【摘要】 虚拟现实技术是计算机技术、计算机图形学、传感技术、人体工程学、多媒体技术等一系列高新技术的汇集。这是一种人机交互的新的手段来解决现实世界中问题的新方法。目前,其应用前景和科学价值已经引起了广泛关注,在各个领域起着重要的作用,如航空航天、机械设计、信息管理、军事训练、医学治疗、教育教学和影视娱乐等。本文针对当前国内外坦克训练模拟器开发和使用的具体情况,提出了坦克虚拟现实驾驶模拟平台的设计思想。研究中建立了坦克动力学模型,重点分析了坦克直线行驶和转向行驶的受力情况及其动力学模型。针对仿真系统对三维场景和坦克模型高逼真度的要求,采用三维建模软件MultiGen-Creator,及结合实际坦克的具体参数,建立了坦克的三维模型及三维场景模型。并利用实时仿真软件Vega,建立了符合本系统要求的仿真控制程序。为增加用户的沉浸感,使环境更加逼真,并对雨雪雾等的自然景观特效进行仿真。通过测验验证,较好的实现了仿真效果,基本上满足了视景仿真系统所要求的实时交互性和真实的沉浸感。最后对本文的研究工作进行了总结,和本文存在的不足以后的工作做出了展望。更多还原

【Abstract】 Virtual reality is computer technology, computer graphics, sensor technology, human engineering, multimedia technology and a series of high-tech pool. This is a new means of human-computer interaction to solve real world problems the new method. At present, its prospects and scientific value have attracted wide attention in various fields play an important role, such as aerospace, mechanical design, information management, military training, medical treatment, education and teaching and video entertainment.In this paper, the training simulator for the current domestic and international tank development and use of the specific circumstances raised tank virtual reality driving simulation platform design. Study established the tank kinetic model, analyzed the tank straight driving and steering a moving force and its dynamic model. According to the simulation system model of three-dimensional scene and the tank requirements of high fidelity, three-dimensional modeling software MultiGen-Creator, and combined with the specific parameters of the actual tanks, tank set up three-dimensional model and three-dimensional scene model. And application of Vega, built according to the requirements of the system simulation control program. And to further increase user immersion and to be more realistic the environment, simulation of the special weather snow and fog. Through testing to achieve a better simulation results, to meet the visual simulation system requires real-time interactivity and real immersion. The last major work is summarized and the shortcomings in the work of the future prospects made.更多还原
