Abstract:
Systems and methods are disclosed for determining position and pose of as well as tracking an object in a physical environment based on the emission and sensing of light signals. The derived position, pose and tracking information may be used in a VR/AR environment. The disclosed systems and methods allow for the improved tracking of both active and passive devices. In addition, the disclosed systems and methods enable an arbitrary number of light sensors to be disposed on an object, thereby increasing accuracy and mitigating the effects of occlusion of certain light sensors. Position and pose estimates may be refined and tracked using a filter lattice responsive to changes in observed system states and/or settings. Further, data received from an inertial measurement unit may be used to increase tracking accuracy as well as position and pose determination itself.

Claim (Index 13):
A method for determining the position and pose of an object comprising at least four light sensors, the method comprising:\n deriving angular position relative to an emitter for at least one of the four light sensors based on light received from the emitter at the least one light sensor, the angular position including azimuth, and elevation; determining a number (N) of light sensors that are used to solve a system of equations using the derived angular position, the system of equations comprising at least (N) simultaneous equations, the solution of which provides estimates of the ranges of the (N) light sensors, the number (N) of light sensors being at least three; determining which of the at least four light sensors are used to solve the system of equations; using the system of equations, solving for a range of each of the (N) light sensors; and using a rigid body transform and at least one of the solved for ranges or the derived angular position, determining a rigid-body position for any of the four or more light sensors that were not used to solve the system of equations.
