Abstract

A stereoscopic marker device includes: a polyhedral cube, including at least four flat surfaces, wherein the at least four flat surfaces are used as one primary marker and at least three secondary markers respectively, the primary marker includes a primary graphic code, the three secondary markers individually include a first secondary graphic code, a second secondary graphic code, and a third secondary graphic code, and the primary graphic code is used for providing spatial coordinate information, which is used for calculating six degrees of freedom (DOF) attitude data; and a spike-shaped body, combined with the polyhedral cube and configured to be fixed on a surgery site.
