Abstract
A system for capturing the movements of a body having substantially rigid segments articulated together includes attitude units fastened onto the segments of the body, the units each including at least one accelerometer and one magnetometer, and a reduced number of gyroscopes. The system also includes a pseudo-static state detection module and a module for calculating pseudo-static angles. When all segments are detected in a pseudo-static state, the state vector is provided by the module for calculating pseudo-static angles. When a segment is detected in a dynamic state, the state vector is provided at the output of a Kalman filter.
