Introduction
The Zenmuse XT gimbal and camera features the FLIR Longwave Infrared Thermal Camera. It
provides high-sensitivity (<50 mK@f/1.0) infrared imaging at 640/30 fps or 336/60 fps depending on
the camera model, and comes with 6.8 mm, 7.5 mm, 9 mm, 13 mm or 19 mm lens options.
As with other DJI 3-axis gimbal systems, the Zenmuse XT can be mounted on the Matrice 100 or
Inspire 1 series aircraft and stream live video to the DJI GO app. This makes it excellent for aerial
thermal applications such as inspection and maintenance, search and rescue, and precision
agriculture.

The mounted Zenmuse XT should look like this.
Ensure the Zenmuse XT is mounted securely.
The Zenmuse XT is a delicate instrument. Do not disassemble the gimbal or camera as
this will cause permanent damage.
DJI GO App
Downloading DJI GO
Search for ‘DJI GO’ on the App Store or Google Play and download the app to your mobile device.
DJI GO supports iOS 8.0 (or later) or Android 4.1.2 (or later).
Connecting to DJI GO
1. Turn on the aircraft and the remote controller.
2. Connect your mobile device to the remote controller using a USB cable.

2. General Settings
ROI (Region of Interest)
Use this feature to manage color range distribution across the screen to maximize contrast for
regions of highest interest.
If you want the color spectrum to be evenly distributed across the entire image, select "Full".
If there is large patch of sky (relatively low temperature) in your image, much of the color
spectrum will be allocated to the lower range, meaning other parts of the spectrum will have less
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.
Palette
The Zenmuse XT offers a variety of Palette options. Distinct colors are used to show temperature
differences in the thermal image, which are related to the grayscale intensity. The temperature
range of the image is mapped to 256 colors and displayed in the 8-bit JPEG or MPEG-4 format.

WhiteHotIso
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. sky or ocean). ACE thresholds less than 0 do
the opposite by decreasing contrast for hotter scene content and leaving more of the gray-scale
shades to represent the colder scene content.
SSO (Smart Scene Optimization) defines the percentage of the histogram that will be allotted
a linear mapping. SSO features facilitate the avoidance of irradiance level compression, which
is specifically important for bi-modal scenes, and better preserves the radiometric aspects of
an image (i.e. the difference in gray shades between two objects is more representative of the
difference in temperature). While radiometry is better preserved with this feature, the compromise
is the optimization of local contrast.
Contrast: the ratio of the black and white of the image. The colors will be richer and have more
contrast when the value is large.
Brightness: The brightness of the image.
Isotherm
Enabling Isotherm 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. Below the lower threshold, 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.

Spot Meter
The Zenmuse XT can measure the average temperature of the 4×4 pixels in the center of an image
with an accuracy of ±20˚C in High Gain mode, and an accuracy of 20% of the entire temperature
range or 20˚C (whichever is greater) in Low Gain mode.
The spot meter’s 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 a larger error; 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 - the higher the temperature and humidity, the lower the accuracy.
4) Distance between camera and object - the shorter the distance, the higher the accuracy.
5) Emissivity of objects - the higher the emissivity, the higher the accuracy.
Gain Modes
High Gain Mode: The camera covers a smaller temperature range but is more sensitive to
temperature differences.
Low Gain Mode: The camera covers a wider temperature range but is less sensitive to temperature
differences.
Auto Gain Mode (Default): The camera will automatically select the optimal gain mode according to
the temperature range of the image.

The calibration happens automatically and is used to optimize image quality. A blue square in the
upper right corner of the screen indicates that the FFC calibration is about to begin. During the
calibration, your screen may freeze momentarily and the camera will make a clicking sound.
