Class Documentation

class MagnetometerCalibrationEllipse2d : public navtk::magnetic::MagnetometerCalibrationScaleFactorBias 

Class for calibrating magnetometer measurements using the Ellipse2D method.

This method is taken from Section 2.4.5.1 of Shockley PhD Dissertation: Ground Vehicle Navigation Using Magnetic Field Variation, 2012 (available on dtic.mil)

Public Functions

MagnetometerCalibrationEllipse2d(bool calibrate_caruso = false)

Constructor.

Parameters: calibrate_caruso – if true, compute calibration parameters with the 2D Caruso method first, then further calibrate with the Ellipse2D method.

virtual void generate_calibration(const Matrix &mag) override

Given x and y magnetometer values, compute the calibration parameters using the Ellipse2D method.

Parameters: mag – Matrix of magnetometer measurements(any units), with each row corresponding to an axis, and each column to a measurement. Must have 2 rows, with the first being the x-axis, and the second being the y-axis.
