摘要
视点变换就是在虚拟现实技术中求视点移动后原始图像变换生成的新视图。以前给出的用于全景图像的变换公式都是基于平面或柱面全景图像。论文给出了球体针孔摄像机模型在warping方程中生成新视图的公式,以及具体推导过程。
Three-dimension warping equation which can be used to synthesize views after changing the viewpoint in virtual reality system,Previously,all these views are calculated by the three-dimension warping equations that are planebased or cylindrical-based for panoramic images,This paper presents the new view formula that the sphere pin-hole camera model produces in the warping equation ,and the process of specific speculation.
