If you have a radiometric sensor you should exploit this feature and no calibration is required.
You can read more in chapter 3.5.1 of the datasheet:
500-0659-00-09 Rev204 Lepton Engineering Datasheet.pdf
My driver does not support it because I have a Lepton 3.0 that has no radiometry, but I suppose that you can easily modify it.

You must modify this function to be sure that you are using the
TLinearfeature: https://github.com/Myzhar/Lepton3_Jetson/blob/master/grabber_lib/src/Lepton3.cpp#L777-L805I could do that if I have a Lepton 3.5, but it's too expensive for me now.
