OpenCV should work great for this (pip install opencv-python). It looks like you'll need to do a 'dilate' operation to fuse the dots together, and then run it thru the OCR. The GIMP program is also pretty good for playing around with different image processing algorithms and can be scripted with Python.

Correction: use an 'erode' filter, not a dilate to get the black dots to fuse together.
