public abstract class RobustKnownMagneticFluxDensityNormMagnetometerCalibrator extends Object implements MagnetometerNonLinearCalibrator, UnknownHardIronNonLinearMagnetometerCalibrator, OrderedStandardDeviationBodyMagneticFluxDensityMagnetometerCalibrator, QualityScoredMagnetometerCalibrator
This is an abstract class to robustly estimate magnetometer hard-iron biases, cross couplings and scaling factors.

To use this calibrator at least 10 measurements taken at a single unknown position and instant must be taken at 10 different unknown orientations when common z-axis is assumed, otherwise at least 13 measurements are required.

Measured magnetic flux density is assumed to follow the model shown below: 

     mBmeas = bm + (I + Mm) * mBtrue + w
Where: - mBmeas is the measured magnetic flux density. This is a 3x1 vector. - bm is magnetometer hard-iron bias. Ideally, on a perfect magnetometer, this should be a 3x1 zero vector. - I is the 3x3 identity matrix. - Mm is the 3x3 soft-iron matrix containing cross-couplings and scaling factors. Ideally, on a perfect magnetometer, this should be a 3x3 zero matrix. - mBtrue is ground-truth magnetic flux density. This is a 3x1 vector. - w is measurement noise. This is a 3x1 vector. Notice that this calibrator assumes that all measurements are taken in a short span of time where Earth magnetic field can be assumed to be constant at provided location and instant.

    • commonAxisUsed

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

    • estimatedHardIron

      private double[] estimatedHardIron
      Estimated magnetometer hard-iron biases for each magnetometer axis expressed in Teslas (T).

    • estimatedMm

      private com.irurueta.algebra.Matrix estimatedMm
      Estimated magnetometer soft-iron matrix containing scale factors and cross coupling errors. This is the product of matrix Tm containing cross coupling errors and Km containing scaling factors. So tat: 
           Mm = [sx    mxy  mxz] = Tm*Km
          [myx   sy   myz]
          [mzx   mzy  sz ]
      Where: 
           Km = [sx 0   0 ]
          [0  sy  0 ]
          [0  0   sz]
      and 
           Tm = [1          -alphaXy    alphaXz ]
          [alphaYx    1           -alphaYz]
          [-alphaZx   alphaZy     1       ]
      Hence: 
           Mm = [sx    mxy  mxz] = Tm*Km =  [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 accelerometer z-axis is assumed to be the same as the body z-axis. When this is assumed, myx = mzx = mzy = 0 and the Mm matrix becomes upper diagonal: 
           Mm = [sx    mxy  mxz]
          [0     sy   myz]
          [0     0    sz ]
      Values of this matrix are unit-less.

    • estimatedP

      private double estimatedP

    • 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.

    • getEstimatedMm

      public com.irurueta.algebra.Matrix getEstimatedMm()
      Gets estimated magnetometer soft-iron matrix containing scale factors and cross coupling errors. This is the product of matrix Tm containing cross coupling errors and Km containing scaling factors. So tat: 
           Mm = [sx    mxy  mxz] = Tm*Km
          [myx   sy   myz]
          [mzx   mzy  sz ]
      Where: 
           Km = [sx 0   0 ]
          [0  sy  0 ]
          [0  0   sz]
      and 
           Tm = [1          -alphaXy    alphaXz ]
          [alphaYx    1           -alphaYz]
          [-alphaZx   alphaZy     1       ]
      Hence: 
           Mm = [sx    mxy  mxz] = Tm*Km =  [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 accelerometer z-axis is assumed to be the same as the body z-axis. When this is assumed, myx = mzx = mzy = 0 and the Mm matrix becomes upper diagonal: 
           Mm = [sx    mxy  mxz]
          [0     sy   myz]
          [0     0    sz ]
      Values of this matrix are unit-less.
