I have a populated PCB, and I want to draw a circuit diagram of it.

For printed documents, you have OCR which can recognize text in an image. Is something similar available for PCBs? i.e. I provide photos of the front and back of the PCB, and the software recognizes the components, their values and how they're connected?

I realize this would be limited (the sw can't see PCB traces covered by components, multilayer PCB etc), but is it possible at all?

How complex are the PCBs you want to analyze? This might work for very oldish 2-layer PCBs, but modern PCBs have 20 layers or so. No way these can be analyzed with a camera. – PMF Apr 15 '21 at 12:14
the one I'm looking at now is a simple 1-layer PCB. – Hobbes Apr 15 '21 at 12:52
Do you want to automate it for multiple PCBs or do you want it for one? – Dennis Ernst Apr 15 '21 at 13:00

Some carbon based units can do it. – Kartman Apr 15 '21 at 13:02
I've got only one PCB at the moment. I can figure this one out by hand, just wondering if there's a better way. – Hobbes Apr 15 '21 at 13:20

Even if there is such a tool, it would be highly unreliable. Even humans can't do it using vision only, they need to use other tools too – Eugene Sh. Apr 15 '21 at 13:58
