摘　　要：针对国内的基于移动增强现实技术的教育产品大多数使用移动增强现实开发包进行二次开发,不具有完全的自主知识产权这个问题,应用具有自主知识产权的识别技术和跟踪注册技术,开发了Android系统下的移动增强现实光学平台。在3D渲染绘制方式上使用专业渲染引擎Unity3D替代底层OpenGL ES代码的编写,解决了Unity3D与移动平台IDE的数据通信、坐标转换、融合显示和系统集成等问题。此方式解决了编写底层OpenGL ES代码进行3D渲染存在的3D绘图程序设计复杂、模型更换困难、交互性差、无法跨平台等问题,且3D渲染帧率可达60帧。该平台应用于移动教育领域,是具有易操作性、趣味性和先进性的实验教学辅助工具,可激发学习兴趣、提高学习效果。Most of the existing education applications based on mobile augmented reality technology were developed by using commercial SDK. To solve this problem,optical experimental platform of mobile augmented reality on Android OS was developed by the authors. Object recognition,object tracking and 3D model rendering functions with independent intellectual property rights were applied in this platform. Specially,professional rendering engine Unity3 D was selected to complete 3D rendering instead of writing underlying OpenGL ES code in this paper. The implementation of data communications,coordinate transformation,fusion display and systems integration between Unity3 D and Android was given in this paper. As a result,the frame rate of 3D rendering is up to 60 frames per second. This optical experimental platform can be used as an auxiliary software of traditional experimental teaching with better user interaction experience. It can encourage learning interest and improve learning efficiency of students.
