Research On Image-Based Rendering Panorama Space Based On Virtual Reality

In this thesis, the first, we compare image-based rendering with geometry modeling based rendering and analyze the advantages of image- based rendering in the field scene generation are described. The second ,we put forward a kind of theory and some techniques for virtual space to walkthrough .We study the characteristics, type, components, space organization and manipulation. By extending the model hypermedia, we get the space information organization model of virtual space, which makes the panorama organization getting special characteristic. Further more, we modify and implement the algorithm of producing 360-degree cylindrical panorama. The algorithm includes cylindrical projection algorithm, image matching algorithm, seamless linking algorithm and cylindrical to planar projection algorithm. The last, we study virtual scene navigating system model, based on time and space of manipulation, utilize Java Applet technique to realize the panorama-browser with button controlling.
