Abstract

Low-cost micro inertial measurement unit (MIMU) generally has low accuracy, and needs to be calibrated beforehand in practical engineering applications. Aiming at the problems of separate calibration of accelerometers and gyroscopes, complicated steps, and difficulties in batch calibration in traditional calibration methods, firstly, by analyzing the common features of the accelerometer and gyroscope error model, a unified calibration model based on the principle of least squares is established, which can be used to calibrate the accelerometers and gyroscopes at the same time, and finally a batch calibration test was carried out on several MIMUs, and the accuracy after calibration is comparable to that obtained by the traditional calibration method, which meets the requirements of engineering applications.
