HandPoseEstimationExample in 3D, or distance to palm

[thePostFuturist]

In the example class, I only see 2D coordinates for landmarks. Is it possible to obtain depth, or at least unit distance to palm?

I have just barely ported the opencv model zoo example, so I am not that familiar with hand pose estimation.
Here is the original code.

It may be possible to roughly estimate the distance to the palm based on average human hand size and camera parameters, but I have not tried.
