Abstract:
In some implementations, a sensing device associated with less than a 360 degree measurement range may obtain a set of signal values. The sensing device may be configured to sense a magnetic field present at the sensing device and collect sensor data based on the magnetic field. The set of signal values may be included in the sensor data collected by the sensing device and may correspond to one or more components of the magnetic field present at the sensing device. The sensing device may determine, based on the set of signal values, a set of calibration points and a set of angular positions. The sensing device may calculate a set of calibration parameters based on the set of calibration points and the set of angular positions. The sensing device may utilize the set of calibration parameters to perform one or more safety checks.
