Python实现离线文字识别

Python有很多库可以进行文字识别,但不少都是要联网的,而且有的还需要翻墙才能用.对于需要离线进行的文字识别,pytesseract正好可以解决这个痛点.
要使用pytesseract,先要安装Tesseract,该软件有32位和64位,可以在下面的网址下载.
32位:https://digi.bib.uni-mannheim.de/tesseract/tesseract-ocr-w32-setup-v5.0.1.20220118.exe
64位:https://digi.bib.uni-mannheim.de/tesseract/tesseract-ocr-w64-setup-v5.0.1.20220118.exe
下载完成后安装即可.安装包还提供了可供下载的中文简体语言包,也可以联网进行下载.
安装完成后打开安装路径,将它添加到系统变量PATH中.
下面需要安装pytesseract和Pillow两个库.用pip命令安装.
安装完成后我们可以写个程序验证下这个库的功能.我们以下面这幅图片为例.

新建一个Python文件,输入以下代码:

1. from PIL import Image
   
2. import pytesseract
   
3. print(pytesseract.image_to_string(Image.open('E:\sim.jpg')))

复制代码

保存并运行程序,可以查看结果:

我们还可以利用Tkinter结合这个库制作一个GUI文字识别程序.后期本人打算基于这个库开发一个Scribus文字识别插件.
