摘要: 针对目前三维可视化交互模式难以支持航道船舶信息管理的问题,研究面向航道船舶管理,集三维场景动态实时呈现、场景对象信息管理于一体的三维可视化信息系统。首先,基于已有的静态航道与运动船舶三维场景,构建三维可视化场景;其次,建立描述航道、船舶对象的静态信息库,以及表达船舶运动、水位变化的动态信息库;最后,在三维平台上实现场景对象与其属性信息间的双向查询及数据更新等功能。实例表明,系统能够有效实现航道闸口段管理的可视化与信息化。

Abstract: Abstract: In view of the problem that 3D visualization interaction pattern is difficult to support the channel and ship information management at present, this paper researches a 3D visualization information management system, which combines with the realtime presentation of dynamic 3D scene, the information management of scene object as a whole oriented channel and ship management. Firstly, based on the existing 3D scene which contains static channel and moving ships, 3D visualization scene is constructed. Secondly, this paper establishes a static information database describing waterway and ship objects, and a dynamic database expressing ship's motion and water level's changes. Finally, it also shows us some functions on 3D platform, such as supporting information bidirectional query of scene’s objects and their attributions, data update. Examples show that the constructed system of this paper effectively makes the management of channel gate section with visualization and informazation.

Key words: OSG, 3D dynamic rendering, information management, human-computer interaction
