<p>A method for automatically calibrating sensors in inertial sensor systems during use is presented. Measurement values of a sensor to be calibrated are recorded in at least two different sensor orientations, and the orientations held at the time of measurement are detected simultaneously by a further sensor, which is capable of auto-calibration without any external parameters. A rotation matrix is derived from said different sensor orientations and used together with the measured sensor values for solving an equation for determining calibration coefficients of the sensor, e.g. for compensating a device-inherent offset.</p> |
