【摘要】 随着计算机技术、通信技术及其它相关技术的飞速发展,信息的可视化成为新的应用发展方向,基于分布交互技术的模拟训练研究日益成为当前研究的热点。本文以分布交互式技术的发展状况分析和已开发的二维潜艇模拟器的研究为基础,结合人机交互技术,建立了三维立体分布交互式潜艇航行训练仿真系统,包括虚拟仪表、虚拟舱室等三维实体建模和运动建模。开发了具有虚拟现实特点的视景仿真系统,并实现了实时仿真及交互控制的功能。具体工作包括以下几个部分: 首先,本文通过对分布交互技术及对潜艇模拟器应用情况的分析,阐述了本课题的必要性和现实意义,并提出分布式系统的实现方法和通讯协议,具体设计了基于WinSock的相应的TCP/IP实现。 其次,选用建模软件MultiGen对潜艇舱室和虚拟设备进行建模。建模过程中主要采取基于图形的建模方法,其中包括场景视/音体建模、运动建模以及背景模型的构建。结合虚拟舱室的建模特点,对软件关键技术进行了研究。在建立场景数据库后,对模型进行优化。 然后,采用空间球、数据手套等人机交互设备建立了实时的人机交互系统,并详细阐述了实现原理和方法。另外,基于双目视差原理,我们采用立体成像驱动器,立体眼镜等设备,实现了视景的立体显示。 最后,选用虚拟现实开发软件Vega实现实时漫游,提供了场景漫游的设计过程,并对碰撞检测、交互控制等关键技术进行了详细研究。 目前仿真系统的视景部分、通讯部分、人机交互部分均已完成了实际的研制工作,并取得了良好的实验效果,即将投入海军的使用。更多还原

【Abstract】 With the rapid speed development of computer science, communication technology and other technologies, the visibility of information becomes the new field of application development and the simulation training technology based on DIS (Distributed Interactive Simulation) is being increasingly the focus of currently research. This paper analyze the status of the development of DIS technology and the application of developed two-dimensions simulator, base on these, and combine the technology of man-machine interactive, establish simulating system of three-dimensions, stereo, Distributed and interactive for Submarine navigated training. Including the 3Ds static model and active model setting up of the visual instrument and visual cabin and so on, and develops the scene simulation system, which has the VR characteristic. The research work includes several parts as fellow:First, the significance and importance of this task is presented by carefully analyzing the status of the DIS technology and application of submarine simulator in this paper. The method of how to realize the distributed system and agreement of communication is also presented. The TCP/IP realization base on WinSock is also designed in this paper.Second, a software named MultiGen is used to model the visual instrument and visual submarine cabin. In the process of modeling, the method is mostly based on graphics, which includes the solid models, sound models, active models and background models. The key technology of the software relating to the characteristic of modeling visual cabin is researched. After set up the scene database, the models are well optimized.Third, Real-time man-machine interactive system based on space ball, data glove and so on is established. The paper presents the theory and methods of the system. Based on two eyes parallax, we decide to use stereoscopic glasses and 3D imaging driver realized the stereo scene display.Finally, Real-time roaming is fulfilled by using a VR development software named Vega and the design process of scene roaming is offered. The keytechnology of collision check-up and interactive control are also finely researched in this paper.The project of simulator with visual system, communicating system, Man-machine interactive system has been accomplished and the experiment also has well been done. Recently, the visual system and related devices will consign to navy.更多还原
