摘要：
Disclosed are systems, methods, and techniques for registering a HMD coordinate system of a head-mounted display (HMD) and a localizer coordinate system of a surgical navigation localizer. A camera of the HMD captures at least one image of a registration device having a registration coordinate system and a plurality of registration markers. The registration markers are analyzed in the at least one image to determine a pose of the HMD coordinate system relative to the registration coordinate system. One or more position sensors comprised in the localizer detect a plurality of tracking markers comprised in the registration device to determine a pose of the registration coordinate system relative to the localizer coordinate system. The HMD coordinate system and the localizer coordinate system are registered using the registration device, wherein positions of the registration markers are known with respect to positions of the tracking markers in the registration coordinate system.
