Accelerometer calibration method based on Frank-Wolfe method

The invention discloses an accelerometer calibration method based on a Frank-Wolfe method, and the method comprises the following steps: S1, analyzing the error form of an accelerometer, determining the parameters, needing to be solved, of the accelerometer, and constructing a calibration error model based on the calibration error of the accelerometer; s2, calibrating the accelerometer by adopting a multi-position rotation calibration method, calibrating the error of the accelerometer according to the principle that the acceleration is equal to the local gravitational acceleration when the accelerometer is static, constructing an error model of the accelerometer, and establishing an identification model when the MEMS accelerometer outputs N data samples; s3, calibrating the accelerometer by adopting a six-position rotation calibration method, respectively acquiring data samples of original output values of the accelerometer at six different positions, and substituting the data samples into the error model; so
