It is the most commonly used machine for inspecting bridge structures. We have the possibility to mount the camera on the top of the UAV and thanks to that we can see perpendicularly under the bridge. With the DJI Z30 camera, we can then simply zoom in on the point of interest from a long distance, so we don’t have to fly all the way to the point of interest. With these capabilities and equipment, we then have GPS photos at all times. In most cases we cannot find GPS satellites under the bridge because of the steel and concrete structures. Using the Inspector app, we can then see the photos taken directly on the 3D model of the bridge, which is also determined by GPS coordinates.

The most common task for the DJI Matrice 210 V2 is monitoring cultural events and other activities where constant aerial surveillance is required. The Elistair Light-T V4 allows us to do just that. More details about this device can be found directly in the kit.

The most important difference is the image transmission technology. In version 1, data is transmitted using Lightbridge 2.0, which has a range of up to 3.5 km in line-of-sight between the pilot and the UAV. For the more modern version 2, DJI has come up with a new technology called OcuSync 2.0, which has a range of up to 5 km in line-of-sight. Not only is the range increased with this innovation, but the data transmission power itself is stronger. As a result, image dropouts in trouble spots are much less frequent.

Another difference is the addition of LED lights on the top and bottom of the UAV, right next to the impact sensors. Last but not least is the stereoscopic light for easier orientation in flight traffic for surrounding pilots.
