Abstract
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.
