摘要增强现实（Augmented Reality，简称 AR），通过计算机产生的感官输入如声音、视频，图形或GPS数据对现实世界物理环境元素进行实时地、直接或间接地增强。增强现实提供了在一般情况下，不同于人类可以感知的信息。借助先进的AR技术（如增加计算机视觉货物体识别），用户可以与周围的现实世界进行交互。

增强现实看起来像一个未来的概念，但在2013年，这将在我们的数字生活中得到实现。2013年必将是“增强现实之年”。64930

本课题主要研究分析了国内外增强现技术的研究现状和发展趋势，重点阐述增强现实技术的理论基础，包括增强现实技术的基本定义和关键技术。增强现实系统的设计和实现主要基于Unity3D开发工具，采用Vuforia SDK搭建了一个实时交互建模平台。通过此交互平台，了解Vuforia软件开发包的体系结构和工作流程，研究学习实现增强现实系统的关键步骤，完成增强现实系统的设计与开发。本课题针对Vuforia SDK的特点，设计了5个简单的增强现实应用。在这些应用中，不仅利用常见的菜单交互方式实现对虚拟模型的控制和渲染，还可以通过场景中特定的标识物与虚拟模型交互，进而控制虚拟模型，充分展现增强现实的魅力。

Title Design and Development of Augmented Reality System Based on Unity3D                                                   

Abstract Augmented reality (AR) is a live, direct or indirect, view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data. It is related to a more general concept called mediated reality, in which a view of reality is modified (possibly even diminished rather than augmented) by a computer. As a result, the technology functions by enhancing one’s current perception of reality. By contrast, virtual reality replaces the real world with a simulated one. With the help of advanced AR technology (e.g. adding computer vision and object recognition) the information about the surrounding real world of the user becomes interactive and digitally manipulable.

Augmented reality may seem like a futuristic concept, but it will be a reality of our digital lives in 2013. 2013 must be the year of augmented reality. 

This topic mainly studies and analyses the research status and development trend of Augmented Reality at home and abroad，focusing on the theoretical basis of augmented reality technology, including basic definitions and key technology of augmented reality technology. Mainly based on the Unity3D development tool, Augmented Reality system builds a real-time interactive modeling platform using Vuforia SDK. With this interactive platform, we understand the architecture and workflow of Vuforia SDK, learn the key step of achieving augmented reality system, and complete the design and development of augmented reality system. Aimming at the feature of Vuforia SDK， the topic designes five simple augmented reality applications. In these applications, we not only use common menu controlling and rendering virtual model, but also interact with the virtual model through specific markers in the scene, and then control the virtual model, fully demonstrate the charm of augmented reality technology.
