User interactive high-resolution multi-view display system using a three-dimensional head-tracking camera

Multiview display is a popular method to deliver three-dimensional (3D) images by generating a perspective directional view. However, there are some limitations such as a low resolution, lack of motion parallax, and a narrow viewing angle. In this paper, we propose a method to implement a multi-view display system that provides a 3D image in high resolution. The original setup is composed of a stereoscopic 3D display panel and a head tracking camera. The directional view image of a 3D object is captured by a camera array and shown on a stereoscopic 3D display. A user interface is designed to control the hardware. An Intel RealSense sr300 camera is used to track the observer's viewing angle. The images are captured rotationally through a movable camera array in a 30-degree span. There are 71 and 3 views in the horizontal and vertical direction, respectively. The directional view information is displayed according to the observer's viewing direction as well as the head position. The observer can realize a high-resolution 3D image with smooth motion parallax. Most importantly, the proposed system interactively displays the exact view direction according to the user's viewing angle which feels more natural to the observer.
