Patent Images
1. A navigation system for tracking an object, said navigation system comprising:
- a plurality of optical sensors;
a tracker for mounting to the object, said tracker including three markers and a non-optical sensor, wherein said plurality of optical sensors are configured to receive optical signals sequentially from said markers and said non-optical sensor is configured to generate non-optical signals; and
a computing system including at least one processor configured to;
determine a position of a first of said markers at a first time based on a first optical signal from said first marker;
determine positions of a second and third of said markers at said first time based on said first optical signal and a non-optical signal from said non-optical sensor; and
correlate said determined positions of said first, second, and third markers to the object to track a position of the object.

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.
