Computer Vision ALPR

I am interested in doing a project on Automatic number plate recognition using raspberry pi3. I dont know how to start and i am also not sure of how to proceed with this project. I would like to have some guidance. I know basics of opencv yet i am not sure. Please Help.

I immediately thought of this article I ever read: https://medium.freecodecamp.org/how-i-replicated-an-86-million-project-in-57-lines-of-code-277031330ee9 . There is some code in there, but I don’t know if it is that useful. However, it sure is fun to read.

Also, just Googling may be a good starting point: https://www.google.com/search?q=raspberry+pi+alpr .

If you have more specific questions, you can post them back there. Someone here could write an entire guide - but apparently other people already did it.
