You can try Google ML Kit's text recognition API (https://developers.google.com/ml-kit/vision/text-recognition/android) and feed it with the cropped image inside the rectangle. — Dong Chen, Jul 13 '21 at 18:43

Here is a similar question with some solutions you can take a look. Is there a way to crop Image/ImageProxy (before passing to MLKit's analyzer)?

Another idea is not cropping the image, instead filtering out the barcode result (based on the bounding box) if it's not in the specified area.
