Abstract

A method for the computer-aided calculation of the movement of an object using sensor data from a sensor arranged on the object is provided. The sensor data comprise measuring point set measured at different time points, and the movement of the object is determined between different measuring point sets. From the measuring point sets, initially structural information is extracted and stored together with the measuring points that are not to be associated with any structural type. Subsequently, associations between the structural elements with the same structure type are determined and a corresponding transformation for representing the structural elements is performed. An association of the unassignable measuring points and the structural elements is created and a corresponding transformation of the superimposed associated measuring points and structural elements is performed. The structural elements or measuring points are associated preferably by a statistic method taking into account a measuring noise of the sensor.
