Fast Generation of Perspective Display from Spherical Bubble

Abstract

In the research of robot vision, perspective display often needs to be generated from omnidirectional images. In this paper, we represent 360-degree immersive panorama by SCVT(Spherical Centroidal Voronoi Tessellation) image, referred to spherical bubble, and propose a method of quickly generating the perspective display from spherical bubble according to users' view direction and zoom-in/out operation. This process is done by employing the adjacent cues between neighboring cells and the pyramid data structure of spherical bubble. The experimental results are also presented to show the effectiveness of the proposed method.
