| Abstract |
Magnetic compasses and accelerometers provide absolute orientation
measurements within the earth’s reference frame. However,
sensor output typically suffers from jitter and external disturbances.
Conversely, visual tracking provides more stable orientation estimation
relative to an unknown initial orientation rather than to true
north. We propose a 3-degree-of-freedom orientation tracking approach
combining the accuracy and stability of vision tracking with
the absolute orientation from inertial and magnetic sensors by estimating
the offset between the initial orientation of the vision tracker
and true north. We demonstrate that the approach improves absolute
orientation estimation on a mobile phone device. |
