中文摘要	虚实融合也叫增强现实（Augment Reality，简称AR），混合现实（Mixed Reality,简称MR）。它是随着虚拟现实技术在各行各业的广泛应用而发展起来的一项新技术，运用计算机视觉，计算机图形学等技术将用户感知的真实世界和计算机生成的图形图像以及声音等信息互相“叠加”，使真实世界与虚拟世界的信息无缝融合，相互补充和增强。用户沉浸其中，如身临其境，既能处理虚拟的世界，同时又能处理真实的物理世界，真假难辨，毫无区别。随着行业应用的广泛深入和各种电子设备如笔记本，iPad，智能手机设备的普及呈现新的应用趋势，人们越来越追求系统的便携性，个性化，时尚化，智能化，交互性，对这些各色硬件设备及多样软件应用的集成日趋迫切。 尽管目前虚实融合系统的研究已经取得了一定的进展，但比较成熟的商用虚实融合系统均是基于独立工作平台的，价格昂贵，设备间耦合紧密，难以应对各种新型应用。因此，开发一种成本低，通用性实用性强，易于扩展以应对未来复杂需求的虚实融合系统开发集成平台具有广阔的应用前景和现实意义。基于上述背景，针对虚实融合系统应用问题，本文提出了以Delta3D开源游戏引擎作为开放式通用虚实融合系统开发集成平台的思想。 本文的主要研究目标是从开放性，通用性，扩展性等方面分析研究Delta3D开源游戏引擎作为通用虚实融合系统开发集成平台的可行性，并以集成高精头部定位系统作为实例，实现虚实融合系统软硬件的无缝接入，并开发一个应用场景实例直观演示定位结果。高精头部定位系统实现真实三维空间的实时高精定位和姿态感知。应用实例使用Delta3D编辑工具构建虚拟场景，使用传感器等硬件设备实时地与真实世界交互获取物理数据，数据经过集成到系统的高精定位系统及应用程序的处理后，通过骨骼动画技术直观地演示数据的变化，最后将虚实融合的场景实时绘制出来。 本文首先概述了虚实融合的概念，对国内外的研究应用现状及取得的成果进行了细致地研究分析。接着，详细论述了虚实融合系统包括的建模技术，三维渲染技术，交互技术，角色动画技术，四元数等关键技术。然后是基于Delta3D的虚实融合系统的分析设计与实例的实现，取得了预期的实验结果，成功演示了高精头部定位系统，集成了虚实融合系统所需的软硬件，充分验证了Delta3D作为虚实融合系统开发集成平台的通用性和扩展性。最后是本文的总结及对未来虚实融合技术的展望。
英文摘要	Virtual-Real fusion is also called augment reality (AR for short), mixed reality (MR for short).It's a new technology along with the application of virtual reality technology. It applies computer vision, computer graphics and other technology to make the real world and the graphs, images and voices produced by the computer overlapped, make them converge seamlessly and complement or enhance each other. Users immerged in it like being there, they can handle the virtual world and the real world at the same time telling no difference .Following application goes in depth and width, as well as notepads, iPads, intelligent mobile phones and other electronic equipments are more popular, people are tend to the portable, personalized, fashionable, intelligent, interactive systems. So the integration of different hardware and various software applications is especially emergent. Although some progress have been made in this field, the mature systems depend on their unique platforms and always expensive. While the physical equipments are also tight coupling, which is very difficult to fit the new application. Thus, developing a low cost, general, more applicable and more extensible application platform is magnificent to the complicated requirements in the future. Based on these, this paper goes in for taking Delta3D an open source game engine as an open general virtual-real fusion system developing and integating platform to meet these requirements. The goal of this paper is to analyze the feasibility of taking Delta3D as a general virtual-real fusion system developing platform from aspects of open, general and extensibility. As an example, we integrate the high accurate head positioning system into Delta3D. It implements the virtual-real system interactive equipments and software seamless integration and intuitively demonstrates the data variation by the application case. High accurate head positioning system traces the positon and pose in the real world. Application combines of the virtual scenes made by STAGE, integration of high accurate head positioning system, interaction with the real world, data processing, displaying data variation intuitively by skinned mesh animation technology and drawing the virtual-real fusion scenes in real time. Firstly, the paper describes the definition of virtual-real fusion, delicately analyze the research and application situation and achievements both at home and abroad. And then discuss the key technology about virtual-real ...
