transformation - Detect transform from detection of QR code?


I want to calculate the transform I need to render a 3D object in my world.


How I see my idea:



  • You open a camera

  • You point it at a QR code

  • The app detects the QR code and returns the 4 corners and the correct direction

  • The app calculates the transform that this QR code is currently at (I need help with this step)

  • The app uses that transform to render the 3D object in a fixed position over the QR code



I want something like Vuforia, but for QR codes (as they are used often).


I don't really know how I can extract the transform from the detected QR code (I will get the location of the 4 corners)
