TLDR
In this article, a new Ray-Space acquisition system using two parabolic mirrors is presented. But only static scenes can be captured by this method, and only static objects can be detected by this approach.Abstract:
In this paper, we introduce a new Ray-Space acquisition system that we developed. The Ray-Space method records the
position and direction of rays that are transmitted in the space as ray data. The composition of arbitrary viewpoint images
using the Ray-Space method enables the generation of realistic arbitrary viewpoint picture. However, acquisition of a
dense Ray-Space is necessary to apply the Ray-Space method. The conventional method of acquiring the ray data uses a
camera array. This method enables capturing a dynamic scene. To acquire a dense Ray-Space by this method, however,
interpolation is necessary. There is another common method for ray data acquisition, which uses a rotating stage. This
method enables capturing images without requiring interpolation. However, only static scenes can be captured by this
method. Therefore, we developed a new Ray-Space acquisition system. This system uses two parabolic mirrors. Incident
rays that are parallel to the axis of a parabolic mirror gather at the focus of the parabolic mirror. Hence, rays that come out
of an object that is placed at the focus of the lower parabolic mirror gather at the focus of the upper parabolic mirror. Then,
the real image of the object is generated at the focus of the upper parabolic mirror, and a rotating aslope mirror scans rays
at the focus of the upper parabolic mirror. Finally, the image from the aslope mirror is captured by a camera. By using this
system, we were able to acquire an all-around image of an object.read more
