Abstract�� The important research field of virtual reality (VR)is how to construct image-b ased virtual space by image-based rendering techniques. How to enlarge the extent of freedom is the key issue. Free image-based virtual space (FIBVS) is a kind of this virtual space where users can manipulate freely. A method called conspherical mosaics to construct FIBVS was presented, and user s could look down and look up freely when they walk in it. The idea of hyperlink was used to organize those virtual objects so that users could manipulate these objects in FIBVS. The experimental results show that users can manipulate space freely in FIBVS.
Keywords�� computer graphics   computer vision   image processing   virtual reality   image -based rendering
