AI Technical Summary
In complex environments, drones have difficulty accurately identifying the location of mobile platforms. Traditional PID controllers are also unable to adapt to system parameter drift and airflow interference during dynamic landing, leading to landing failure or damage.
The system employs visual QR code recognition combined with IMU's three-axis attitude calculation and adaptive PID controller. It obtains coordinate information by recognizing QR codes through a camera, performs visual-inertial fusion attitude calculation by combining the three-axis attitude angles of the IMU, and uses an adaptive PID controller to dynamically adjust the control gain to ensure that the UAV's attitude is consistent with that of the unmanned vehicle platform.
It enables precise landing of drones in complex environments, improves system stability and landing success rate, ensures the attitude stability and safety of drones under airflow and platform conditions, and achieves safe and smooth landing of drones and mobile platforms.
