A tool to convert DJI thermal images to plain 32bit float TIFFs for use with WebODM.

• Download and install https://github.com/uav4geo/Thermal-Tools/releases/download/v1.2.0/Thermal_Tools_Setup.exe

• Download https://github.com/uav4geo/Thermal-Tools/releases/download/v1.2.0/Thermal_Tools.AppImage
• Run: chmod +x ./Thermal_Tools.AppImage && ./Thermal_Tools.AppImage

Afterwards:

• Select a folder with thermal images captured with a DJI drone
• Optionally set environment parameters
• Press "Process"

⚠️ When processing the resulting images with WebODM, make sure you don't select the radiometric-calibration option. The images processed with this software are already calibrated.

The application can be invoked from the command line for processing images in scripts:

./Thermal_Tools.AppImage [args]

--input                    Input folder for batch processing. Default: ""
--output                   Output folder for batch processing. Default: "converted"
--distance                 Distance (m). Default: 5
--humidity                 Humidity (%). Default: 70
--emissivity               Emissivity. Default: 1.0
--ambient-temperature      Ambient Temperature (degrees C). Default: 25.0
--reflected-temperature    Reflected Temperature (degrees C). Default: 23.0

You can also process thermal images remotely via a web API with NodeThermalTools.

Unfortunately DJI does not provide binaries for macOS, so this application cannot work on macOS.

You'll need to install https://docs.flutter.dev/get-started/install, then:

flutter build windows

Or

flutter build linux

Install FVM and run:

fvm flutter pub get

You can run the application in development mode by running:

fvm flutter run
