Virtual test scenarios occupy an important position in the evaluation of smart ships.Digital twin technology can describe and predict the real environment and realize the interactive mapping of smart real environment and virtual scenarios.This paper explores how to apply digital twin to smart ship virtual test,constructs ship and environment digital twin to realize how and where the ship acquires data in real environment,what kind of data is acquired and mapped to virtual test scenes,and seeks more accurate parameters.Initially,a ship virtual test scenario architecture based on digital twin is constructed,based on which the application of virtual test before and after and ship remote operation delay optimization is carried out,and the architecture has certain validity and reliability.The digital twin-based technology can improve the efficiency and operation accuracy of the intelligent ship virtual test system and enhance the reliability of the experimental results.
