Real-Time Terrain-Following of an Autonomous Quadrotor by Multi-Sensor Fusion and Control
For the application of the autonomous guidance of here a quadrotor from confined undulant ground, terrain-following is the major issue for flying at a low altitude.This study has modified the open-source autopilot based on the integration of a multi-sensor receiver (a Global Navigation Satellite System (GNSS)), a Lidar-lite (a laser-range-finder de
