1. A navigation system comprising:
- a localizer;
a tracker for communicating with said localizer and including three markers and a non-optical sensor; and
a computing system having at least one processor configured to;
determine positions of each of said markers in a first coordinate system based on optical and non-optical signals,determine a position of a virtual point in said first coordinate system, andmatch said positions of said markers and said virtual point in said first coordinate system with positions of said markers and said virtual point in a model of said tracker established relative to a second coordinate system to obtain a transformation matrix to transform said second coordinate system to said first coordinate system.

Abstract
Systems and methods that utilize optical sensors and non-optical sensors to determine the position and/or orientation of objects. A navigation system includes an optical sensor for receiving optical signals from markers and a non-optical sensor, such as a gyroscope, for generating non-optical data. A navigation computer determines positions and/or orientations of objects based on optical and non-optical data.

12. A method of tracking an object using a navigation system comprising alocalizer, a tracker including three markers and a non-optical sensor, and a computing system having at least one processor, said method comprising the steps of:
-
determining, with the at least one processor, positions of each of the markers in a first coordinate system based on optical and non-optical signals; determining, with the at least one processor, a position of a virtual point in the first coordinate system; and matching the positions of the markers and the virtual point in the first coordinate system with positions of the markers and the virtual point in a model of the tracker established relative to a second coordinate system to obtain a transformation matrix to transform the second coordinate system to the first coordinate system. - View Dependent Claims (13, 14, 15, 16, 17, 18)
