Simulink scheme text and block recognition - how to approach

Hello everyone,

Im facing to some challenging problem and i would like to discuss and share some ideas with you.

I need to create tool which should be able to representing Simulink block scheme as a text. This text will be used as a requirement for another documents. In ideal case - you will import picture of model in simulink to this tool and it should be able to say you for example : output1 is represented as a logical OR of function fcn1 and fcn2.

(or simply something like input 1 and Input 2 goes to block AND1...)

I would like to ask whats the best way how to do it. I was thinking about some deep learning process or image recognition (can work for blocks) and OCR (for text - i already tried).

Or maybe try to export simuilnk block to matlab ( i did it with some easy script) - but there is a issue that im not able to export signal names. Or is there any way how to do it? If i can extract all needed data (types of blocks, signal names...) there should be way how to make some tool.

Im also able to generate C code from Simulink and see the conditions.

Thanks for your help and any ideas, im open to all kind of interesting solutions, i would like to improve my skills in Matlab on this project.
