So, I rented a FLIR thermal imaging camera for the weekend, for the serious purpose of checking the windows and overall insulation of our house.

But you can also take cat pictures with this thing.

@sunpig I got a cheap IR camera from AliExpress. It isn't the resolution of a Flir, but it's good enough.

@guigsy @sunpig looks like a Lepton sensor.

  • Since they are ≤9 fps / Hz and low-res they are are commonplace.
    • Some interpose it with a visible light camera's contrast detection to fake a higher resolution...

@kkarhan @sunpig yeah, the resolution isn't great. But it's ok. The Flir also cheats by overlaying an image from a visible light camera. Which is why it looks like it's captured so much texture. I've got the option to do that with my cheapo thermal camera, by blending with the phone camera's output, but as it has different optics on a big axis offset, the effect only works on more distant objects.

@guigsy @sunpig yeah, and with cheap sensors like the FLIR Lepton that's fine…

  • Tho if you ever had the privilegue to use a high-resolution, high-refresh-rate (if not highspeed) thermal camera, you kinda get addicted to it.
