Evaluation of bathymetry and resistance to water flow in inland river for intelligent connection unmanned vessel
Unmanned vessel non-tide depth measurement and network RTK technology were used to conduct water depth measurement experiments in inland rivers,based on which the performance of the independently developed unmanned vessel was evaluated from three aspects of depth measurement accuracy,path tracking and the maximum resistance to water flow.The results show that the unmanned vessel has high accuracy in water depth measurement,meets the requirements of relevant specifications,and has strong resistance to water flow and good path tracking ac-curacy under the condition of water flow velocity less than 2.0 m/s.The maximum safety threshold of water flow ve-locity for field operations is 5.0 m/s.
