UAV LiDAR (Light Detection and Ranging) + SLAM (Simultaneous Localization and Mapping) 3D refers to the integration of LiDAR sensors with UAVs to capture three-dimensional data of an area. LiDAR uses laser pulses to measure distances to objects, generating precise 3D point clouds. SLAM technology allows the UAV to navigate and simultaneously map its surroundings in real-time, enabling autonomous flight and accurate 3D mapping even in complex environments.
