Geographic Information Systems Asked by Reisenrich on June 30, 2021
I am trying to import Thermal data from a FLIR Zenmuse xt radiometric lens thermal camera.
Flir does not include a conversion with the camera and does not respond to my emails regarding the conversion.
On the Pix4D website they include the conversion for the camera which is
“0.04 * [Thermal Image] – 273.15”
This equation works for the most part but some images can be as much as 30 degrees F off.
Currently working in QGIS to apply the Pix4D conversion using raster calculator.
I have attached the TIFF as well as the .RJPEG for viewing in Flir tools.
Please let me know if you have any questions or if there is anything else I need to add.
The general temperature range I am looking for is 32.8-106.6 F
Thermal images can be found here

I've just tryed the images you post with the adjusted index from Pix4D on the raster calculator of QGIS. It gives me good results, then I've tryed out the JPEG Image on Flir Tools and you can match the results from the JPEG to those on the TIFF by adjusting the emissivity values and T reflect.
