【摘要】：圖像顯示器是人類接受外部信息的重要手段之一。顯示技術的根本目的在于真實的復原原始圖像中的物體信息,給觀眾帶來身臨其境的真切現(xiàn)場感,從這個角度來看,3D顯示技術成為顯示技術的主流具有其必然性,而裸眼3D顯示技術發(fā)展是未來的必然趨勢。 本文首先對超高清信號處理進行研究,選擇了4K2K作為系統(tǒng)的顯示分辨率,介紹了信號傳輸技術,分析了V-by-One技術的優(yōu)勢,并針對本系統(tǒng)設計了FRC和Up-scaler信號處理流程,完成了超高清顯示效果的分析評價；其次對多視點裸眼3D顯示技術進行研究,介紹了深度提取算法,DIBR算法和圖像映射,完成了多視點裸眼3D顯示效果測試；最后對2D/3D顯示切換技術進行研究,分析了基于視差光柵和微柱透鏡裸眼3D顯示技術方案,并對本設計系統(tǒng)的2D/3D顯示模式實際進行測試。 論文的工作成果及主要技術創(chuàng)新點體現(xiàn)在如下： (1)系統(tǒng)為多視點裸視3D顯示系統(tǒng),支持對單視角2D視頻和雙視角的2D視頻處理運算,并且由于采用4K2K顯示屏,在多視點裸眼3D顯示時還是可以保證高清分辨率顯示水平。 (2)系統(tǒng)不僅支持4K2K源生信號輸入并且無損顯示,還支持非4K2K的普通視頻圖像信號做Up-scaler到4K2K顯示,同時還支持對兩種信號的FRC運算,另外系統(tǒng)還采用了新的視頻傳送技術V-by-One; (3)系統(tǒng)支持2D顯示模式和3D顯示模式切換,在2D模式下可以達到4K2K超高清顯示,在3D模式下為9視點的裸眼3D顯示,可以在不同的應用需求下切換不同的顯示模式； 另外,還針對多視點裸眼3D系統(tǒng)的具體應用,設計了一套基于高度集成化的SoC電視處理芯片,高性能的FPGA芯片和并行高效的FRC芯片構建的多視點裸眼3D電視解決方案,并完成相應的硬件電路及電路模塊的開發(fā)。
[Abstract]:Image display is one of the important means for human to receive external information. The basic purpose of the display technology is to restore the object information in the original image, and bring the audience a real sense of the scene. From this point of view, it is inevitable that 3D display technology has become the mainstream of the display technology. The development of naked-eye 3D display technology is an inevitable trend in the future. In this paper, the UHD signal processing is studied, 4K2K is selected as the display resolution of the system, the signal transmission technology is introduced, the advantages of the V-by-One technology are analyzed, and the FRC and Up-scaler signal processing flow is designed for the system. The analysis and evaluation of the effect of UHD display are completed. Secondly, the technology of multi-view naked eye 3D display is studied. The depth extraction algorithm, DIBR algorithm and image mapping are introduced, and the effect test of multi-view naked eye 3D display is completed. Finally, the 2D/3D display switching technology is studied, the 3D display scheme based on parallax grating and microcylindrical lens is analyzed, and the 2D/3D display mode of this design system is tested. The main achievements and technical innovations of the thesis are as follows: (1) the system is a multi-view naked 3D display system, which supports 2D video processing operation of single view 2D video and dual view, and because of the use of 4K2K display screen, In multi-view naked eye 3 D display, high-definition resolution level can be guaranteed. (2) the system not only supports 4K2K source signal input and lossless display, but also supports Up-scaler to 4K2K display of non-4K2K video image signal, and also supports FRC operation of two kinds of signals. In addition, the system also adopts a new video transmission technology V-by-One; (3) the system supports the switching of 2D display mode and 3D display mode, which can achieve 4K2K ultra-high definition display in 2D mode, and naked eye 3D display with 9 views in 3D mode, and can switch different display modes under different application requirements; In addition, aiming at the concrete application of multi-view naked eye 3D system, a set of multi-view naked eye 3D TV solution based on highly integrated SoC TV processing chip, high performance FPGA chip and parallel and efficient FRC chip is designed. And complete the development of the corresponding hardware circuit and circuit module.
