A System for Capturing, Rendering and Multiplexing Images on Multi-view Autostereoscopic Display

Abstract

Current trends in digital display technology show a marked interest towards 3D displays, which allow three dimensional images to be conveyed to viewers. Among various 3D display techniques, auto stereoscopic display appears to be promising due to the use of optical trickery at the display, allowing glass-free viewing. However, the cost of generating and transmitting the auto stereoscopic images is usually quite high due to the huge amount of data. Hence, it is challenging to acquire artifact-free 3D images in real-time. This paper presents a system to generate and display high-resolution auto stereoscopic images at full HD resolution, i.e., 1920*1080*24. We show that the video-plus-depth data representation enables a scalable system architecture and efficient data transition. The proposed GPU accelerated depth image-based rendering (DIBR) algorithm and multiplexing algorithm are able to synthesize auto stereoscopic images in real-time. The synthesized images are then displayed on the auto stereoscopic screen that is mounted on a conventional LCD monitor. We demonstrate our system to both indoor activities and natural scenes.
