Virtual Multiple-Perspective Display Using Pyramidal or Conical Showcase

Abstract

We implement a virtual display system using pyramidal or conical showcase. For image acquisition, a real object is placed inside the showcase made of mirror coated surfaces and a multiple-perspective image (or video) is captured by a bird-view camera. The captured image (or video) is processed to remove outliers in the background and compensate distortion. For virtual display, the processed image (or video) is shown on a flat screen, and the transparent surfaces of the showcase reflect the contents on the screen so that a hologram seems to appear inside the virtual showcase. The proposed system can be used to display any expensive, fragile, sensitive, or unique objects while the genuine objects are stored in a secured or remote location. Some possible applications of the proposed virtual showcase include digital museum, online exhibition, jewelry show and commercial display.
