The technologies underpinning autonomous drones include artificial intelligence (AI), machine learning, and computer vision. AI enables drones to make real-time decisions based on data gathered from their environment, while machine learning allows them to improve their performance over time through experience. Computer vision equips drones with the capability to interpret visual information, essential for navigating, avoiding obstacles, and recognizing objects. Furthermore, advanced sensors like GPS and LiDAR enhance accuracy in mapping and tracking, contributing to the reliability and effectiveness of autonomous drone operations.
