Image captured by PureThermal 2 - FLIR Lepton

[Varat7v2]

I captured image from Pure Thermal - FLIR Lepton camera, but its not working with FlirImageExtractor. Its throwing the following error: KeyError: 'RawThermalImageType' And when I run exiftool , lots of meta-data are missing? How should I do to capture image with full image meta-data details? Any kind of suggestions / references will be helpful to me.

When I run exiftool <on-my-image>, its just showing the following data:

ExifTool Version Number : 10.80 File Name : my_photo-1.jpg Directory : .

Thank you!

I have the same issue. Did you manage to solve it?

@Mohit-Ak I am using FLIR Lepton 2. This camera does not have radiometry. So I have to try with other way - using directly 14 bit raw data and calibrating it to approximate temperature. FlirImageExtractor did not work for me because of my lower functional camera. It depends on which camera you are using.
