• **ROI (Region of Interest)***
  Use this feature to manage color range distribution across the screen to maximize contrast for regions of highest interest.

Select “Full” to evenly distribute the color spectrum across the entire image.
For instance, if there is a large patch of sky (relatively low temperature) in your image, much of the color spectrum will be allocated to the lower range, meaning that other parts of the spectrum will have a lower contrast. In this case, you may select “Sky excluded (33%)” or “Sky excluded (50%)” to ignore areas of the sky so that most of the spectrum can be allocated to remaining areas, providing higher contrast and utility for analysis.

• **Scene***
  Enhance your images instantly by selecting Default, Inspection, or Manual options. The camera will automatically apply the following properties to obtain the best result.

  • DDE (Digital Detail Enhancement): Enhances image details and/or suppresses fixed pattern noise.
  • Contrast: The ratio of the black and white of the image. Colors will be richer and have more contrast when the value is high.
  • Brightness: The brightness of the image.

• **Gain Mode***
  High Gain Mode: A narrower temperature range can be captured with a higher sensitivity to temperature differences.
  Low Gain Mode: A wider temperature range can be captured with a lower sensitivity to temperature difference.

• **Temperature Alert***
  After enabling the Area measurement feature, an alert temperature value can be set.
  When the highest temperature in the selected area exceeds the alert value, an onscreen notification will appear in DJI Pilot.

• **Auto FFC***

**Palette/Isotherm***
Palette
The Zenmuse H20T offers 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 the 8-bit JPEG or MP4 format.
The following table shows all palette options.

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.

Isotherm
This feature allows designated temperature ranges to be represented with different color schemes, so that objects within this range impart higher contrast and better visibility.
The temperature range is set by upper and lower thresholds.

**FFC Calibration***
Tap this button to execute FFC calibration, which is used to optimize image quality. During calibration, your screen may freeze momentarily and the camera will make a clicking sound.

**Zoom (Infrared thermal camera)***
Tap to adjust the digital zoom of the infrared thermal camera. 2x, 4x and 8x zoom options are supported.

**Display Mode***
Tap to switch between the IR and Split display modes for infrared thermal camera.
IR: only displays footage that the infrared thermal camera captures.
Split: Both the footage that the infrared thermal and the zoom camera captures will be displayed side by side.

Intelligent Functions

Click to Aim
Double-click the point of interest on the main screen, the gimbal will automatically move to the point of interest in the center of the screen.

High-Res Grid Photo
Drag to select an area in the wide camera view, the gimbal will move automatically and take a series of 20MP photos of the selected area at the current zoom ratio by the zoom camera.
Tap MENU > Photo Settings, and then select High-Res Grid Photo. After entering this function, the liveview will switch to the wide camera view. You can set the target shooting area by editing, moving and zooming the white grid on the screen.
All photos will be saved in the same sub-folder in the microSD card, and an HTML file will be created. To view the wide and close-up images, open this HTML file using a browser on a PC.

Night Scene
In Night Scene Mode, the camera will switch the IR filter of the zoom camera, which enabled shooting in low-light environment.
This function is only available for zoom camera, tap MENU > General Settings, and then enable the Night Scene.

Temperature Measurement

• Spot Meter
  The temperature of any position within the temperature measurement area on the screen can be measured.

• Area Measurement
  Drag an area within the temperature measurement area on the screen, the average temperature, lowest temperature, highest temperature, and the corresponding locations of this area will be displayed in DJI Pilot.

The temperature measurement accuracy is affected by various factors:

1. Reflectivity of objects – shiny metals with high reflectivity will reflect more of the background radiation and result in lower accuracy, whereas objects with matte surfaces will produce a higher accuracy.
2. Temperature of background radiation – sunlight has a great influence on the temperature measurement accuracy, direct or reflected sunlight should be avoided from the infrared thermal camera.
3. Air temperature and humidity – the temperature and humidity have been calibrated before delivery, but some temperature measurement errors are inevitable. Extreme temperatures or humidity levels will affect the measurement accuracy.
4. Distance between the camera and the object – the default distance used in calibration is 5 m, and the temperature measurement is most accurate at this distance. Deviations from this distance will lower the accuracy.
5. Emissivity of objects – the emissivity of the object will affect the temperature measurement accuracy. Generally, accuracy increases proportionally to emissivity. Emissivity is affected by factors such as the material, the roughness or the degree of oxidation of the object’s surface.

When measuring a blackbody 5 m away at a windless 25℃ indoors, the camera provides an accuracy of up to ±2℃ or ±2% (whichever is the larger value). Since the emissivity of different blackbody varies, this measurement result only represents the accuracy of the tested blackbody, for reference only.
