Title:
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
Document Type and Number:
WIPO Patent Application WO/2012/072961
Kind Code:
A3
Abstract:
The invention relates to a method for determining the values of parameters representative of a movement of an entity represented by an articulated line, using a sensor unit comprising at least one sensor for sensing a parameter representative of an orientation of a first segment of the articulated line, which comprises the following steps: receiving an orientation value measured and supplied by the orientation sensor; and estimating a value of at least one first parameter representative of a movement of the first segment by processing the supplied attitude value. The method further comprises the following step, carried out on the basis of a predetermined motion model of the articulated line, referred to as time variation model, comprising at least one time-dependent relationship between said at least one first parameter and at least one other parameter representative of a movement of another segment of the articulated line: estimating a value of said at least one other parameter by applying the time variation model to the estimated value of said at least one parameter.
