Video showing the new extrinsic calibration procedure to align a 3D camera such as Microsoft's Kinect with a 3D tracking system such as HTC Vive's Lighthouse.

A flat disk (a CD/DVD covered in paper on both sides) is attached to a controller or other tracked object, and shown to the camera in several different positions, and several different orientations, throughout the tracked space. As tie points are collected, the software updates the tracker-camera calibration in real time, and finally saves it as the camera's persistent extrinsic calibration.
