Patent Images
1. An infrared tracking system, comprising:
- a computing device;
one or more tracking cameras;
non-transitory media storing instructions readable by the computing device, that when executed by the computing device, cause the computing device to;
receive image data from the one or more tracking cameras, the received image data comprising image data corresponding to infrared light pulses emitted from a first plurality of infrared light sources affixed to a moveable object;
based at least in part on the received image data, detect a first pattern of infrared light pulses;
identify from the first pattern of detected infrared light pulses the presence of at least a first infrared light source and a second infrared light source of the first plurality of infrared light sources; and
calculate a first orientation of the moveable object based at least in part on the identified presence of the first infrared light source and the second infrared light source, wherein the first orientation is defined using at least five degrees of freedom.

Abstract
Embodiment of a lightweight and compact wireless precision position tracking device and a precision position tracking motion capture system are described. Optionally, the wireless precision position tracking device is configured to be worn by a user. The wireless precision position tracking device may be configured to emit optical light from two or more respective markers, where the light from one of the markers is distinguishable from light from another of the markers.

11. An infrared tracking system, comprising:
-
a computing device; non-transitory media storing instructions readable by the computing device, that when executed by the computing device, cause the computing device to; receive image data, the received image data comprising image data corresponding to infrared light pulses emitted from a first plurality of infrared light sources; based at least in part on the received image data, detect a first pattern of infrared light pulses; determine from the first pattern of detected infrared light pulses the presence of a first infrared light source and a second infrared light source of the first plurality of infrared light sources; and calculate a first position of the first and second infrared light sources based at least in part on the determined presence of the first infrared light source and the second infrared light source.

22. An infrared tracking system, comprising:
-
a computing device; non-transitory media storing instructions readable by the computing device, that when executed by the computing device, cause the computing device to; receive image data, the received image data comprising image data corresponding to infrared light pulses emitted from a first plurality of infrared light sources comprising a first infrared light source and a second infrared light source, wherein the first infrared light source emits a first infrared light pulse pattern and the second infrared light emits a second infrared light pulse pattern, the second infrared light pulse pattern different than the first infrared light pulse pattern; distinguish from the received image data the presence of each light source of the first and second infrared light sources; and calculate a first orientation of the first and second infrared light sources based at least in part on the distinguished presence of the first and second infrared light sources.
