The invention provides a method and an apparatus for determining an angle of rotation of an object about an axis of rotation. The method has the steps of: measuring (S01) a first acceleration profile of an acceleration sensor (10) fitted to the object (12) during a first period of time; and calculating (S05) the angle of rotation (α), through which the object (12) has rotated about the axis of rotation (D) during the first period of time, on the basis of the first accelerations during the first period of time and on the basis of a predetermined distance (d) between the acceleration sensor (10) and the axis of rotation (D). The apparatus comprises an acceleration sensor (10) which can be fitted to the object (12); and a computing device which is designed to determine the angle of rotation (α) on the basis of an acceleration profile measured by the acceleration sensor (10) during a period of time and on the basis of a predetermined distance (d) between the acceleration sensor (10) and the axis of rotation (D). |
