1、安装依赖
# Packages which are always needed. 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
2、下载解压tesseract-4.1.1.tar.gz
https://github.com/tesseract-ocr/tesseract/releases
3、编译安装
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
4、下载eng.traineddata
https://github.com/tesseract-ocr/tessdata
5、测试
$ tesseract 0384.jpg stdout 0 3 8 4
图片
看报错路径，把eng.traineddata文件拷贝到缺失路径下，再次测试
