Hello Everyone,
I am having the same issue with quantitative measurement with XT2. I did couple of tests and compared results of measurements with handheld camera (Flir A65). The tests were both inside and outside of building . When both XT2 and handheld camera where inside the building they showed almost the same temperature. However, when I took them out to measure the surface temperature of a wall, XT2 showed very strange results like -6 degree which was completely unrealistic as the outside temperature was 6 degree above zero and the handheld camera showed the temperature +7 degree. We did the tests couple of times and looks like the XT2 is influenced by the ambient temperature and when the outside is cold the temperatures are way off. It is to be mentioned that these measurements were done without flying the drone (stationary).
Another tests also I did while we were running the drone and at that the temperature was even worse and the surface temperature measurements reduced dramatically during the flight (from -5 to -30). Again, the outside was 8 degree above zero and we were sure that the surface temperature should be above zero. Here, we found that it looks like the induced wind by the prop affects the measurement (cooling effect on the drone).
Generally, if anyone had the same issue please let me know as we don't know still the XT2 is not calibrated or there is some issue in detector of camera or any other possibilities.
Thanks
