OCR Software like ABBYY FineReader, but for Solid State Amp low resolution Schematic

[tiefbassuebertr]

Optical Character Recognition software for solid state amplifier schematic symbol recognition to create high resolution schematics from a bad resulution template (like various vintage circuit diagrams, e. g. Threshold CAS-1 and SL-10) wanted.

Until this day I must draw a new circuit diagram, if I want to get a high resolution and lower large PDF file at the same time (see attachement). I don't like that, because this is a very complicated and uncomfortable process.

Who knows a comfortable OCR software in similar kind like the ABBYY FineReader tool, which can transform JPG files with text in doc files ??

Thank you very much for your advices.

I don't think you will find software to perform this task, it's too difficult to write, not many people want/need it, there's no commercial incentive. It's too obscure.

Good luck anyway...

any news?

You can always go old-shool low-tech and enlarge it into a huge sepia for manual clean-up. When I was an intern in college that was one of my main jobs... Of course there may be better software-based ways of doing it now. Could just enlarge and re-work with something as crude as paint? Or re-draw in something like Visio?

Redraw in something like LTspice ORCAD or Circuitmaker is carried out in the moment by old low resolution schematics. Unfortunately much too time-consuming.

This I don't believe. There are not only old amp circuits. There are also old technical drawings (ground-plan) of historical cars, skyscrapers, monuments and much more in low resolution without letters and numbers.
