What are the zoom levels of the H20 Series?

23× hybrid optical zoom, 200× max zoom

What is the minimum focusing distance of the visible cameras of the Zenmuse H20 Series payloads?

The higher the zoom factor, the longer the focusing distance.

1×-2.8×, the minimum focusing distance is 1 m.

2.9×-3.9×, the minimum focusing distance is 2 m.

4×-4.6×, the minimum focusing distance is 3 m.

4.7×-14.2×, the minimum focusing distance is 5 m.

14.3×-200×, the minimum focusing distance is 8 m.

If the object is within the minimum focusing distance, the camera will not be able to focus. For example, if the aircraft/payload is 5 m away from a pylon, the camera will not be able to focus at a zoom level greater than 14.2×.

What factors affect the accuracy of the laser rangefinder?

Laser rangefinders measure distance using the time of flight of light. Its accuracy may be affected in environments where this time is affected. The range will be reduced in situations with smoke, rain, snow, dust or other environmental elements, and the values obtained may be incorrect.

When measuring an object with glass or transparent components:

If the glass is at a moderate distance, the distance to it can be measured (but not to the object behind the glass). It is possible that the glass may reflect the laser to another location, giving an incorrect result. If the glass surface is very smooth or very close, the light will pass through it and detect the object behind it, but the range will be greatly reduced.

At what frame rate does the Zenmuse H20T thermal camera record?

30 fps

How accurate is the thermal measurement of the Zenmuse H20T?

Accuracy is ±2 °C or ±2 % (whichever is greater). (Measured at 25 °C in a windless laboratory at a distance of 5 m from a black body).

Note: Black bodies have different emissivity levels, the above measurement is based on a particular black body and should only be used for reference.

What factors affect the temperature measurement accuracy of the Zenmuse H20T?

The reflectivity of the objects: shiny metals have a higher reflectivity and will result in lower accuracy, giving lower temperatures than the real ones.

The temperature of the background radiation: on a sunny day with a clear sky the accuracy will be affected to a lesser extent than on a cloudy day.

Ambient temperature and humidity: the higher the temperature and humidity, the more likely it is that the measurement will be affected and the accuracy will drop.

The distance between the camera and the object: the farther away the object is from the camera, the lower the accuracy.

What is the difference between the high and low gain modes in the thermal camera of the Zenmuse H20T?

High gain mode: measures a smaller temperature range but with higher accuracy. The temperature range is -40 to 150 °C.

Low gain mode: measures a larger temperature range, but with lower accuracy. The temperature range is -40 to 550 °C.

Can the Zenmuse H20T thermal camera be digitally zoomed?

Yes, it has two, four and eight times digital zoom.

What is the Zenmuse H20T flat field calibration or FFC?

Flat field calibration is used to optimize thermal image quality and to make temperature changes more easily visible. You can disable the automatic FFC in the settings to activate it manually.

What different ways are there to measure temperature using a Zenmuse H20T?

There are two forms: Spot Meter measures the temperature of a single point, and Area Measurement measures the different temperatures occurring within an area.

Are different versions of the Zenmuse H20T available with different focal lengths, what is the focal length of your thermal camera?

The Zenmuse H20T has only one model. Its thermal camera has a focal length of 13.5 mm (f1.0). It is a distance equivalent in 35 mm to 58 mm. The diagonal field of view is 40.6°.

What software can I use to process thermal images taken with the Zenmuse H20T?

You can process them with the DJI Thermal Analysis Tool. Download it here: https://www.dji.com/es/zenmuse-h20-series/downloads

What can I do if the lens fogs up?

The Zenmuse H20 series is designed to prevent water damage to its components. However, if the humidity is too high or if the instrument is exposed to rain, water vapor may enter the chamber. When turned on, the electrical components will heat up and cause any moisture that has entered to evaporate, eventually condensing on contact with the lens, resulting in fogging. This can usually be solved by turning on the aircraft and waiting for the vapor to dissipate. If you are not using the instrument, we recommend that you store it in a designated case or in a cool, dry place with a relative humidity of less than 40%.

What is Night Scene mode?

In Night Scene mode, the camera will change the infrared filter and optimize the ISP settings for low light conditions.

What is High-Res Grid Photo Mode?

In DJI Pilot, you can select an area in the wide-angle view and a wide-angle image will be taken while the stabilizer automatically rotates and captures a series of photos at 20 MP of the indicated area at the currently selected zoom level. All captured images will be saved in a subdirectory on the SD card, generating an HTML file that can be opened with a web browser to view the overall image and detailed close-ups.

What is the maximum capacity of the microSD card?

128 GB. We recommend using a UHS-I microSD card with a speed grade 3.

What applications are supported?

At this time, the Zenmuse H20 series is only compatible with the Android version of DJI Pilot.

Can photos and videos be captured at the same time?

Yes. This requires a firmware update.

Is it possible to take pictures with countdown?

Yes. This requires a firmware update.

What drone platforms are they compatible with?

With the Matrice 300 RTK. Upgrades both the aircraft and the remote control.

On which stabilizer connector can they be mounted?

Both versions can be mounted on any of the M300 RTK connectors.

How do I update the Zenmuse H20 series firmware?

Before upgrading, make sure that the aircraft is powered off, the instrument is properly mounted on the aircraft, the microSD card has sufficient storage space, and the Intelligent Flight Battery has sufficient power supply. Visit the official DJI website and go to the download section of the Zenmuse H20 product page. Download the latest firmware package.

Save the downloaded firmware package to the root directory of the microSD card. Insert the microSD card into the microSD card slot of the instrument. Turn on the aircraft and the stabilizer will perform a self-test process. Turn on the aircraft and the stabilizer will perform a self-test process.
