Hello.
I am using a Flir E8 thermal camera and I want to read the measured temperature values in Matlab. I have already accomplished to see the thermal image in the Image Aquisition Box by using the winvideo adapter. Furthermore i can read some kind of raw 14-Bit data from the camera but i don't know how to convert this data back to temperature values.
Do you have any idea?

It seems like the second video stream you can acquire is the raw data video stream discussed in the following thread: https://www.eevblog.com/forum/thermal-imaging/flir-ex-realtime-raw-radiometric-data-streaming-via-uvc/
As shown there, it is not even "receivable" by every USB video class driver, so it's interesting that the winvideo adapter does.
More details regarding how the raw data can be transformed into temperature data can be found in this message, in particular the attached excel file shows the necessary formula: https://www.eevblog.com/forum/thermal-imaging/flir-ex-realtime-raw-radiometric-data-streaming-via-uvc/msg744673/#msg744673
