Analysis and image conversion based on this analysis to improve OCR results

I have an OCR project, but it only works with images in which the text is pretty straight and not upside down. (not rotated text) Therefore, I want OCR to be able to recognize any image, even inverted. But I do not know what approaches to solving this problem.

I need something like a string analysis of letters, but even then I can’t determine if the line is upside down or not.

If the images that you perform OCR are in a magazine or book where there is a lot of text on several lines, I suggest trying to find the page turn.
