How to detect if text is rotated 180 degrees or flipped upside down

2024/9/22 1:15:02

I am working on a text recognition project. There is a chance the text is rotated 180 degrees. I have tried tesseract-ocr on terminal, but no luck. Is there any way to detect it and correct it? An example of the text is shown below.
