Orientation determination device and method, rendering device and method

Abstract

An orientation determination device comprises data input circuitry configured to obtain magnetic field sensor data comprising at least two magnetic field measurements sensed by one or more magnetic field sensors at spatially separate positions and/or in separate frequency ranges and/or at different times and/or at different codes, position input circuitry configured to obtain a position estimate of the one or more positions of the one or more magnetic field sensors, at which the magnetic field sensor data have been acquired, and estimation circuitry configured to derive, from a magnetic map, azimuth and inclination data at the one or more positions of the one or more magnetic field sensors indicated by the obtained position estimate and to estimate the orientation of the orientation determination device based on the obtained magnetic field sensor data and the azimuth and inclination data derived from the magnetic map.
