Research on 3D Simulation Technology Application in Navigation-Aids Management

3D simulation technology can be used to build vivid 3D maritime virtual environment,as well as to simulate navigation-aids and the synthesis visual effect with surrounding maritime environment under complicated maritime conditions,such as daytime,night,bad-visibility and different levels of waves,etc,and to present sceneries and navigation-aids directly,vividly,completely.According to navigation-aids layout scheme and the design of ship tonnage,ship type, sea-route and hydrometeorological information,based on large ship maneuvering simulator,to build a 3D synthesis traffic maritime environment suitable for port actual condition with ship navigation simulation,is useful for evaluating the effect of navigation-aids layout scheme,and verifying the feasibility of the scheme,so as to put forward an optimum scheme.In this paper,the actual application of 3D simulation technology on navigation-aids layout is introduced through analyzing the navigation effect of beacons in Xiamen Port and investigation cases of main sea-route buoy layout.The application of 3D simulation technology provides a vast imagination space for navigation-aids design,construction and management,and gets closer to the developing proposal of IALA's "Navigation-aids 3D Display".
