Claim 13:
14. An infrared (IR) imaging system comprising:
at least two spatially and spectrally different optical channels;
a plurality of cameras;
a reference having an unknown temperature; and
a data-processing unit comprising a processor, the IR imaging system configured to:
acquire, with the plurality of cameras, a plurality of image frames of an object, one or more of the plurality of image frames having regions with the unknown temperature that corresponds to the reference;
calculate a dynamic calibration correction using a temperature measured by one of the plurality of cameras based on the one or more of the plurality of image frames having regions with the unknown temperature as a reference temperature; and
apply a calibration correction to the other cameras in the plurality of cameras to match temperature estimates by the other cameras in the plurality of cameras with the reference temperature.
