摘　　要：阐述增强现实技术,将预设的教学内容叠加在实物缩比模型上,可进行静动态展示,支持实时交互。通过对实物模型进行识别及定位,建立虚拟场景坐标系与实物坐标系的映射关系,完成虚拟场景的三维注册,实现基于混合现实的可实时交互式教学过程。探讨使用Unity 3D和EasyAR等工具开发,实验证明该系统对场景有较高的识别率,能够在移动平台上实现实时的识别、渲染与交互。This paper describes the augmented reality technology.The preset teaching content is superimposed on the physical scale model,which can perform static and dynamic display and support real-time interaction.Through the identification and positioning of the physical model,the mapping relationship between the virtual scene coordinate system and the physical coordinate system is established to complete the 3D registration of the virtual scene and realize the real-time interactive teaching process based on mixed reality.It discusses the use of Unity 3D and EasyAR and other tools for development.Experiments show that the system has a high recognition rate for scenes,and can realize real-time recognition,rendering and interaction on mobile platforms.
