image in the Thermal Analysis Screen. The Thermal Analysis Screen contains the
Toolbar, Image Display Area, Topbar, Chroma Bar, Information Display Area and
Action Bar.
Toolbar
The toolbar on the left contains the following tools:
- Select : Once in the Thermal Analysis Screen, the Select tool is enabled by default. Use the mouse scroll wheel to zoom in or out on the image. Click and drag to view different areas of the image. After switching to a different tool, click the icon again or press the shortcut key (Esc key/number key 1) to switch back to the Select tool.
- Spot Temperature : Click the icon or press the shortcut key (number key 2) to select the tool, and then left-click the point that needs to be measured in the image and the temperature of that point will be shown. Drag the point to change the location of the measurement. Right-click the point to delete the point, select the font size, or where to show the annotations.
- Rectangle Temperature: Click the icon or press the shortcut key (number key 3) to select the tool, and then left-click and drag to create a rectangular measurement area. The highest, lowest, and average temperatures of the rectangular area will be shown on the screen. Left-click the rectangle to change its size and location.

- Fit Window: Click the icon to adjust the image display size to fit the window. Palette Color Description The supported devices offer a variety of palette options. Distinct colors are used to show temperature differences in the thermal image, which are related to grayscale intensity. The temperature range of the image is mapped to 256 colors and displayed in an 8-bit JPEG image. The following table shows all palette options.
- Palette Color Description
- The supported devices offer a variety of palette options. Distinct colors are used to
show temperature differences in the thermal image, which are related to grayscale
intensity. The temperature range of the image is mapped to 256 colors and displayed
in an 8-bit JPEG image. The following table shows all palette options
| Palette | Description |
|---|
White Hot
| The most commonly used pseudo color, using white for high temperatures and black for low temperatures, which is a natural association for people.
Fulgurite
| Dark red represents low temperatures and white represents high temperatures. The warm tone of this palette aligns with people’s association with hot temperatures.
Iron Red
| This palette displays nuanced differences in heat signatures, quickly displaying anomalies and human bodies. Hotter objects appear as light warm colors and colder objects appear as dark cool colors.
Hot Iron
| Red represents high temperatures, and cool colors represent low temperatures. It is able to identify hot targets quickly, while showing the details of cool targets.
Medical
| This palette shows nuanced differences in temperatures, and is therefore
ideal for scenarios with small temperature changes. In environments with low
contrast, it is still able to detect objects and slight temperature changes.
It is mainly used in the medical field for human body temperatures.
---|---
Arctic| Uses the same palette as Medical, except switching the purple for a
cool blue to better reflect temperature changes.
Rainbow 1
| Similar to Medical, it reduces the warm color ratio and increases the cold color ratio for high temperature targets to better show the details of cool targets.
Rainbow 2
| The color transition is reduced, the warm and cold colors are moderately proportioned, which can show the details of high and low temperature targets at the same time.
Tint
| Uses black and white for low temperatures and bright red for high temperatures, it is able to detect high temperature targets quickly. Mainly used for high-contrast environments, ideal for quickly and accurately identifying high temperature targets at night.
Black Hot
| The opposite to White Hot, using black for warmer objects and white for cooler objects. The heat distribution of high temperature targets can be better observed when outdoors.
Different palettes applied to the same example image are shown below.

Parameters
- Distance : The distance to the target. An infrared thermal imager generates thermal images by receiving infrared radiation from objects. The farther away the object, the more the radiation attenuates. The camera’s default calibration distance is generally fixed during production. This is the distance at which temperature measurements are the most accurate. Being too close or too far will result in bigger measurement errors. Relative Humidity: the relative humidity of the environment. Please configure this parameter based on the actual environmental conditions.The default value 70 means that the relative humidity is 70%, and the value range is [20~100]. Humidity configurations could affect the measurement result, but the effect is limited.
- Emissivity: how strongly the target surface is emitting energy as thermal radiation. Refer to the Emissivity of Common Materials Table to configure, since the target surface may be corroded or oxidized, the actual emissivity value may differ from the reference value. Emissivity configurations could significantly impact the measurement result.
- Reflected Temperature: the surface of the target that is measured could reflect the energy radiated by the surrounding objects. This reflected energy could be picked up by the camera along with the radiation, which could cause an error in the temperature reading. If there are no objects with extremely high or low temperatures nearby, set this parameter as the ambient temperature. Reflected temperature configurations could affect the measurement result, and the bigger the difference between the reading and the ambient temperature, the bigger the impact.
- Ambient Temperature: Refers to the air temperature between the infrared thermal camera and the target surface. It needs to be set based on the environment’s actual temperature. When capturing infrared images, the customized or auto-set ambient temperature will be saved. The auto-set ambient temperature is the temperature detected by the temperature sensor attached to the camera. Currently, users can only set ambient temperature for images captured by Zenmuse H30T, and the measurement range is from -40° to 80°C (-40° to 176° F). Press the Enter key or click anywhere outside the input field to finish setting the parameters.
If the input value is beyond the range, the software will input the threshold value instead.

- Export: Click Export to go to the Report screen. Click Export PDF or Export DOC to export a PDF or DOC report for the selected thermal image, which contains the measurements, parameters settings, image information, annotations, and remarks.Users can also customize the logo and header for the report. Click Export Image toexport a JPG image which contains measurements and the chroma bar information.
- Save: Save data such as spots and areas of temperature measurement, or specific palette settings to the R-JPEG images. This information is only visible when using the DJI Thermal Analysis Tool 3. This data cannot be seen when viewing these images inanother software.
Saving an image will overwrite the original image, please make a backup if needed.
