【摘要】：与普通图像相比,立体图像增加了场景深度信息特征,能给观众提供更加真实的视觉感受。随着多媒体技术的迅速发展,立体视频已走进千家万户,为普通大众所熟悉和喜爱。 裸眼3D技术是无需佩戴特殊眼镜即能欣赏到立体效果的新型图像显示技术,在教育、广告、娱乐等领域具有广泛的应用。本文针对立体图像在裸眼立体显示器上的显示过程进行探讨,利用微软的MFC平台以及知名的开源视频编解码库FFmpeg实现了对立体图像的相应处理,并探讨了立体图像在手持媒体设备上的显示。主要研究内容及研究成果如下： (1)在深入理解裸眼立体显示器光学原理和静态图像数据结构及其编解码标准的基础上,利用MFC开发出立体图片处理软件。处理后的立体图片像素应与显示器光栅具有严格的对应关系,使得能够满足人眼视觉融合机制,使观察者获得深度感知。 (2)为了实现立体图像的快速融合处理,本文提出了基于矩阵变换的像素处理方法,在软件设计中采用这一方法进行了验证。在视频播放器的软件设计部分,使用FFmpeg对视频进行解码操作,SDL媒体库负责显示图像。整个软件分成三个模块：文件解析模块,解码模块,播放器显示模块。文件解析模块用于对文件格式进行分析,注册需调用的解码库；解码模块使用FFmpeg解码库将视频文件解码成流信息,为了降低开发难度,本课题只采用TS流解码库；播放器显示模块使用SDL媒体库显示解码后的视频画面。 (3)通过对Android平台系统架构的深入分析可知,基于Linux开发的FFmpeg编解码库在理论及技术上是能够移植到Android平台上的。其中移植最重要的是将FFmpeg编译成so文件,这一步骤可以在Linux环境下完成,本文着重讲述在Ubuntu环境下利用Android NDK编译成so链接库文件。 综上所述,本文主要完成了静态立体图像在裸眼立体显示器上的显示、动态立体图像在裸眼立体显示器上的播放研究,对将立体视频播放器移植到Android平台作了探讨研究。
[Abstract]:Compared with ordinary images, stereo images can provide more real visual feelings to the audience by adding depth information features of the scene. With the rapid development of multimedia technology, stereo video has entered thousands of households, familiar and loved by the general public. Naked eye 3D technology is a new image display technology which can enjoy stereoscopic effects without wearing special glasses. It has been widely used in education, advertising, entertainment and other fields. In this paper, the display process of stereo image on naked stereoscopic display is discussed, and the corresponding processing of stereo image is realized by using MFC platform of Microsoft and FFmpeg, a well-known open source video codec library. The display of stereoscopic images on handheld media devices is discussed. The main research contents and results are as follows: (1) based on the deep understanding of the optical principle of the naked eye stereoscopic display and the static image data structure and its coding and decoding standard, a stereo image processing software is developed with MFC. The processed stereo image pixels should have a strict correspondence with the display grating, which can satisfy the human visual fusion mechanism and enable the observer to obtain depth perception. (2) in order to realize the fast fusion processing of stereo images, This paper presents a pixel processing method based on matrix transformation, which is validated in software design. In the software design of video player, we use FFmpeg to decode the video and SDL library is responsible for displaying the image. The whole software is divided into three modules: file analysis module, decoding module, player display module. The file parsing module is used to analyze the file format and register the required decoding library, and the decoding module uses the FFmpeg decoding library to decode the video file into stream information. In order to reduce the difficulty of development, only TS stream decoding library is used in this subject. The player display module uses SDL-based media library to display the decoded video picture. (3) through the in-depth analysis of the Android platform system architecture, the Linux-based FFmpeg codec library can be transplanted to the Android platform theoretically and technically. The most important thing to transplant is to compile FFmpeg into so file. This step can be completed in Linux environment. This paper focuses on how to compile so link library file by using Android NDK in Ubuntu environment. To sum up, this paper mainly completes the display of static stereoscopic image on the naked stereoscopic display, and the study of the dynamic stereoscopic image playing on the naked stereoscopic display, and the research of transplanting stereo video player to Android platform.
