DJI Zenmuse H20T
The most commonly used for the need of the IZS (Integrated Rescue System). Combination of a total of 4 different sensors. But there are also plans to integrate it into our inspection system. It has an optical ZOOM camera for detailed monitoring, a thermal camera for finding fire hotspots or searching for people, a laser rangefinder for GPS targeting of important points and counting their distance from the UAV, and a wide-angle camera for a general overview.
Specification
Object tracking
The undeniable advantage of this sensor is its AI. Thanks to this feature and by combining all the sensors on the paylod, the H20T can track an object almost perfectly. Tracking is done by the ZOOM camera, which scans the object being tracked, and if the object is lost, the camera continues to predict its movement until it finds it again. If after some time it does not see the object again, it starts slowly zooming out until it finds the object again or is at its zoom limit.
Regular inspection
Another feature is periodic scanning used mainly for inspections. Once the object is photographed, the UAV stores the necessary data, i.e., the camera zoom, camera tilt, and GPS position of the UAV. The next time the UAV inspects the same object, it flies to the original position, rotates the camera itself, and produces an image that is exactly the same as the original one. Thanks to this feature, we are then able to observe changes on the object over time.
