摘要/Abstract

摘要： 介绍一种基于瞳孔跟踪的多用户自由立体显示器，利用菲涅尔透镜形成左右眼分立照明区域。本系统采用LCD作为基本显示屏幕，通过指向式LED照明背光设计，高精度瞳孔实时定位装置对人眼位置的探测，AVR单片机的系统控制，形成实时定向跟踪人眼的立体视窗。本装置可提供±25°水平视角范围内1至3人的实时无辅助立体显示。

Abstract: This paper describes a multi-user auto-stereoscopic display based on a pupil position tracker. It employs Fresnel lens to form separate viewing regions for left and right eyes, where the corresponding left or right image is seen. LCD is used as imaging panel and LED array is used as steerable illumination backlight, enabling the viewing regions to follow the viewers’ eyes. A high-precision multi-user pupil tracker based on AdaBoost algorithm provides real-time detection of pupil locations. AVR MCU is applied for system control. As a result, within view angle of ±25° horizontally, 1-3 users may get vivid 3D images on the 3D display at the same time and move freely.

Key words: auto-stereoscopic display, Fresnel lens, LED array design, backlight control
