Troubleshooting • Re: Using pi 5 with usb thermal camera

Finally figured out the reason why this happens! There is small noises on the frame which contain 0 value so this is the reason why the minimum range of temperature is too low like -273.15. My workaround is simple just replacing that 0 values to normal value. For instance i'm targeting the minimum temperature is 20 so replacing 0 to 29315. You can use this formula to convert Celsius to Kelvin `val * 100 + 27315`.

I still don't know where that noises come from but until this bug resolved we can use this workaround.
I'm attaching the complete workaround here. Hope it would help someone.
