Hello people,
over the past months I've written a driver for the Guide MobIR Air¹
USB-C thermal camera. The driver uses v4l2loopback and runs in user
space with python.² The driver manages camera state, calibration and
conversion of the raw microbolometer to temperature values.
In my research I couldn't find any mentions of a thermal camera support
in the Linux kernel nor the media subsystem, so I assume I'm the first
to ask here and we would presumably need lay out some ground work.
The current camera driver outputs the temperature in the Y16 format as
Kelvin * 100 (i.e. 28056 (raw) -> 280.56K -> 7.41°C). This allows for
further processing down the line with i.e. OpenCV, but has its
limitations. Especially as temps of only up to 382.2°C can be displayed
currently.
Does it seem feasible to integrate support for thermal cameras in the
Linux kernel and more specifically in the v4l2 subsystem?
