论文摘要
本文报告了对使用一辆或多个无人体表面车辆（USV）快速识别通道快速识别的通道问题进行的调查。一种称为基于建议的自适应通道搜索（PBAC）的新算法作为一种潜在的解决方案，可改善当前方法。将PBAC的经验表现与割草机测量和马尔可夫决策过程（MDP）计划进行了比较，该计划具有两个最先进的奖励功能：上限置信度（UCB）和最大价值信息（MVI）。通过比较使用一个，两个，三个或四个USV来识别连续通道所需的时间来评估每种方法的性能。在十个模拟的测深场景和一个野外区域中比较每种方法的性能，每种方法都有不同的通道布局。模拟和现场试验的结果表明，平均多车辆PBAC优于基于割草机，UCB和基于MVI的方法，尤其是在使用至少三辆车时。
This paper reports an investigation into the problem of rapid identification of a channel that crosses a body of water using one or more Unmanned Surface Vehicles (USV). A new algorithm called Proposal Based Adaptive Channel Search (PBACS) is presented as a potential solution that improves upon current methods. The empirical performance of PBACS is compared to lawnmower surveying and to Markov decision process (MDP) planning with two state-of-the-art reward functions: Upper Confidence Bound (UCB) and Maximum Value Information (MVI). The performance of each method is evaluated through comparison of the time it takes to identify a continuous channel through an area, using one, two, three, or four USVs. The performance of each method is compared across ten simulated bathymetry scenarios and one field area, each with different channel layouts. The results from simulations and field trials indicate that on average multi-vehicle PBACS outperforms lawnmower, UCB, and MVI based methods, especially when at least three vehicles are used.
