Second video showing the inverse extrinsic calibration procedure, where it is now the 3D camera that is rigidly attached to a tracked object, and the calibration disk is at a fixed position in world space. This setup could, for example, be used to record more dynamic mixed-reality footage of a VR application with a moving camera.

The calibration procedure is very similar, only that now the camera needs to be aimed at the calibration disk from a variety of positions and orientations.
