In the book Mastering OpenCV with Practical Computer Vision Projects, chapter 5, by David Escrivá explain plate detection as well as OCR on letters and numbers. The code is available on Gihub here. I think it better to see the whole process than to focus on each stage (in the first approach). After, when everything is working, you may want to focus on some part of recognition, like precise number/letter extraction.
