摘要

针对嵌入式裸眼3D设备需要同时在左右眼亚屏幕上显示立体对图像存在数据量较大和视差图像准确处理等问题，仔细研究了左右格式立体图像和液晶显示屏视频信号特点，提出一种ARM与FPGA相结合的视频信号转换系统。ARM系统作为视频播放和外设支持，为FPGA提供立体视频信号源，FPGA作为信号处理的核心，采集、缓存和转换ARM输出的视频数据，以匹配线光源背照明式裸眼3D液晶屏物理结构实现立体显示效果。实验结果表明，系统准确地完成了左右格式立体视频数据分离和融合，能够满足嵌入式裸眼3D设备对视频信号转换的要求。FPGA逻辑设计只使用内部资源实现图像数据缓存和列插值，提高了系统的可靠性并降低了成本。

Abstract

In view of the problems of large volume of data

dealing with parallax image accurately

which existed when the embedded naked-eye 3D device displaying stereo pairs image on the left and right eye sub-screen simultaneously

a video signal conversion system combined with ARM and FPGA is proposed after a careful study about the characteristic of the left and right format stereo image and LCD's video signal. As a video player and peripheral supporter

the ARM system provides the video signal source for FPGA.FPGA is used as the core of signal processing

the video data from ARM is collected

stored and converted. The new data format matches the naked-eye 3D LCD screen structure for acquiring the stereoscopic effect. Experimental results indicate that the system completes the distribution and fusion of left and right format stereo video's data correctly

and it can satisfy the embedded naked-eye 3D device for the video signal conversion. The logic design of FPGA only uses the internal resource to realize image data memory and columns interpolation

which can improve the reliability of the system and reduce the cost.
