摘　　要：在增强现实系统中,真实物体和虚拟物体除了要实现视觉上的融合之外,还要能够实现视觉交互和物理交互。仿真系统采用了基于单目视觉的ARToolKit增强现实开发平台,首先对CMOS摄像头采集的图像进行处理,利用模式识别的方法对标识物进行图像匹配,然后对从标识物坐标系到摄像机坐标系的变换矩阵进行计算,实现虚实注册,最后通过对标识物空间位置的改变实现了虚实物体间的单向物理交互。实验结果表明,该系统操作简单直观,具有良好的实时性,交互性及可扩展性。In the Augmented Reality （AR） system, virtual objects and real objects of the AR system should realize not only the fusion of vision but also the interaction of vision and physics. This simulation system adopts ARToolKit, a kind of developing platform of AR based on monocular vision. It firstly processes image collected by CMOS camera, and matches images of the markers by using pattern recognition, then calculates transformation matrix from coordinate system of the markers to that of the camera in order to realize registration, and finally realizes the one -way physical interaction through the change of the markers＇ position. The results show that this system is easy to ooerate, and is of preferable feature of real -time. interaction and expansion.
