Learn how to analyze the Radiometric Thermal images from your Zenmuse H20T or XTS camera. If you own a Matrice 300 drone, this is the software you will use to review your thermal imagery.
Since Radiometric Thermal images store the temperature data, this software can be used to easily report on your thermal images and quickly identify any abnormalities.
Radiometric thermal cameras have the ability to quantify and store the temperature data. While performance thermal cameras can only display the relative temperature differences. This is a key differential and should be a guiding factor when purchasing a thermal camera for industrial applications.

How to download:
Visit: https://www.dji.com/downloads/softwares/dji_dtat
Then select the exe link to download the software. Currently, this software only supports Windows.
Getting Started:
-
Set up your preferred unit of measurement (Farenheit, Celsius, Kelvin)
-
Import your image. Click the add icon, then select your R-JPEG file.
Here we have a thermal image of a roof with solar panels and a HVAC system. This thermograph was taken with the Zenmuse H20T with a DJI Matrice 300 RTK.
Radiometric thermal images are very flexible. Once you are viewing the thermal image in the analysis software you can change the image settings like pallet, emissivity, humidity, and reflected temperature.
When you import the thermal images into the Analysis tool it will display the raw image regardless of what color palette or measurement tools were used during the flight.
Keep in mind, certain elements of the thermograph, like focus, range, and distance from the subject can not be edited in the analysis software
-
Save any changes you have made to the image. These changes are only visible within the thermal analysis tool.
-
Resets the image to the original image in the White Hot palette.
-
Spot measurement This feature allows you to measure a single point in the image. Right-click to delete a spot measurement.
-
Area Measurement Measure the highest and lowest temperature of an area. Click and drag to create a box. This can be useful for finding the hottest/coldest point of an area or seeing the temperature delta in an area.
-
Palette View the image with various pseudo colors applied. Switching palettes changes the appearance of an image and highlights key areas without altering any of the temperature data.
-
Zoom in
-
Zoom out
-
Screenshot Save the current image to your computer for sharing reports.
-
Tune Use this slider to adjust the thermal span of the image. This allows you to adjust the color palette to highlight certain temperature ranges. This is important when the image features a wide temperature range but you want to report on a small anomaly within that range.
-
Parameter settings Increase the accuracy of temperature data by adjusting these settings. Emissivity is how strongly the target surface is emitting energy as thermal radiation. Emissivity values can significantly impact the accuracy of the temperature readings. Refer to the emissivity of the common materials table to determine the emissivity value of your subject.
-
Image Info Shows image information including model, serial number, focal length, aperture, image resolution, created or modified time, and file size.
