【摘要】： 立體顯示技術是一項多學科的綜合技術,涉及電子、光學、計算機、攝影等領域的研究成果。其信息源的獲取除景物的二維信息攝入外,還需探測各像素的深度信息,并以三維的形式顯示出來,而現(xiàn)階段的顯示設備基本上只能顯示二維平面信息或經透視處理的仿三維信息(如3D max、Solid Works、CAD等),給予觀察者暗示的立體感覺。為了使顯示的場景和物體具有真實的深度感覺,人們采用各種方法進行了嘗試。特別是近十幾年來,立體顯示技術取得了超乎尋常的快速發(fā)展,并在教育、醫(yī)學、建筑、軍事、商業(yè)廣告、工業(yè)產品設計等領域受到高度關注,應用前景廣泛。深入研究和發(fā)展立體顯示技術將會給人們的生產和生活帶來顯著的變革和深遠的影響。其中的自由立體顯示模式更有呵能大量取代現(xiàn)有的平面顯示機制。 本文研究工作主要集中在光學原理探索、樣機的研制、立體圖像序列的獲取與合成算法和對立體顯示效果的量化評價這幾個方面。取得的研究成果和創(chuàng)新點表現(xiàn)在: 1、在研究多種立體顯示方法的光學原理并對其進行評價比較的基礎上,提出了基于柱狀透鏡與DMD投影技術的自由立體顯示系統(tǒng)解決方案。采用柱狀透鏡作為主要分光器件,在DMD投影屏幕前形成區(qū)域的視障以造成左右眼視差,獲得立體效果。 2、研究了相應的立體圖像序列的獲取及合成算法。重點研究了雙目視差、顯示器像素和柱狀透鏡線數(shù)的對應關系.柱狀透鏡發(fā)散角度等因素對市體顯示效果的影響,給出了理論公式。提出了一種基于傾斜柱狀透鏡的立體序列圖合成算法。 3、在完成了系統(tǒng)樣機之后,提出了一種使用照度計測量立體顯示屏近場區(qū)域亮度分布的方法,對立體顯示器的立體效果進行量化的評價,并采用這種方法對基于DMD投影的立體顯示系統(tǒng)的兩種不同的圖像序列合成算法進行了測試和比較,給出了具體的測量值和結果。 論文最后對全文進行了總結,指出了研究工作尚待改進之處。對今后的的研究方向提出了建議。
[Abstract]:Stereoscopic display technology is a multi-disciplinary technology, which involves the research achievements in the fields of electronics, optics, computer, photography and so on. In addition to the two-dimensional information intake of the scene, it is also necessary to detect the depth information of each pixel and display it in three-dimensional form. At the present stage, the display equipment can only display two-dimensional plane information or three-dimensional information (such as 3D maxmaxid works CAD, etc.), which can give the observer a hint of stereoscopic sensation. In order to make the scene and object have real depth sense, people have tried various methods. Especially in the past ten years, stereoscopic display technology has made extraordinary rapid development, and has been highly concerned in the fields of education, medicine, architecture, military affairs, commercial advertising, industrial product design and so on. Further research and development of stereoscopic display technology will bring significant changes and profound effects to people's production and life. One of the free stereoscopic display mode can replace the existing plane display mechanism. This paper focuses on the exploration of optical principle, the development of prototype, the acquisition and synthesis algorithm of stereo image sequence and the quantitative evaluation of stereoscopic display effect. The research results and innovations are as follows: 1. On the basis of studying the optical principle of various stereoscopic display methods and evaluating and comparing them, Based on cylindrical lens and DMD projection technology, the solution of free stereoscopic display system is presented. The columnar lens is used as the main optical splitter to form the visual barrier in front of the DMD projection screen to cause the parallax of the left and right eyes and to obtain the stereoscopic effect. 2. The corresponding algorithms for the acquisition and synthesis of stereo image sequences are studied. The relationship among binocular parallax, display pixels and the number of cylindrical lens lines is studied. The influence of the divergence angle of cylindrical lens on the display effect of the market body is given, and the theoretical formula is given. This paper presents an algorithm of stereo sequence diagram synthesis based on tilted cylindrical lens. 3. After completing the prototype of the system, a method of measuring the luminance distribution in the near field region of the stereoscopic display screen by using illuminometer is presented. The stereoscopic effect of stereoscopic display is quantitatively evaluated, and two different image sequence synthesis algorithms based on DMD projection are tested and compared, and the specific measurement values and results are given. Finally, the thesis summarizes the whole paper and points out that the research work needs to be improved. Suggestions for the future research direction are put forward.
