public class KnownBiasAndFrameGyroscopeNonLinearLeastSquaresCalibrator extends Object implements KnownBiasAndFrameGyroscopeCalibrator<StandardDeviationFrameBodyKinematics,KnownBiasAndFrameGyroscopeNonLinearLeastSquaresCalibratorListener>, GyroscopeNonLinearCalibrator, UnorderedStandardDeviationFrameBodyKinematicsGyroscopeCalibrator
Estimates gyroscope 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 uses an iterative approach to find a minimum least squared error solution.

To use this calibrator at least 6 measurements at different known frames must be provided. In other words, accelerometer and gyroscope (i.e. body kinematics) samples must be obtained at 6 different positions, orientations and velocities (although typically velocities are always zero).

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.

    • measurements

      private Collection<StandardDeviationFrameBodyKinematics> measurements
      Contains a collections of body kinematics measurements taken at different frames (positions, orientations and velocities) and containing the standard deviations of accelerometer and gyroscope measurements. If a single device IMU needs to be calibrated, typically all measurements are taken at the same position, with zero velocity and multiple orientations. However, if we just want to calibrate a given IMU model (e.g. obtain an average and less precise calibration for the IMU of a given phone model), we could take measurements collected throughout the planet at multiple positions while the phone remains static (e.g. while charging), hence each measurement position will change, velocity will remain zero and orientation will be typically constant at horizontal orientation while the phone remains on a flat surface.

    • commonAxisUsed

      private boolean commonAxisUsed
      This flag indicates whether z-axis is assumed to be common for accelerometer and gyroscope. When enabled, this eliminates 3 variables from Ma matrix.

      Known z coordinate of gyroscope bias expressed in radians per second (rad/s).

    • 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.

    • estimatedGg

    • estimatedReducedChiSq

      private double estimatedReducedChiSq
      Estimated reduced chi square value. This is equal to estimated chi square value divided by its degrees of freedom. Ideally this value should be close to 1.0.

    • estimatedMse

      private double estimatedMse
      Estimated mean square error respect to provided measurements.

    • estimatedP

      private double estimatedP
      Estimated probability of finding a smaller chi square value expressed as a value between 0.0 and 1.0. The smaller the found chi square value is, the better the fit of the estimated parameters to the actual parameter. Thus, the smaller the chance of finding a smaller chi square value, then the better the estimated fit is.

    • estimatedQ

      private double estimatedQ
      Estimated measure of quality of estimated fit as a value between 0.0 and 1.0. The larger the quality value is, the better the fit that has been estimated.

    • getEstimatedMg

      public com.irurueta.algebra.Matrix getEstimatedMg()
      Gets 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.

      estimated gyroscope scale factors and cross coupling errors.
