【干货】centos下搭建图像文字识别

下载

1. wget https://github.com/tesseract-ocr/tesseract/archive/4.1.0.tar.gz

2. leptnica下载地址：https://gitee.com/mirrors/leptonica.git

安装依赖：yum install autoconf automake libtool libjpeg-devel libpng-devel libtiff-devel zlib-devel gcc gcc-c++ gcc-g77

安装leptonica

1. tar -xzvf leptonica-1.74.4.tar.gz

2. cd leptonica-1.74.4

3. ./autobuild

4. ./configure --prefix=/usr/local/leptonica

5. make

6. sudo make install

配置一下 leptonica 的环境变量。

打开 /etc/profile

1. vim /etc/profile

添加以下字段

1. PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/leptonica/lib/pkgconfig

2. export PKG_CONFIG_PATH

3. CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:/usr/local/leptonica/include/leptonica

4. export CPLUS_INCLUDE_PATH

5. C_INCLUDE_PATH=$C_INCLUDE_PATH:/usr/local/leptonica/include/leptonica

6. export C_INCLUDE_PATH

7. LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/leptonica/lib

8. export LD_LIBRARY_PATH

9. LIBRARY_PATH=$LIBRARY_PATH:/usr/local/leptonica/lib

10. export LIBRARY_PATH

11. LIBLEPT_HEADERSDIR=/usr/local/leptonica/include/leptonica

12. export LIBLEPT_HEADERSDIR

应用配置

1. source /etc/profile

OK，现在我们就可以开始安装 tesseract。

安装 tesseract

1. tar -xzvf 4.1.0.tar.gz

2. cd tesseract-4.1.0

3. ./autogen.sh

4. ./configure --prefix=/usr/local/tesseract

5. make

6. sudo make install

接下来配置 tesseract 环境变量

打开 /etc/profile

1. vim /etc/profile

追加以下字段

1. PATH=$PATH:/usr/local/tesseract/bin

2. export PATH

应用配置

1. source /etc/profile

测试一下：

1. tesseract -v

上传 tesseract训练数据

下载地址：https://gitee.com/superaskar/tessdata.git

解压所有文件到/usr/local/tesseract/share/tessdata目录下

测试 tesseract

上传一张图片到/opt/tools目录，并进入该目录，然后输入命令

tesseract t1.png t1opt -l chi_sim
