安装 tesseract-ocr-ocr

代码语言:javascript复制
cd tesseract
./autogen.sh
./configure
make
sudo make install
sudo ldconfig

安装完成

输入 tesseract –version 出现一下提示即安装完成

代码语言:javascript复制
➜  tesseract git:(master) ✗ tesseract --version

安装字库

语言包地址:https://github.com/tesseract-ocr/tessdata

由于语言包比较大,这里我们之下英文,中文繁体,中文简体语言包

代码语言:javascript复制
wget --no-check-certificate https://github.com/tesseract-ocr/tessdata/raw/master/eng.traineddata
wget --no-check-certificate https://github.com/tesseract-ocr/tessdata/raw/master/chi_sim.traineddata 
wget --no-check-certificate https://github.com/tesseract-ocr/tessdata/raw/master/chi_tra.traineddata

将语言包移动到tesseract目录下

检查是否安装成功,输入:tesseract –list-langs 出现一下提示视为安装成功

代码语言:javascript复制
➜  tesseract git:(master) ✗ tesseract --list-langs
List of available languages (3):
chi_sim
chi_tra
eng

总结

三步走

第一步,安装相应依赖

第二部,下载源码编译&安装

第三部,安装语言包

最主要的就是依赖部分,可能各种因素使你的依赖不能下载完整,一定按顺序,此博客为踩坑后笔记,笔者按此次总结步骤以安装不下10遍,从本地=》研发=》测试=》预发=》灰度=》生产均无问题
