Unmanned aerial vehicle (UAV), military aircraft that is guided autonomously, by remote control, or both and that carries sensors, target designators, offensive devices or electronic transmitters designed to interfere or destroy enemy objectives. For LIDAR and photogrammetric mapping, the UAV is programmed to fly over an area in an autonomous way, by navigating through reference points. The drone's camera will take pictures at intervals of 0.5 or 1 second. These photos are then joined together using specialized photogrammetry software to create the 3D images.
In the case of drones that lack automation, control always lies with the pilot or operator. In low-cost drones, the pilot uses visual tracking to determine position and orientation. In some cases, this is done from the ground, depending on the relative position of the pilot. In the case of drones equipped with integrated cameras, visual data is transmitted to the pilot's screen.
The most important parts of a drone are the operating system and the flight controller. The batteries power the rotors, which causes them to rotate the propellers and generate lift. The flight controller uses the data collected by accelerometers, barometers, magnetometers, gyroscopes and the controller to stay in the air. An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board.
An unmanned aerial vehicle (UAV) is defined as a motorized aerial vehicle that does not carry a human operator, uses aerodynamic forces to lift the vehicle, can fly autonomously or be piloted remotely, can be disposable or retrievable, and can carry a lethal or non-lethal payload. Classification of UAVs by the army's unmanned aerial systems (UAS) according to the weight, maximum altitude, and speed of the UAV component. Unmanned aerial vehicle technology ranges from the aerodynamics of the drone and the materials used in the manufacture of the physical UAV to the circuit boards, the chipset and the software, which are the brain of the drone. A similar term is an unmanned aerial vehicle (UAVS) system, a remotely piloted aerial vehicle (RPAV) and a remotely piloted aircraft system (RPAS).
Unmanned aerial vehicles are a component of an unmanned aircraft system (UAS), which includes the addition of a ground controller and a communications system with the UAV. The malicious use of unmanned aerial vehicles has led to the development of technologies against unmanned aerial systems (C-UAS).
