自由立体显示系统背光控制
Backlight System Control of Auto-stereoscopic Display
摘要
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.关键词
