digits.traineddata is clearly at /usr/local/share/tessdata/digits.traineddata. Any idea what the problem could be? Using the "eng" language works as expected.

You need to download 'raw' file from github. Use download link.

FreeGoldRush commented 4 years ago

Now it works, but I'm getting about the same results that I did with '-l eng'. Hmmm... Need to do some more testing.

Shreeshrii commented 4 years ago

You can try whitelist with eng.traineddata.

A whitelist with ‘-l eng’ is actually what I am doing now. Was trying to get a better response for numbers only.

Where can I find instructions on how to train it? I can put together a training set with thousands of images and the proper 8 digit code that should be scanned from each image. The images offer a wide variety of photo quality. Is this sufficient information to make my own .traineddata file?

Thanks again.

Mike

Check out tesseract-ocr/tesstrain repo to train using images
