摘要

本研究为自主潜水器(AUV)开发了基于视觉的对接系统(VDS),通过集成智能物体识别和深度强化学习(DRL),显著提高了对接性能。该系统利用可变信息停靠点(VID)对自动潜航器进行精确的多传感器停靠识别,从而克服了复杂和不可预测环境中的传统导航限制。VDS 采用基于图像的视觉伺服(IBVS)技术,可有效地将二维视觉数据转换为精确的三维运动控制指令。它集成了用于物体识别的 YOLO(You Only Look Once 的缩写)算法和深度确定性策略梯度(DDPG)算法,提高了连续运动控制、对接精度和适应性。在成功大学拖曳坦克上进行的实验验证表明,VDS 增强了控制稳定性和运行可靠性,与以前的方法相比,深度控制的平均绝对误差(MAE)减少了 42.03%,俯仰控制减少了 98.02%。这些结果证实了 VDS 的可靠性及其改变 AUV 停靠的潜力。

The docking control system of an autonomous underwater vehicle combining intelligent object recognition and deep reinforcement learning

The docking control system of an autonomous underwater vehicle combining intelligent object recognition and deep reinforcement learning
This study develops a visual-based docking system (VDS) for an autonomous underwater vehicle (AUV), significantly enhancing docking performance by integrating intelligent object recognition and deep reinforcement learning (DRL). The system overcomes traditional navigation limitations in complex and unpredictable environments by using a variable information dock (VID) for precise multi-sensor docking recognition in the AUV. Employing image-based visual servoing (IBVS) technology, the VDS efficiently converts 2D visual data into accurate 3D motion control commands. It integrates the YOLO (short for You Only Look Once) algorithm for object recognition and the deep deterministic policy gradient (DDPG) algorithm, improving continuous motion control, docking accuracy, and adaptability. Experimental validation at the National Cheng Kung University towing tank demonstrates that the VDS enhances control stability and operational reliability, reducing the mean absolute error (MAE) in depth control by 42.03% and pitch control by 98.02% compared to the previous method. These results confirm the VDS's reliability and its potential for transforming AUV docking.
