accelerometerInitialBiasAsTriad

Gets initial bias coordinate used as an initial guess. This value is determined once the calibrator starts. If accelerometerSensorType is AccelerometerSensorType.ACCELEROMETER_UNCALIBRATED, this will be equal to the values used internally by the device as part of the accelerometer hardware calibration. If accelerometerSensorType is AccelerometerSensorType.ACCELEROMETER, then accelerometer sensor measurements are assumed to be already bias compensated, and the initial bias is assumed to be zero. If isAccelerometerGroundTruthInitialBias is true, this is assumed to be the true bias, and estimatedAccelerometerBiasAsTriad will be equal to this value, otherwise estimatedAccelerometerBiasAsTriad will be the estimated bias after solving calibration, which will differ from estimatedAccelerometerBiasAsTriad.
