增强现实可实现真实场景与计算机虚拟信息的融合．研究了基于标志的增强现实技术，采用齐次变换实现基于标志的增强现实三维注册关键技术，改进了坐标齐次变换支持多标志识别，可同时对多个三维虚拟模型进行平移、旋转、缩放的刚体变换，实现虚拟物体的全方位操作．以古生物魔法书作为实例，展现了增强现实技术在教学中的应用优势，探讨了其在教育中的应用方式、条件需求和关键技术，实例结果显示增强现实进入教学领域可行性．

英文摘要：

Augmented reality can combine virtual information with real situation. This paper focused on marker based augmented reality. We presented a homogeneous transformation method to realize key technology of 3D registration. An improved homogeneous transformation method could support multi-marker identification. 3D virtual modal could be transformed, rotated and scaled. A paleontological magic book for instance was developed which showed superiority of augmented reality technology applied in education. By the magic book in this paper, we discussed how to use augmented reality for education, what the most important requirement was and related key technology. Data showed feasibility of augmented reality applied in education.
