The spatial positioning gyroscope (MTX) inertial sensor used in this paper can be used to measure attitude and direction. Its most prominent advantages are high precision and good flexibility. This paper briefly describes the measurement method of MTX and different output modes of attitude detection data

measures the attitude of the measured human body in different motion states through experiments

and finally processes and analyzes the attitude data output by the system through MATLAB

so as to verify the effectiveness of the attitude detection system.
