Autonomous drones utilize several technologies for navigation, including GPS, lidar, and computer vision. GPS provides location data, allowing drones to determine their position on a map. Lidar uses laser scanning to create detailed 3D representations of the environment, enabling obstacle detection and route planning. Computer vision employs cameras and machine learning techniques to help drones interpret their surroundings, recognize objects, and navigate dynamically. Together, these technologies facilitate precision flying and enhance operational safety in various applications, from delivery to surveillance.
