public class TurntableGyroscopeCalibrator extends Object implements GyroscopeNonLinearCalibrator, UnknownBiasGyroscopeCalibrator, GyroscopeCalibrationSource, GyroscopeBiasUncertaintySource, UnorderedStandardDeviationBodyKinematicsGyroscopeCalibrator, AccelerometerDependentGyroscopeCalibrator
Estimates gyroscope biases, cross couplings and scaling factors along with G-dependent cross biases introduced on the gyroscope by the specific forces sensed by the accelerometer.

This calibrator assumes that the IMU is placed flat on a turntable spinning at constant speed, but absolute orientation or position of IMU is unknown. Turntable must rotate fast enough so that Earth rotation effects can be neglected, bus slow enough so that gyroscope readings can be properly made.

To use this calibrator at least 10 measurements are needed when common z-axis is assumed and G-dependent cross biases are ignored, otherwise at least 13 measurements are required when common z-axis is not assumed. If G-dependent cross biases are being estimated, then at least 19 measurements are needed when common z-axis is assumed, otherwise at least 22 measurements are required when common z-axis is not assumed.

Measured gyroscope angular rates is assumed to follow the model shown below: 

     Ωmeas = bg + (I + Mg) * Ωtrue + Gg * ftrue + w
Where: - Ωmeas is the measured gyroscope angular rates. This is a 3x1 vector. - bg is the gyroscope bias. Ideally, on a perfect gyroscope, this should be a 3x1 zero vector. - I is the 3x3 identity matrix. - Mg is the 3x3 matrix containing cross-couplings and scaling factors. Ideally, on a perfect gyroscope, this should be a 3x3 zero matrix. - Ωtrue is ground-truth gyroscope angular rates. - Gg is the G-dependent cross biases introduced by the specific forces sensed by the accelerometer. Ideally, on a perfect gyroscope, this should be a 3x3 zero matrix. - ftrue is ground-truth specific force. This is a 3x1 vector. - w is measurement noise. This is a 3x1 vector.

    • estimatedMg

      private com.irurueta.algebra.Matrix estimatedMg
      Estimated gyroscope scale factors and cross coupling errors. This is the product of matrix Tg containing cross coupling errors and Kg containing scaling factors. So that: 
           Mg = [sx    mxy  mxz] = Tg*Kg
          [myx   sy   myz]
          [mzx   mzy  sz ]
      Where: 
           Kg = [sx 0   0 ]
          [0  sy  0 ]
          [0  0   sz]
      and 
           Tg = [1          -alphaXy    alphaXz ]
          [alphaYx    1           -alphaYz]
          [-alphaZx   alphaZy     1       ]
      Hence: 
           Mg = [sx    mxy  mxz] = Tg*Kg =  [sx             -sy * alphaXy   sz * alphaXz ]
          [myx   sy   myz]            [sx * alphaYx   sy              -sz * alphaYz]
          [mzx   mzy  sz ]            [-sx * alphaZx  sy * alphaZy    sz           ]
      This instance allows any 3x3 matrix however, typically alphaYx, alphaZx and alphaZy are considered to be zero if the gyroscope z-axis is assumed to be the same as the body z-axis. When this is assumed, myx = mzx = mzy = 0 and the Mg matrix becomes upper diagonal: 
           Mg = [sx    mxy  mxz]
          [0     sy   myz]
          [0     0    sz ]
      Values of this matrix are unit-less.

      Hence: 
           Mg = [sx    mxy  mxz] = Tg*Kg =  [sx             -sy * alphaXy   sz * alphaXz ]
          [myx   sy   myz]            [sx * alphaYx   sy              -sz * alphaYz]
          [mzx   mzy  sz ]            [-sx * alphaZx  sy * alphaZy    sz           ]
      This instance allows any 3x3 matrix however, typically alphaYx, alphaZx and alphaZy are considered to be zero if the gyroscope z-axis is assumed to be the same as the body z-axis. When this is assumed, myx = mzx = mzy = 0 and the Mg matrix becomes upper diagonal: 
           Mg = [sx    mxy  mxz]
          [0     sy   myz]
          [0     0    sz ]
      Values of this matrix are unit-less.

      private double evaluate(double bx, double by, double bz, double m11, double m21, double m31, double m12, double m22, double m32, double m13, double m23, double m33) throws com.irurueta.numerical.EvaluationException
      Computes estimated true angular rate squared norm using current measured angular rate and provided parameters. This method is internally executed during gradient estimation and Levenberg-Marquardt fitting needed for calibration computation.
      Parameters:
      bx - x-coordinate of bias.
      by - y-coordinate of bias.
      bz - z-coordinate of bias.
