Abstract

A method of tracking 3D position and orientation of an entity in a moving platform is described. The method comprises receiving data sensed by an inertial measurement unit mounted on the entity. Visual tracking data is also received, computed from images depicting the moving platform or the entity in the moving platform. The method computes the 3D position and orientation of the entity by estimating a plurality of states using the visual tracking data and the data sensed by the inertial measurement unit, where the states comprise both states of the moving platform and states of the entity.
