    摘要: The system for measuring a magnetic field comprises a main three-axis sensor (1) for measuring the magnetic field that is able to move together with a carrier (2) capable of generating at least one additional magnetic field that disrupts the measurements of the said main three-axis sensor (1), the said three-axis sensor (1) being designed to provide orthonormal measurements for a reference magnetic field in the absence of magnetic disturbances due to the said carrier (2). The system comprises means (5, 6, 7, 9, 4a, 4b) of adjusting the said main three-axis sensor (1) comprising a removable additional sensor for measuring a magnetic field, that is able to move together with the said carrier (2) and positioned on the outside of the said carrier (2) away from the additional magnetic field or fields.

    摘要: The present invention relates to a system for capturing the movements of a body consisting of substantially rigid segments articulated together and a method for using said system. The system comprises attitude platforms fixed to the segments of the body, said platforms each comprising at least one accelerometer and one magnetometer, and a reduced number of gyrometers. It also comprises a module for detecting pseudo-static states and a module for calculating pseudo-static angles. When all the segments are detected in a pseudo-static state, the state vector is provided by the module for calculating the pseudo-static angles. When a segment is detected in a dynamic state, the state vector is provided at the output of a Kalman filter.
