Using tracking data with Armature

So I want to track a person so I can add things on top of them, like for example a suit or something.

So far here is what I’ve learned (Please tell me if I got something wrong):

  • I have to put tracking markers on the actor to correspond with the bones on the armature
  • In blender I can track each point and add the tracking data to an empty

So what I want to know:

  • How do I take the tracking data and make it move the armature
  • What if a tracking point goes out of frame? Or the actor rotates there arm? How do I continue tracking?

Thanks in advance.
