3d pose estimation? Z axis 

Any idea how to get a 3d pose estimation out of this? The resulting data has no z axis - so it is just as flat as the source image. This would be much more impressive if we could apply it to an actual skeleton and use in something like threejs or even export to blender

Do we need to apply some sort of a matching after we get the 3d pose? If so what is the best approach for this to do in js?
