Abstract
A mixed reality system includes a head-mounted device (HMD) having an HMD coordinate system and a camera to capture images. A localizer has a localizer coordinate system and position sensors supported by a housing to track a pose of a real object. Registration markers are configured to be recognized from the captured images of the camera of the HMD. The registration markers are disposed on the housing of the localizer in a predetermined spatial relationship with respect to the localizer coordinate system. At least one controller is configured to utilize the registration markers recognized from the captured images to register the localizer coordinate system and the HMD coordinate system.
