An image positioning system capable of real-time positioning compensation includes a 3D marking device, a photographing device, a 3D scanning device, a beam splitter, and a processing unit. The 3D marking device has a polyhedral cube. The beam splitter is configured to cause the photographing device and the 3D scanning device to capture an image of and scan the 3D marking device respectively from the same field of view. The processing unit is configured to calculate image data and 3D scanning data generated respectively by the photographing device and the 3D scanning device to obtain a positioning compensation amount and perform positioning compensation.

Method for real-time positioning compensation of image positioning system and image positioning system capable of real-time positioning compensation

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.
