Abstract

The invention discloses a gyroscope inertial measurement method, which comprises the steps of performing magnetic field measurement according to a first operation instruction and determining an initial magnetic field signal strength value; performing inertial measurement and determining an inertial signal strength value; performing magnetic field measurement and determining a magnetic field signal strength value; determining a magnetic field environment signal strength value, wherein the magnetic field environment signal strength value is an average value of the magnetic field signal strength value and the initial magnetic field signal strength value; determining an inertial output value, wherein the inertial output value is a difference value of the magnetic field environment signal strength value and the inertial signal strength value; outputting the inertial output value. According to the method disclosed by the invention, magnetic field measurement results are utilized as inertial measurement parameters, so that inertial measurement accuracy is greatly improved; furthermore, the inertial output value is prevented from being affected in a situation that disturbance is generated by a magnetic field, and robustness is good.
