Hey! Camelot maintainer here. You can check out this doc for details on how Camelot extracts tables from PDFs: https://camelot-py.readthedocs.io/en/master/user/how-it-work...

As pointed out in this thread, right now it only works with text-based PDFs. But there's a PR[1] which will add OCR support (using EasyOCR) for image-based PDFs in some time.
