x86结构下的多视点裸眼立体显示实时合成并行算法研究

摘要

目前的柱栅式裸眼立体显示技术已经能够在 UHD 模式下具有良好的2D 显示性能，但是随着分辨率的提高，立体显示图像的合成所需要处理的数据量急剧增加。为此，我们在 x86架构运行环境下，提出了一种采用 SIMD 指令集来实现显示图像实时合成的算法。实验表明，相比于通用算法，该算法可大幅减少运算时间，速度提高了1个数量级以上。有效满足柱栅式立体显示系统图像的实时合成，具有一定的工程实际意义。%Ultra High-Definition auto-stereoscopic display technology with lenticular works well in the 2D model now,but the data for stereo synthesis increases sharply when the resolution is higher.In this paper,we propose a fast parallel algorithm using Single Instruction Multiple Data to solve real-time synthesis in the x86 architecture operating environment.The results show that it substantially increases synthesis rate compared to the general algorithm,faster than an order of magnitude.It effec-tively meets the need of real-time synthesis in Multi-view Auto-stereoscopic display technology and has certain practical significance.
