Since I needed the raw data for some science, I built a quick parser for the "IRG" file format Infiray's C200 series thermal cameras write their radiometric data in. The files basically contain a low-res preview and the original, full-resolution thermal data next to a JPEG with the visual camera's image.
In case you were wondering, this is what a tray of cookies looks like on a thermal camera, fresh out of the oven (first pic) and during cooling (the other pics). The second pic shows traditional German cinnamon waffles, the others show shortcrust cookies.
The applications of thermal cameras in the kitchen are totally underrated. You can easily tell which ones are cold enough to be stacked and put into boxes.
Temperatures shown in the pictures are in Celsius.
In case you wondered, this is what the first stages of a German-style Bolognese sauce looks like in a thermal camera. Pic#1 shows 2tbsp of olive oil in the pot. What's awesome is that you can see clearly defined convection cells despite it being only an ~1mm layer. Pic#2 shows it after adding the minced meat, and pic#3 shows it after deglazing with red wine. You can clearly make out the boiling points of water and ethanol in those two.
