| 摘 要： | 多年来,造型技术模拟自然界物体形状生成的图像都显得过于规则化和“人工化”。有鉴于此,提出了基于图像的虚拟现实。而完善的虚拟现实系统应该支持多自由度的观察,如视点的移动。视点变换就是求视点移动后原始图像变换生成的新视图。以前给出的变换公式都是在同一坐标系下视点移动后生成的视图。此文给出了在任意坐标系下视点移动后生成新视图的公式,以及具体推导过程。

| Abstract: | For many years,simulating the shape of object in natural,model technique is used to synthesize images which are too regular and artificial.So,image-based virtual reality is referred.But perfect virtual reality system should support the observation from max -angle,eg.a motion of viewpoint.There -dimensional warping equation which can be used to synthesize views after changing the viewpoint.Previously,all these views are calculated by there-dimensional warping equation which are in the same coordinate system.In this thesis,the authors have given the process that the view is synthesized after the motion of viewpoint in the arbitrary coordinate system and the process of specific specula-tion. |
