摘要:

目前,对河流的环境监测和调查工作主要是用人工操作的船只进行的。在该领域中,区域的自主覆盖对于提高覆盖的质量和效率都是至关重要的。本文利用人类在河流勘探和数据汇集策略方面的专业知识,使用自主水面车辆(ASV)自动化和优化这些过程。特别是,提出了三个确定性算法的部分和完整的覆盖范围内的河流段,提供不同的路径长度,覆盖密度,和转向模式。这些策略提高了准确性和效率相比,人类performance.The提出的方法进行了广泛的测试,在模拟使用不同形状和大小的真实河流的地图。此外,为了验证它们在现实世界中的性能,这些算法成功地部署在美国南卡罗来纳州康加里河的几个部分,在该领域产生了超过35公里的覆盖轨迹。

英文摘要:

Environmental monitoring and surveying operations on rivers currently are performed primarily with manually-operated boats. In this domain, autonomous coverage of areas is of vital importance, for improving both the quality and the efficiency of coverage. This paper leverages human expertise in river exploration and data collection strategies to automate and optimize these processes using autonomous surface vehicles(ASVs). In particular, three deterministic algorithms for both partial and complete coverage of a river segment are proposed,providing varying path length, coverage density, and turning patterns. These strategies resulted in increases in accuracy and efficiency compared to human performance.The proposed methods were extensively tested in simulation using maps of real rivers of different shapes and sizes. In addition, to verify their performance in real world operations, the algorithms were deployed successfully on several parts of the Congaree River in South Carolina, USA, resulting in total of more than 35km of coverage trajectories in the field.
