Hi all,

So I got the Flir Lepton 3.5 with the PureThermal2 Breakout Board, and I'm able to access its video feed with python & opencv. Now, I would also like to access its radiometric data for each frame, and convert all the values in the frame into temperatures. However, I've been having a hard time finding resources to do this.

So, if anyone knows how to do this, or has links to resources that lay this out clearly, that would be greatly appreciated.

Thanks!

Sam
