| 摘 要： | 最近几年基于图像的虚拟现实技术渐渐引起人们的兴趣。它是一种通过实景拍摄获取图像来表示虚拟场景的技术。提出了一种基于图像的三维空间漫游方法 ,它是基于视图变形技术的原理 ,在三维空间中选定三幅视图构成一组图像基 ,再由这组基插值中间任何姿态视图 ,最后这些视图以视频方式显示出来。它避免了 3D重建问题 ,人们可以从任何视点或视向来观赏对象。

| Abstract: | Techniques of image based virtual reality have increasingly interested people in recent years. They are representing virtual environment techniques with images which are acquired through photographing. The paper puts forward an approach of image based three dimensions space navigation. In 3 dimensions space, three views are selected to form a view base which are used to interpolate in between any pose views based view morphing technique. Finally, these views are showed by means of video. It avoids a problem of 3D reconstruction. People can obverse an object from arbitrary viewpoints or view directions. |
