【摘要】： 圖像顯示器是人類接受外部信息的重要手段之一。而立體顯示則能再現(xiàn)場景的三維信息,提供場景的更為全面、詳實的信息,在醫(yī)學(xué)、軍事、廣告藝術(shù)以及立體電視等領(lǐng)域有著廣泛的應(yīng)用前景。傳統(tǒng)的立體圖像顯示需要佩帶諸如偏振眼鏡、互補色眼鏡或者液晶眼鏡之類的輔助工具,因此將人眼完全占有,人的眼睛除了觀看屏幕之外,做其他與屏幕無關(guān)的工作都十分不便。因此,佩帶眼鏡的立體顯示技術(shù)(包括立體頭盔),盡管其立體顯示效果特別優(yōu)良,但在許多場合是不適用的�；诖�,我們研究了基于柱透鏡陣列的裸眼立體顯示技術(shù),即依據(jù)柱透鏡陣列對光線的折射作用,結(jié)合數(shù)字圖像處理技術(shù),將包含立體信息的屏幕圖像分離成左、右兩個視像,分別提供給用戶的雙眼,經(jīng)過大腦合成,使平面圖像轉(zhuǎn)化為具有縱深感的立體圖像。裸眼立體顯示技術(shù)無需佩帶眼鏡,用戶在觀看立體顯示器的時候眼睛不受限制,是完全自由的,因此,可以同時進(jìn)行除了觀看顯示器以外的其他工作,從而具有更大的靈活性和實用性。 本文首先介紹立體視覺基礎(chǔ)知識及相關(guān)理論。裸眼立體顯示技術(shù)基于人類的雙眼“視差”,即人眼睛的功能決定了立體視覺的形成。立體顯示技術(shù)是結(jié)合了人本身參與的系統(tǒng),顯示器件其實只是完成立體視覺的部分功能,而人眼的生理功能完成剩余的工作。所以在第二章使用一定的篇幅來介紹人眼的立體視覺機制。 本文的第三章從裸眼立體顯示器的共性特點出發(fā),結(jié)合立體顯示的幾何模型,分析了基于柱透鏡陣列的使圖像分離的幾何關(guān)系,在此基礎(chǔ)上,計算了光線分離的布局特征。在亞屏幕分區(qū)和視圖分離物理特性研究的基礎(chǔ)上,進(jìn)一步計算了獨立視區(qū)的位置。在光學(xué)原理研究的結(jié)論指導(dǎo)下,初步研制出原理樣機。 本文的第四章研究了裸眼立體顯示器適用的圖像格式及其變換方法,編寫了靜態(tài)立體對轉(zhuǎn)換軟件,以典型的立體對復(fù)合圖像表示變換的效果,實驗證實了設(shè)計方法的正確性。 在上述各點中,有兩點是本文的創(chuàng)新點: 1.把裸眼立體顯示器的物理本質(zhì)概括為分離和會聚兩個過程;提出“亞屏幕”分區(qū)和虛擬屏幕的概念,這兩個概念和“獨立視區(qū)”解釋了裸眼立體顯示器的物理特性,具有指導(dǎo)意義; 2.提出和使用“動態(tài)裝配法”用于立體顯示液晶屏的裝配工藝,不需要花費巨大的特種設(shè)備,以低廉的價格制備了試驗設(shè)備,思路和方法具備借鑒意義。
[Abstract]:Image display is one of the important means for human to receive external information. Stereoscopic display can reproduce the three-dimensional information of the scene and provide more comprehensive and detailed information of the scene. It has a broad application prospect in the fields of medicine, military affairs, advertising art and stereoscopic television. Traditional stereoscopic images need to wear auxiliary tools such as polarizing glasses, complementary colored glasses or liquid crystal glasses, so the human eye is fully occupied, and the human eye, in addition to looking at the screen, It is inconvenient to do other work that is not related to the screen. Therefore, the stereoscopic display technology with glasses (including stereoscopic helmet) is not suitable for many occasions, although its stereoscopic display effect is particularly good. Based on this, we study the naked eye stereoscopic display technology based on cylindrical lens array, that is, according to the refraction effect of cylindrical lens array to light, combined with digital image processing technology, the screen image containing stereo information is separated into left and right images. Through brain synthesis, the plane image is transformed into a stereoscopic image with a sense of depth. The naked eye stereoscopic display technology does not need to wear glasses, the user's eyes are not restricted when viewing the stereoscopic display, and they are completely free, so they can do other work besides viewing the display at the same time. So it has more flexibility and practicability. This paper first introduces the basic knowledge of stereo vision and related theories. The technology of naked eye stereoscopic display is based on the parallax of human eyes, that is, the function of human eyes determines the formation of stereoscopic vision. Stereoscopic display technology is a combination of human participation in the system, display devices in fact only complete a part of the functions of stereo vision, while the human eye physiological function to complete the rest of the work. So in the second chapter, we use a certain space to introduce the stereo vision mechanism of human eyes. In the third chapter, based on the general characteristics of naked eye stereoscopic display and the geometric model of stereoscopic display, the geometric relationship of image separation based on cylindrical lens array is analyzed. On this basis, the layout characteristics of light separation are calculated. Based on the study of the physical properties of sub-screen partition and view separation, the position of independent view area is further calculated. Under the guidance of the conclusion of the optical principle research, the prototype of the principle is developed preliminarily. In the fourth chapter of this paper, the image format and its transformation method are studied, and the static stereo pair conversion software is written. The effect of the transformation is represented by typical stereoscopic images. The experimental results show that the design method is correct. Among the above points, there are two innovations in this paper: 1. The physical nature of the naked eye stereoscopic display is summarized as two processes of separation and convergence, and the concepts of "sub-screen" partition and virtual screen are proposed, which explain the physical properties of the naked eye stereoscopic display. Have guiding significance; 2. This paper puts forward and uses "dynamic assembly method" for the assembly process of stereoscopic display LCD screen. It does not need huge special equipment, and the test equipment is prepared at a low price. The ideas and methods have reference significance.
