A comparative accuracy analysis of five sensor fusion algorithms for orientation estimation using magnetic and inertial sensors

Introduction: Magnetic and Inertial Measurement Units (MIMUs) are extensively used in movement analysis. The absolute orientation of the MIMU can be estimated by fusing the information recorded by a tri-axial accelerometer, gyroscope, and magnetometer. The majority of the sensor fusion algorithms proposed in the literature are either based on Kalman filter or complementary filtering approaches. Despite the number of proposed formulations, no well-established conclusions about the best performing algorithms have been reached yet.
