Three Dimensional Fairway Dynamic Supervisory System Research

The Yangtze River shipping is important strategic significance for our country economic development. The building of the three dimensional fairway dynamic supervisory system is technical support for the Yangtze River shipping development and of great significance to comprehensively upgrade the level of the Yangtze River safety management, to strengthen ship management and to improve the environment of the Yangtze River shipping. But in the present Yangtze River fairway 's supervisory system is mainly two-dimensional graphical display, can not the very good real response scene monitoring environment, demonstrate is quite monotonous, is not very vivid, direct-viewing, brings in the operation easily to the user inconvenient, creates the misoperation.This topic from three dimensional fairway dynamic supervisory system project construction. This system was one synthesized the virtual reality technology, the computer simulation technology, the communication, the networking, and the multimedia technologies and so on many kinds of discipline monitoring domain newest technology, it is successful practice in a monitoring domain. The article have carried on the system analysis and the design to the entire three dimensional fairway dynamic supervisory system, and above the foundations of many technical, three dimensional visualization has realized intuitively, the image three dimensional hypothesized dynamic monitoring scene from the visual, sound effect's aspect parts and so on, and introduced monitoring in the scene, the information inquiry function with emphasis. The user may in roam with the Yangtze River Fairway similar three dimensional monitoring scene, real-time monitors ships, the navigation aid and so on key goal status messages in the Yangtze River fairway, raised the user operation efficiency.This system's research raised the Yangtze River route's intelligent monitoring level, raised the transportation efficiency, simultaneously advanced the Yangtze River digit fairway's construction.
