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.
