集成成像立体显示技术性能改进研究

摘要

Integral imaging is a true 3D display technology which uses the micro-lens array to record and reconstruct the 3D scene. Researches are carried out to solve some problems of the integral imaging including black zone, narrow viewing angle, inefficiency and inaccurate depth calculation. This paper proposes a digital secondary pickup process without black zone, an integral imaging display with wide viewing angle and a rapid computer generated integral imaging. Also, we analyze the integral imaging depth range and deduce the depth calculation formulas in different display modes by using the distribution model of the Gaussian beam. These researches help to improve the performances of the integral imaging system.%集成成像是一种利用微透镜阵列来记录和再现3D空间场景的真3D显示技术.本文主要针对传统集成成像技术中存在的黑边、视角窄、记录速度慢和深度计算不准确等问题,进行了深入地分析与研究.文中建立了相应的数学模型,分别提出了消黑边的计算机二次记录和大视角的集成成像3D显示以及快速计算机集成成像方法,依据建立的高斯光束分布模型,还给出了不同显示模式下具体的集成成像深度计算方案.本研究为集成成像3D显示性能的提高提供参考.
