If you want to do THAT, then you need to know the distance of the object in front of the center of the camera view which you want to maintain it's scale.
But other than that I don't know how to dtermine how far forward you need to move the camera to maintain the scale of the object at that position.
That badger animation website has an animation called Scampi which uses this effect. It's pretty cool.
