Special Issue Information

Dear Colleague,

The Special Issue titled "Inventory Monitoring and Control through High-Level Coordination of Drone Swarms" aims to explore advanced methodologies and technologies for leveraging drone swarms in process control and automation. This issue focuses on innovative solutions for inventory monitoring in warehouses, both indoors and in open environments, using synchronized drone operations. It emphasizes the integration of advanced predictive control algorithms to optimize swarm behavior, enabling precise path planning and efficient task allocation. Key topics include environmental mapping using camera and LIDAR systems, real-time anomaly detection, and adaptive scheduling of time-sensitive aerial surveys for monitoring dynamic changes, such as environmental shifts or stock fluctuations. Additionally, this issue invites contributions on cooperative localization strategies for enhanced positional accuracy, energy-efficient mission planning for extended operation, and secure communication protocols for real-time data exchange among drones. Further, studies on swarm resilience, self-healing capabilities, and the integration of AI-driven decision-making processes to improve coordination and adaptability are highly encouraged. The issue aims to provide a comprehensive overview of the state of the art in drone swarm applications, offering solutions for industries ranging from logistics and agriculture to environmental monitoring and disaster management.

A single drone collects data, but a fleet builds a complete picture, and this is the primary objective of this study. To address this goal, a swarm-based drone system has been designed in which multiple drones follow one another to collect data from diverse perspectives. Such a strategy demonstrates strong potential for use in critical fields such as search and rescue operations. This study introduces the first unified framework that integrates autonomous formation control, real-time object detection, and multi-source data fusion within a single operational UAV-swarm system. A high-fidelity simulation environment was built using Unreal Engine with the AirSim plugin, featuring a lightweight QR code tracking algorithm for inter-drone coordination. The drones were employed to detect vehicles from various angles in real time. Two types of experiments were conducted: the first used a pretrained YOLO model, and the second used a custom-trained YOLOv8-nano model, which outperformed the baseline by achieving an average detection confidence of 90%. Finally, the results from multiple drones were fused using various techniques including temporal, probabilistic, and geometric fusion methods to produce more reliable and robust detection results.

Air-to-ground visual target persistent tracking technology for swarm drones, as a crucial interdisciplinary research area integrating computer vision, autonomous systems, and swarm collaboration, has gained increasing prominence in anti-terrorism operations, disaster relief, and other emergency response applications. While recent advancements have predominantly concentrated on improving long-term visual tracking through image algorithmic optimizations, insufficient exploration has been conducted on developing system-level persistent tracking architectures, leading to a high target loss rate and limited tracking endurance in complex scenarios. This paper designs an asynchronous multi-task parallel architecture for drone-based long-term tracking in air-to-ground scenarios, and improves the persistent tracking capability from three levels. At the image algorithm level, a long-term tracking system is constructed by integrating existing object detection YOLOv10, multi-object tracking DeepSort, and single-object tracking ECO algorithms. By leveraging their complementary strengths, the system enhances the performance of the detection and multi-object tracking while mitigating model drift in single-object tracking. At the drone system level, ground target absolute localization and geolocation-based drone spiral tracking strategies are conducted to improve target reacquisition rates after tracking loss. At the swarm collaboration level, an autonomous task allocation algorithm and relay tracking handover protocol are proposed, further enhancing the long-term tracking capability of swarm drones while boosting their autonomy. Finally, a practical swarm drone system for persistent air-to-ground visual tracking is developed and validated through extensive flight experiments under diverse scenarios. Results demonstrate the feasibility and robustness of the proposed persistent tracking framework and its adaptability to wild real-world applications. Full article
