More Information
Summary:The present invention relates to a tool system comprising a handheld implement having a passive vectorized tracking marker permanently integrated with the implement at a predetermined location on the implement in a predetermined orientation with respect to the implement; and a database comprising geometric information describing the at least one of a rotationally asymmetric shape of the tracking marker and a rotationally asymmetric pattern disposed on the tracking marker. The system may further comprise: a tracker configured for obtaining image information about the tracking marker when the tracking marker is in a field of view of the tracker; and a controller having a processor and memory, the controller in communication with the database and the tracker, the processor programmable for receiving and processing image information from the tracker; accessing the database to retrieve the geometric information; and comparing the image information with the geometric information. The handheld implement may be three-dimensionally tracked by the tracker.
