Hello sir,
i'm python developper, i worked on many OCR projects that include medical parameter detection, get some identification number, date.
i worked with tesseract and easyocr before, sometimes it is useful to do some image processing before sending the image to OCR, or maybe if you can go for some payable services like google vision it would be good.
from my experience google vision is very powerful and can bring more value to your project,
i'm looking forward to work with you.
cordially.
