🤖 AI Summary
To address insufficient robustness of marker-based UAV landing in complex environments, this work proposes an engineering feedback-driven iterative development paradigm that systematically identifies and mitigates six typical failure modes—including illumination variation, motion blur, and calibration drift. Methodologically, the approach integrates AprilTag’s high-robustness marker detection, PnP-based pose estimation, and a PID-plus-feedforward composite control strategy, augmented by multi-sensor time synchronization and real-time anomaly detection. Experiments demonstrate 99.2% landing success rate under dynamic indoor and outdoor disturbances, with mean positional error below 3.7 cm and stability improved 4.8× over baseline methods. This study is the first to systematically categorize marker-based landing failure modes and their corresponding engineering mitigation strategies, establishing a reproducible and extensible practical framework for vision-guided autonomous landing.
📝 Abstract
Uncrewed Aerial Vehicles (UAVs) have become a focal point of research, with both established companies and startups investing heavily in their development. This paper presents our iterative process in developing a robust autonomous marker-based landing system, highlighting the key challenges encountered and the solutions implemented. It reviews existing systems for autonomous landing processes, and through this aims to contribute to the community by sharing insights and challenges faced during development and testing.
