Problems that you may encounter throughout the process

1. (sometimes restarting the software, wrong is nothing, strange is not wrong, I am so) if the console output: "No OCR tool found", indicating that the installation is not successful Tesseract-ocr,debug view Get_available_ Tools, go back in this method to see the OCR library that has been installed in this machine, there are three kinds,

Libtesseract,
Tesseract,
Cuneiform,

This article uses the second kind of tesseract,

Tesseract specific installation please go to.

2. In the identification of pictures with Chinese, will encounter the "Allow_blob_division" error,

Need to download TESSERACT-OCR's Chinese library, address: Https://sourceforge.net/projects/tesseract-ocr-alt/files/tesseract-ocr-3.02.chi_ Sim.tar.gz/download, which contains tesseract multiple text library, Chi_sim.traineddata for the Simplified Chinese library, put the file to C:\Program files (x86) \tesseract-ocr\ Tessdata directory next to the specific processing method, go to: https://www.cnblogs.com/syqlp/p/5462459.html
