摘　　要：增强现实技术可以把计算机产生的虚拟物体或其它信息合成到用户看到的真实场景中。将增强现实技术与基于图像的绘制技术有机的结合起来,介绍了虚拟实景空间的构造,探讨了虚拟物体与实景空间的合成方法,给出了一种在虚拟实景空间中漫游的机制及其实现方法,综合考虑了机制的复杂度和漫游的自由度,在两者之间取得了平衡,该方法具有较好的实用性。Augmented reality can merge computer-generated virtual objects or other additional information into tbe user＇s view of the real world. AR technique and IBR technique is used to construct an image-based virtual space system, which can add computer-generated virtual objects into the real image space. The process of building the image-based virtual space is introduced and the combination of virtual objects and the real image space is discussed at first, and then a wandering schema and its implementation in virtual imaging space is proposed. This proposal comes into balance between complexity and walking freely and has excellent practicability.
