Abstract
Conventional 3D movie systems with the special glasses such as polarized glasses provide us touchable spatial images. However, these 3D imaging systems require the observer to wear the glasses. Our research group would like to realize the glasses-less 3D imaging system to construct an interactive spatial imaging environment. The authors have researched the 3D displays and applications. We have ever proposed 3D displays using the slit as a parallax barrier, the lenticular screen and the holographic optical elements(HOEs) for displaying active image<sup>1,2,3</sup>. We developed a prototype field-lens 3D display with a tracking system. This system consists of the user's position detection system and the spatial imaging system. In this paper, we describe the method of 3D measuring using a single camera for tracking users' positions and a 3D display system using a field-lens which can display full screen high resolution views. This 3D display can solve the traditional defect that the horizontal resolution of each image is divided in half.
