Any OTB score sheet OCR (optical character recognition) ?

Is there any OCR phone app to convert a picture of a score sheet into a PGN? (Prefer phone app since the phone already has built-in camera; but if there isn't something for the phone, then computer will do).  Preferably free and with no ads.

Does anybody know of one?

Thanks!

Thinking a little more, OCR may not work well, maybe some limited handwriting recognition.

Anyway, I can't seem to find anything.

Does anybody know of one?

Seems like a useful app to have at tournaments. 

Maybe chess is just not popular enough for people to write something like this (I mean, chess isn't all that popular and then only a subset plays OTB, and then only a subset of that subset play tournaments where score keeping is done).

Maybe I'll write this app (it'll be free and without ads of course).  Seems not too difficult; but then the devil is in the details in these things (yes, I never learn.)

Good luck!

Well, it might not work for you then : )

Fortunately, my son's score sheets are very much more readable.

I write these little apps just for my own use (and make them available free to the public).  So there is no requirements other than what I personally require.

I did some testing using an OCR library and it actually worked kind of OK; i.e., can recognize a lot of the image.  I think this project might be a lot easier than I initially thought.  But yeah, yeah, I know, the devil is always in the details.

Anyway, I think I may actually have something where I can snap a pic of score sheet and out comes a PGN in the email : )
