摘要：
Disclosed is a method for estimating the relative orientation between a tibia (11a) and a femur (11b), said method involving the steps of: • having first inertial measuring means (20a) and second inertial measuring means (20b) acquire reference accelerations and reference angular velocities during at least one reference movement of the lower limb (10) • estimating a plurality of morphological parameters • determining a relative orientation between the tibia (11a) and the femur (11b) in the starting position in accordance with the morphological parameters • having the first inertial measuring means (20a) and the second inertial measuring means (20b) acquire working angular velocities during a working movement of the lower limb (10) • estimating the relative orientation between the tibia (11a) and the femur (11b) in accordance with the measured working angular velocities and the relative orientation in the starting position.
