Requirements

Windows 10. Other Windows versions might work but have not been tested against.

Tesseract windows binary. Can be found at https://github.com/UB-Mannheim/tesseract/wiki

Built using version w64 5.3.0 but later versions should work.

Installation

Downloading the prepackaged binary

Head over to releases, download the .zip and extract it. Install the Tesseract binary and then launch OCRAutomation.exe

The archive contains a manual in Swedish. Feel free to run it through a translation service.

Building your own binary

Install git using Winget in your terminal.

winget install -e --id Git.Git

Clone the repo.

git clone https://github.com/natsukashiixo/OCRAutomation.git

Change directory to the repo.

cd OCRAutomation

Set up a Python virtual environment. Python 3.10.6 is recommended. Because of Pythons various ways to set this up, I recommend researching how to do it yourself if you don't already know how to do it.

Once done, activate your environment.

Install prerequisites using pip.

pip install -r requirements.txt

Change directory to app/src.

cd app/src

Build using pyinstaller and the preconfigured build_specs.spec file. Replace the ./build with the folder where you want the .exe file to end up. Its recommended to not build in the same folder as this repository.

pyinstaller --noconfirm --clean --log-level DEBUG --distpath ./build build_specs.spec

Copy the app/assets folder and its contents into the same folder you built to. For instance, if you built to ./build the final folder structure should be ./build/app/assets

Install the Windows Tesseract binary.

Launch OCRAutomation.exe, on first startup it might take a while because it needs to set up the expected folder structure.

Worth noting:

This project is hardcoded to use the best swedish language model combined with latin script data. If you need to change this you have to edit app/src/modules/run_tesseract.py as well as install the relevant language models yourself.

This project won't be maintained, it was built for one specific purpose at a workplace. Feel free to fork it for whatever reason though!

This is my first project ever, when I started I didn't know how to print hello world in any language. It may be inflexible, inefficient and slow. But it is my firstborn and therefore I think it is beautiful.
