Abstract

A single unmanned surface vehicle (USV) designed for marine missions suffers from limited payload, low efficiency and weak intelligence, while a swarm of USVs shows significant advantages in mission flexibility, diverse payload and task efficiency. One of the key issues for an USV swarm is how to achieve highly efficient collaborative perception. To address this issue, a method framework of collaborative surface target detection and localization based on multiple sensors for a swarm including 4 USVs is designed. First, perception systems are constructed, a joint calibration method for different sensors is proposed, and a lightweight target detection method improved with attention mechanism and lightweight adaptive spatial feature fusion is designed. Second, a specialized fusion method using sensor principles based on an extended Kalman filter (EKF) is proposed for a single USV to obtain a target state model. Third, the obtained target models from different USVs are registered with fuzzy matching and integrated into the complete model in a geographic coordinate system. The proposed method is applied to the collaborative perception system on our developed 4 USV swarm and verified in real marine environment and simulation. Experimental results show that our proposed method framework significantly improves the accuracy, efficiency, and reliability of the target detection and localization. The proposed LAF-YOLOv8-s reduces the model size by 5.1M, while the mean average precision (mAP) reaches 68.7%, which is significantly superior to other methods. The average collaborative localization error is reduced by 2.9m. The dataset is available at https://github.com/maochenyu1/WSLight.
无人水面飞行器群的水面目标协同探测和定位方法
为执行海洋任务而设计的单个无人水面飞行器(USV)存在有效载荷有限、效率低和智能弱等问题,而无人水面飞行器群则在任务灵活性、有效载荷多样性和任务效率方面具有显著优势。USV 星群的关键问题之一是如何实现高效的协同感知。为解决这一问题,本文设计了一种基于多传感器的水面目标协同探测和定位方法框架,适用于包括 4 艘 USV 的星群。首先,构建了感知系统,提出了不同传感器的联合校准方法,并设计了一种利用注意力机制和轻量级自适应空间特征融合改进的轻量级目标检测方法。其次,针对单个 USV,提出了一种基于扩展卡尔曼滤波器(EKF)、利用传感器原理的专门融合方法,以获得目标状态模型。第三,将不同 USV 获得的目标模型进行模糊匹配注册,并在地理坐标系中整合成完整的模型。我们将提出的方法应用于我们开发的 4 USV 蜂群协同感知系统,并在真实海洋环境和模拟环境中进行了验证。实验结果表明,我们提出的方法框架显著提高了目标探测和定位的准确性、效率和可靠性。提出的 LAF-YOLOv8-s 减少了 5.1M 的模型大小,平均精度(mAP)达到 68.7%,明显优于其他方法。平均协作定位误差减少了 2.9 米。数据集可在 https://github.com/maochenyu1/WSLight 上获取。
