The researchers unveiled a holographic drone control system. It is more efficient than the first-person video and requires less data.
Scientists from the Hong Kong University of Science and Technology have presented a new interface for controlling drones. It uses holographic augmented reality hardware to create 3D terrain maps in real-time. Focusing on them, drones can only indicate the target to which they need to fly. They will do the rest themselves.
The holographic interface works with Microsoft HoloLens headset. It generates augmented reality content in the form of a map that can be viewed from any angle. The system also conveys a sense of the height and depth to which the drone is oriented. HoloLens then sends commands to the drone, identifying its next target on a holographic map. The autonomous drone flies to the location, updating the 3D map as it travels.
The University of Hong Kong team needs to finalize the control system for the unmanned aerial vehicle. Initially, drone data was transmitted using Wi-Fi within the test space, and cellular communications transmitted information with delays. The researchers also noted that so far, the management model “works in a very limited space.” In one of the cases, the drone late loaded the altitude data and crashed.
However, scientists are confident that 3D map data will be more effective navigators than first-person video. In addition, during long flights, the devices will need six times less data, while their quality will not change. In the future, the team wants to combine both streams to reduce traffic even more.
