笔者环境 centos7 python3
pytesseract只是tesseract-ocr的一种实现接口。所以要先安装tesseract-ocr(大名鼎鼎的开源的OCR识别引擎)。
依赖安装
yum install-y automake autoconf libtool gcc gcc-c++
yum install-y libpng-devel libjpeg-devel libtiff-devel giflib-devel
安装依赖的leptonica库
wget http://www.leptonica.com/source/leptonica-1.72.tar.gz
tar -xzvf leptonica-1.72.tar.gz
cd leptonica-1.72
./configure
make && make install
安装tesseract-ocr
wget https://github.com/tesseract-ocr/tesseract/archive/3.04.00.tar.gz
mv 3.04.00 Tesseract3.04.00.tar.gz
tar -xvf Tesseract3.04.00.tar.gz
cd tesseract-3.04.00/
./configure
make && make install
安装语言包:
wget https://github.com/tesseract-ocr/tessdata/raw/master/eng.traineddata #英文默认包
wget https://github.com/tesseract-ocr/tessdata/raw/master/chi_sim.traineddata #中文繁体
wget https://github.com/tesseract-ocr/tessdata/raw/master/chi_tra.traineddata #中文简体
cp/mv *.traineddata /usr/local/share/tessdata/ #移动下载的包到/usr/local/share/tessdata/ 这个路径下,也可以手动移动
安装pytesseract:
pip install Pillow
pip install pytesseract
至此安装完成,附上使用方法:
import pytesseract
from PIL import Imag
image = Image.open("port_img.jpg")
text = pytesseract.image_to_string(image)
print(text)
