Abstract:
1. A computer-implemented method for calibrating a sensor device, comprising: obtaining, by a device, a measurement reading from the sensor device, wherein the measurement reading is a output signal from the sensor device to determine movement; determining, by the device, if the sensor device is in a steady state based at least partly on the measurement reading, wherein the steady state is a condition where the output signal of the sensor device is expected to be stable and wherein stability of the sensor device is determined by not being subject to movement; storing, by the device, data obtained from the measurement reading in a memory if the sensor device is in the steady state; and calibrating, by the device, the sensor device at least partly on the stored data, wherein calibrating comprises fitting an ellipsoid to collected steady points to produce calibration parameters.
