基于移动终端的增强现实是当前移动应用和人机交互领域备受关注的热点之一，现有的增强现实开发技术多采用简单的模板匹配方式进行标识物的识别，准确率较低，受光照和遮挡的影响较大，常导致跟踪失败。该文提出了一种基于 Unity3D 的移动增强现实自动导览方法，利用 Unity3D 对场景进行三维建模，由 Vuforia 引擎检测和跟踪标识物特征点，根据不同标识物的相对位置和姿态在视平面上绘制对应的3D 模型、设置动画、播放视频，采用虚拟按钮方式进行虚实交互。实验结果表明，该方法能够在终端连续移动过程中无缝切换虚实叠加的效果，对光照变化和遮挡处理的鲁棒性较好，可用于校园、展会、旅游景点等室内外环境的自动导览。

Augmented reality(AR) based on mobile terminal is one of the current hot fields in mobile applications and human-computer interaction .The common AR techniques mostly adopt simple template matching methods to identify mark-ers which are inaccurate and easily influenced by the change of light or occlusion ,and often lead to tracking failure .An auto-matic navigation method of mobile AR is proposed based on Unity3D in this paper .Firstly ,3D models of the scene are con-structed using Unity3D and features points of the markers are detected and tracked by Vuforia engine .Then ,according to the relative positions and angles of different markers ,the 3D models can be rendered and animations or videos are played on the visual screen .Virtual buttons are used for virtual-reality interaction .Experimental results show that this method can switch seamlessly augmented reality effects during the terminal moving process and have good robustness to illumination change and occlusion .It can be applied for automatic navigation of indoor and outdoor environments including schools ,exhi-bitions ,tourist spots ,etc .
