tesseract 装置配置
装置依赖
brew install automake autoconf libtool
brew install pkgconfig
brew install icu4c
brew install leptonica
# Packages required for training tools.
brew install pango
# Optional packages for extra features.
brew install libarchive
# Optional package for builds using g++.
brew install gcc
下载解压 tesseract
tesseract
编译装置
cd tesseract-4.1.1
./autogen.sh
mkdir build
cd build
# Optionally add CXX=g++-8 to the configure command if you really want to use a different compiler.
../configure PKG_CONFIG_PATH=/usr/local/opt/icu4c/lib/pkgconfig:/usr/local/opt/libarchive/lib/pkgconfig:/usr/local/opt/libffi/lib/pkgconfig
make -j
# Optionally install Tesseract.
sudo make install
# Optionally build and install training tools.
make training
sudo make training-install
下载 eng.traineddata
eng.traineddata
这里只有下载其中的 eng.traineddata 就行了,如果须要其余的语言则按需下载,不须要全副都下载了,全副下载的话 3g 左右,比拟大。
测试
$ tesseract 0384.jpg stdout
0 3 8 4
看报错门路,把 eng.traineddata 文件拷贝到缺失门路下,再次测试
pytesseract 应用
参考
依赖包装置
pip install pytesseract
导入应用
import pytesseract as pt
from PIL import Image
image = Image.open('0384.jpeg')
text = pt.image_to_string(image)
print(text)
