Abstract
A method for measuring movement of a solid, using an absolute measurement associated with a double integration measurement. The method can be applied in particular to sensing movements of the human body and includes a series of measurement of the acceleration of the solid and double integration of the measurements to obtain successive values of a first translation of the solid, and a series of absolute measurements of at least one second degree of freedom of the solid, namely a rotation, and this measurement of rotation is converted into a measurement of translation used to update the first translation.

A method for measuring movement of a solid, in which at least one first translation of the solid is measured, the method comprising:
- a series of measuring acceleration of the solid and making double integration of the measurements, to obtain successive values of the first translation;
- a series of absolute measurement of at least one second degree of freedom of the solid, the second degree of freedom being a rotation, by at least one rotation sensor;
- converting the measurement of rotation into a measurement of translation;
- and
- using the translation measurement to update the first translation.
