Frame correction

[metanav]

I am using a Lepton 3.1R radiometric 160x120 pixels camera. The documentation says:

"For the most accurate results, you should monitor ambient conditions throughout your data capture process and correct each frame individually with the conditions at the time it was captured."

I could not find any library code that does it. Can you please point me to the relevant methods or any suggestions if I need to implement it myself?

I have a setup that captures temperature, humidity, and object distance with each frame.

The relevant code is here: https://github.com/LJMUAstroecology/flirpy/blob/main/src/flirpy/util/raw.py

You'll need the various calibration coefficients for your camera.

The main environmental parameter that matters is the sensor temperature, but that's normally accounted for during preprocessing (if you're reading out TLinear data or similar). There are obvious things you can check like the emissivity of your surface, but unless you're in an unusually wet or dry environment, the atmosphere shouldn't change things very much.
