DJI Zenmuse XT vs DJI Zenmuse XT2 Thermal Cameras – For Drones

Thermal cameras have been used in various applications, and nowadays these are fitted to drones to show the aerial view of the scene. They are very helpful in the rescue operation, to identify gas or water leakage, in agriculture for scheduling irrigation, and to gain knowledge about plant physiology.

There are plenty of thermal imaging cameras available in the market, and it is essential to study and research to pick up the correct thermal camera for the drones. Initially, you should have a clear idea of your requirement. 

Here, we have reviewed and compared two popular thermal cameras Zenmuse XT and Zenmuse XT2 from the same company DJI. The main difference between these thermal cameras is, the Zenmuse XT is an infrared camera, but XT2 is a single device built-in with infrared as well as a visual camera. Further details of these two cameras are explained and differentiated below.

Technology 

XT – Image Enhancement software 

Optimization is the main principle in the infrared imaging process that provides maximum image definition and further helps in capturing the thermal data about the sight. FLIR provides image enhancement features including 

  • DDE (Digital Detail Enhancement)
  • SSO (Smart Scene Optimization) that enhances views in bimodal scenes.
  • ACE (Active Contrast Enhancement) that adjusts scene contrast with respect to temperature difference.
  • IBHEQ (Information-Based Histogram Equalization) compresses information of complex images to create images with clarity.

XT2 – MSX

Multi-Spectral Dynamic Imaging (MSX) from FLIR adds visible light details to thermal images and provides better clarity, embedding edge, and outline details. This onboard fusion process does not minimize the thermal transparency of the image like image fusing which combines visible light and thermal image.

Zenmuse XT2 with MSX technology has two cameras namely thermal camera and a visible light digital camera. While capturing the picture, both the thermal and digital camera works simultaneously and captures the picture in normal and thermal view.

Zenmuse XT2 has an inbuilt application that extracts outlines and other high-contrast edge details from the visible light images. Those details are superimposed to the thermal image. This makes the images in high definition and provides clear details of the view. 

MSX can be easily switched on or off when using a thermal imager. Even though Zenmuse XT has lots of image enhancement software developed by FLIR, the MSX software makes XT2 unique and beneficial.

Weatherproof

IP44 Weather proof in DJI Zenmuse XT2 Thermal Camera

DJI Zenmuse XT

Zenmuse XT does not have an IP rating which means it does not have water resisting capacity. It is recommended to use only in particular temperatures ranging from 14°F to 104°F (-10° to 40°C) and 5% to 95% of moisture conditions. And so it is capable of withstanding normal weather with a dry condition.

Zenmuse XT2

Zenmuse XT2 comes with an IP rating of 44 in which the first number 4 indicates the above-average level of protection from dust particles. The second number (4) of the IP rating indicates water resistance that protects the camera against spraying and dripping water. And therefore Zenmuse XT2 is the better choice in wet weather and rainy conditions. 

Compatible Drones

Fits easily to Matrice series

For DJI Zenmuse XT

Zenmuse XT thermal camera is a lower-end model, yet it is a versatile one that can be used for various purposes. This camera is compatible with many DJI drone models and can be mounted perfectly with the Matrice 100, Matrice 200 Series (M200, M210, M210 RTK), Matrice 600, and the Inspire 1 drones.

For DJI Zenmuse XT2

Zenmuse XT2 is an upgraded version of XT with an infra-red and visual camera. It can be used along with drones such as Matrice 600 Pro and Matrice 200 Series (M200, M210, M210 RTK).

Application Software
