We describe a calibration procedure to track consumer Head Mounted Displays (HMD) using a 3rd party tracking solution. The calibration consists of registering the center of projection of the rendering hardware to a 3rd party tracked object attached to it, and is performed by matching motion datasets from the HMD built-in and 3rd party tracking solutions. We demonstrate this calibration with an augmented reality optical see-through HMD, where the correctness of the alignment is critical to the visual match of a real object by a virtual overlay. We assessed a mean error of 3mm (SD = 1mm) for objects at a distance of 70cm in the projected overlay image.
