Method and system for determining the values of parameters representative of a movement of at least two limbs of an entity represented in the form of an articulated line

摘要

A method determining values of parameters representing a movement of an entity represented by an articulated chain, by a sensor assembly including at least one sensor for a parameter representing an orientation of a first segment of the articulated chain, the method including: reception of an orientation value measured and supplied by the orientation sensor; estimation of a value of at least one first parameter representing a movement of the first segment by processing the orientation value; and, based on a predetermined movement model of the articulated chain, as a time change model, including at least one relationship of time dependency between the at least one first parameter and at least one other parameter representing a movement of another segment of the articulated chain: estimation of a value of the at least one other parameter by application of the time change model to the estimated value of the at least one first parameter.

1. A method for determining, by a sensor assembly including at least one orientation sensor, values of parameters representing a movement involving at least two limbs of an entity represented in a form of an articulated chain in which each limb is represented by at least one segment and the at least two limbs are connected together by an articulation, the sensor assembly including the at least one orientation sensor being fixed to the entity and configured to measure a parameter representing an orientation of a first segment of the articulated chain, the method comprising:
receiving an orientation value measured and supplied by the orientation sensor; estimating a value of at least one first parameter representing a movement of the first segment by processing of the supplied orientation value; and estimating a value of at least one other parameter by executing a time-change model on the basis of a predetermined movement model of the articulated chain, the time-change model including at least one relationship of time dependency between the at least one first parameter and the at least one other parameter representing a movement of another segment of the articulated chain.
