sim'))

---

输出结果：

元 日

王 安 石 ( 宋 代

爆 竹 声 中 一 岁 除 , 春 风 送 暖 入 属 苏 。
干 门 万 户 瞳 嘻 日 , 总 把 新 桃 换 旧 符 。
