Creating 3D Models from Light Fields

I don't see any scale reference markers or other reference material in the scene, so I wonder if it recovers scale from light field depth information alone.
Interestingly from the paper, they aren't actually using a light field camera - but rather creating a light volume through sequentially varying the depth of image taken and modeling the volume:
Key to our method is the dense spatio-angular sampling of video, which results in smoothly varying parallax between successive frames
A hack for sure!
I would be curious to know if using a light field camera would even be useful in this scenario as much of what they do mimics the light field camera processes, only manually.
Hopefully lightfield cameras / camera arrays will become more common in the near future.
This means that you know where the light has come from, which allows your to amongst other things alter the focus/depth of field after the image had been captured.
Because you can refocus and change the depth of field post capture, it allows you in theory to do better image segmentation.
