Patent ID: 11150747

Abstract:
A method of determining respective spatial configurations, indicative of respective positions and orientations, of a plurality of transducers attached to a target object, comprises receiving sensor signals from each transducer. The sensor signals are indicative of respective movements of the respective transducers during an induced movement of the target object. The method includes determining the spatial configurations of the transducers that comprise a first and second subset of transducers. The determining of the spatial configurations of the plurality of transducers comprises (i) obtaining the spatial configurations of the first subset of transducers, and (ii) determining the spatial configurations of the second subset of transducers from the received sensor signals and from the obtained spatial configurations of the first subset of transducers. The determining of the spatial configurations of the second subset of transducers comprises computing object accelerations indicative of accelerations of the target object relative to a reference coordinate system.
