关于python:mac-安装tesseract与pytesseract使用

tesseract装置配置

装置依赖

brew install automake autoconf libtoolbrew install pkgconfigbrew install icu4cbrew 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.shmkdir buildcd 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/pkgconfigmake -j# Optionally install Tesseract.sudo make install# Optionally build and install training tools.make trainingsudo 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 stdout0 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 ptfrom PIL import Imageimage = Image.open('0384.jpeg')text = pt.image_to_string(image)print(text)
