Abstract
An evaluation device and method for orientation estimation for two sensor units arranged on an object. The method including: ascertaining a sensor transformation matrix from a first sensor coordinate system fixed to a first sensor unit into a second sensor coordinate system fixed to a second sensor unit; transforming a first acceleration vector measured using the first sensor unit into the second sensor coordinate system; and defining a first axis {tilde over (x)} located in the second sensor coordinate system, corresponds to a first coordinate x of an object coordinate system extending through the first sensor unit and the second sensor unit, the object coordinate system being fixed to the object, based on the second angular velocity vector, its time derivative, and a difference vector between a second acceleration vector measured using the second sensor unit minus the first acceleration vector transferred into the second sensor coordinate system.
