Claim Text:
1. A method comprising: rotating a thermal imaging camera in a plurality of physical orientations in a three-dimensional space during a calibration routine; receiving a plurality of measurements from a magnetic sensor mounted in the thermal imaging camera as the thermal imaging camera is rotated in the three-dimensional space during the calibration routine, each of the plurality of measurements being representative of three orthogonal components of a magnetic field when the thermal imaging camera is in a given orientation; generating a plurality of data points from the plurality of measurements, each of the plurality of data points corresponding to one of the plurality of measurements representative of the three orthogonal components of the magnetic field; and displaying on a display associated with the thermal imaging camera a simulated three-dimensional plot of the data points, wherein the simulated three-dimensional plot is updated in substantially real-time during the calibration routine as new data points are generated as a physical orientation of the thermal imaging camera changes.
