针对传统人体姿态解算算法中存在的稳定性差和解算精度低等问题,提出一种基于多传感器信息融合的姿态解算算法。利用四元数计算人体的姿态变化,将惯性测量模块的姿态测量值与观测值之间的偏差通过PI调节进行控制;采用互补滤波对多传感器数据进行融合,求取人体实时姿态。实验表明,该算法能够实现稳定地输出高精度姿态数据。

Aiming at the problems of poor stability and short precision in traditional attitude estimation algorithms, a method based on multi-sensor information fusion was proposed.The quaternion was used to calculate the attitude chan-ges, and deviations between measurements and observations from the Inertial Measurement Unit( IMU) were managed by PI regulator.The complementary filtering was adopted for multi-sensor information fusion, and the real-time attitude was got.Experimental results showed that the algorithm could output the high precision attitude steadily.
