Introduction
The ZENMUSETM XT 2 gimbal and camera features a FLIR longwave infrared thermal camera and
a visual camera, providing both infrared and visible light imaging simultaneously. The HeatTrack
and QuickTrack features make it easy to mark and track objects on your mobile device’s screen.
The FLIR longwave infrared thermal camera provides high-sensitivity (<50 mK @nf/1.0) infrared
scanning at 640/30 fps or 336/60 fps (depending on the camera model), and has 9 mm, 13 mm,
19 mm, and 25 mm lens options. The visual camera captures 4K videos and 12MP photos.
As with other DJITM 3-axis gimbal systems, the Zenmuse XT 2 can be mounted onto the
MATRICETM 200 series and Matrice 600 series aircraft and can stream live HD video to the
DJI Pilot app. This makes it excellent for aerial thermal applications such as inspection and
maintenance, search and rescue, and precision agriculture.

ZENMUSE XT 2 User Manual
1. Spotlight
Spotlight provides access to the QuickTrack and HeatTrack features. When using QuickTrack,
drag a box on the screen surrounding the desired subject, which the gimbal will follow. The red
and blue points represent the hottest and coolest points in the selected area, respectively. If the
desired subject is lost during tracking, manually reselect it.
When using HeatTrack, the gimbal automatically recognizes and follows the hottest object on
the screen. The red point represents the hottest point on the screen. If the gimbal recognizes a
hotter point while tracking, the red point will move and a circle will appear around it. Tap on this
point to follow it.
Please note that Spotlight is only available when using the Zenmuse XT 2 with the M200 series
aircraft.
2. Gimbal Mode
The three gimbal modes are Follow, Free, and Recenter.
3. FFC Calibration

Infrared mode
Only displays the footage that infrared thermal camera captures.
MSX mode
Fuses the infrared and visual footage. Tap the tool icon to select the degree of fusion.
Spot Meter and Area
Measurement Button
Fusion Degree Settings
Spot meter and Area measurement are available when using Infrared or MSX modes.
Spot Meter
The temperature of any position in an image can be measured with an accuracy of ±10°C
(±50°F). Under ideal environmental conditions are ideal, the camera provides an accuracy of
±5°C (±41°F).
Area Measurement
Enabling this function will display the average temperature, lowest temperature, highest
temperature, and the corresponding locations of each area in DJI Pilot. Full-screen view also
supported.
The temperature measurement accuracy is affected by various factors:
1) Reectivity of objects - shiny metals with high reectivity will reect 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 - a sunny day without clouds will have less of an effect
on the accuracy than a cloudy day.
3) Air temperature and humidity - as temperature and humidity increases, accuracy decreases.
4) Distance between camera and object - as distance decreases, accuracy increases.
5) Emissivity of objects – emissivity and accuracy increase together.
When MSX is selected, adjust the accuracy of the MSX footage using MSX adjustment.

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.

ZENMUSE XT 2 User Manual
Scene
Instantly enhance your images through selecting the Linear, Default, Sea/Sky, Outdoor, Indoor,
Manual, or Custom options. The camera will automatically apply the following properties to obtain
the best result.
DDE (Digital Detail Enhancement): Enhances image details and/or suppresses xed pattern
noise.
ACE (Active Contrast Enhancement): Provides a contrast adjustment dependent on the relative
scene temperature. ACE thresholds greater than 0 impart more contrast to hotter scene content
and decrease contrast for colder scene content (e.g., the sky or ocean). ACE thresholds less
than 0 do the opposite by decreasing contrast for hotter scene content and leaves more of the
gray-scale shades available to represent the colder scene content.
SSO (Smart Scene Optimization): Denes the percentage of the histogram that will be allotted
a linear mapping. SSO features facilitate the avoidance of irradiance level compression, which
is specically important for bimodal scenes, and better preserves the radiometric aspects of
an image (i.e., the difference in gray shades between two objects is a better representative
of the difference in temperature). While radiometry is better preserved with this feature, the
optimization of local contrast is compromised.
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.
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 measured in a single color scheme impart higher contrast and better visibility.
Individual isotherms (or color schemes) are separated by upper, middle, and lower thresholds,
which have a value in percentage or temperature.
Take the white-hot isotherm as an example. In the image below, the lower threshold of 128-grayscale
is used to represent temperature differences.
Between the lower and middle thresholds, color scheme 1 (48-Isotherm) is used. Between the
middle and upper thresholds, color scheme 2 (48-Isotherm) is used. Above the upper threshold,
color scheme 3 (32-Isotherm) is used.
