作为基于DTV/ HDTV的二维(2D)显示之后的下一代视频显示技术,三维(3D)多视点立体显示已成为国际上的研究热点之一。为建立多视点立体显示系统,阐述了相关的关键技术,包括:光场表示模型和光场获取系统、高效的与现行视频标准兼容的多视点编码和传输方法、解码端任意位置视点的高效绘制方法、3D显示技术以及多视点自由立体显示。针对上述关键技术,分析了当前国际上的发展趋势及存在的问题,同时提出了一种基于交互式自由立体显示的3D视频处理系统的解决方案。
As a next-generation video display technology based on DTV / HDTV two-dimensional (2D) display, three-dimensional (3D) multi-view stereoscopic display has become one of the hot topics in the world. To establish a multi-view stereo display system, the related key technologies are described, including: light field representation model and light field acquisition system, multi-view coding and transmission method with high efficiency and compatibility with the current video standards, efficient drawing method of viewpoints at any position in the decoder , 3D display technology and multi-view free stereoscopic display. In view of the above key technologies, the current international development trends and existing problems are analyzed, and a solution to the 3D video processing system based on the interactive free stereoscopic display is also proposed.
