title: how to reconstruct in 3d of a scene from two images
body: <p>I wish to make a 3D reconstruction of a scene. For that, I have 2 images of the scene taken from two different angles.
  Is there a library that does that? (I work in python)
  if not, what are the steps that must be followed?
  if you have the code ready, it is welcome.
  thanks </p>
