Abstract

We propose a new method of rendering panoramic light field within a certain range, which provides an effective way for the acquisition of virtual reality data. Different from existing panoramic light field reconstruction algorithms, we propose the concept of the ray sphere to render a panoramic light field. Using the internal and external parameters of the cameras in the acquisition system, all the light field data are uniformly expressed in the ray sphere. The constructed ray sphere enables the rendering of a panoramic light field of any view point within a 3DOF+ space, which can not be achieved with correlation methods. In addition, we design and build an acquisition system to capture real scenes to verify the effectiveness of our method. Experimental results show that our method can get panoramic light field rendering of any view point on the horizontal plane within half the radius of the acquisition system, and can effectively process the light field video data.
