How can I get the Python source code of Fiducial Registration Wizard module?

Hi, I am a student working at KIST(Korea Institute of Science and Technology).
I want to add my own function to this module. Is it possible?
If possible, can I get the Python source code of Fiducial Registration Wizard module?

Thanks.

The fiducial registration wizard is a c++ module, available here:

I know where it is because I’ve worked with it before, but a method to find it would be:

  • Find out which extension the module came with
  • Internet search that extension name to find it’s documentation (first result is here)
  • Find a link to the source code (bottom right of screen)
