I think there aren't any algorithm that can do that and won't be for any time soon. I spent several weeks last year recreating my backyard in VR, aiming at 1:1 mapping, using photogrammetry for capture and a standalone mobile headset that allow walking around untethered (Lenovo Mirage Solo). Even with photogrammetry it wasn't as accurate as required for the objects to be placed exactly at the correct position and be able to confidently walk around without fear of hitting a tree that is 20 cm more to the side in VR than in reality. It took many back and forth to get the alignment right. By the time I was done the tomatoes had grown so much the VR environment was already wrong. Outsourcing reconstruction of lost/old places is a great idea. I found that even just stereo-panoramas of old apartments seen in VR (so without positional tracking) is triggering memories in a way that simple photos can't.
