【摘要】：立體顯示作為現(xiàn)代顯示的新技術(shù),能夠再現(xiàn)場(chǎng)景的三維信息,使顯示畫面更加逼真,更具有沖擊力。傳統(tǒng)的立體顯示需要觀看者佩戴偏振光眼鏡、互補(bǔ)色眼鏡等輔助工具,將人的雙眼完全占有,在許多場(chǎng)合非常不適用。裸眼立體顯示摒棄了輔助工具對(duì)人眼的束縛,用戶觀看是完全自由、不受限制的。LED顯示屏作為現(xiàn)代信息展示的重要載體,被廣泛應(yīng)用于商場(chǎng)、展會(huì)、機(jī)場(chǎng)等場(chǎng)所。因此,研究基于LED顯示屏的裸眼立體顯示為L(zhǎng)ED產(chǎn)業(yè)提供了新的發(fā)展途徑,將具有廣闊的市場(chǎng)前景。 本文在研究裸眼立體顯示技術(shù)的基礎(chǔ)上,綜合考慮LED顯示屏自身的顯示方式與應(yīng)用環(huán)境,通過(guò)對(duì)比研究柱面透鏡立體顯示以及狹縫光柵立體顯示的各自特點(diǎn),研究了適用于戶外LED顯示屏的裸眼立體顯示方法——狹縫光柵裸眼LED立體顯示法。鑒于雙視點(diǎn)裸眼立體顯示對(duì)可視區(qū)域的限制,研究采用多視點(diǎn)技術(shù),實(shí)現(xiàn)了四視點(diǎn)狹縫光柵裸眼LED立體顯示。針對(duì)豎直狹縫光柵立體顯示存在明顯的莫爾條紋會(huì)對(duì)人們觀看立體顯示的生理感受產(chǎn)生影響,通過(guò)采用斜置狹縫光柵來(lái)實(shí)現(xiàn)裸眼LED立體顯示以提高觀看舒適度。在上述研究基礎(chǔ)上,設(shè)計(jì)了斜置狹縫光柵多視點(diǎn)裸眼LED立體顯示屏,搭建了裸眼LED立體顯示平臺(tái),對(duì)斜置狹縫光柵多視點(diǎn)立體顯示進(jìn)行了實(shí)驗(yàn)。結(jié)果表明,采用斜置狹縫光柵四視點(diǎn)裸眼LED立體顯示已經(jīng)產(chǎn)生了明顯的立體顯示效果。 針對(duì)斜置狹縫光柵四視點(diǎn)裸眼LED立體顯示,研究了圖像合成的方法,設(shè)計(jì)了圖像合成軟件。通過(guò)研究立體顯示的評(píng)價(jià)方法對(duì)斜置狹縫光柵四視點(diǎn)裸眼LED立體顯示效果進(jìn)行了主觀和客觀評(píng)價(jià)。
[Abstract]:Stereoscopic display, as a new technology of modern display, can reproduce the 3D information of the scene, make the display more realistic and have more impact. Traditional stereoscopic display requires the viewer to wear polarized glasses. Complementary color glasses and other auxiliary tools, the human eyes are completely occupied, in many cases very inapplicable. The naked eye stereoscopic display abandoned the aid tools to the human eye, the user is completely free to watch. Unrestricted. Led display screen as an important carrier of modern information display, is widely used in shopping malls, exhibitions, airports and other places. The study of naked stereoscopic display based on LED screen provides a new way for the development of LED industry and will have a broad market prospect. Based on the research of naked eye stereoscopic display technology, this paper comprehensively considers the display mode and application environment of LED display screen itself. The characteristics of cylindrical lens stereoscopic display and slit grating stereoscopic display are compared. The naked eye stereoscopic display method, slit grating naked eye LED stereoscopic display method, which is suitable for outdoor LED display screen, is studied in this paper. In view of the limitation of double-view naked eye stereoscopic display to the visual region, the multi-view technology is adopted. A four-view slit grating naked eye LED stereoscopic display is realized. The obvious moire fringes in vertical slit grating stereoscopic display will have an impact on the physiological perception of people viewing stereoscopic display. The oblique slit grating is used to realize the naked eye LED stereoscopic display to improve the viewing comfort. On the basis of the above research, a multi-view open-eye LED stereoscopic display screen with oblique slit grating is designed. An open-eye LED stereoscopic display platform is built, and the multi-view stereoscopic display of slanted slit grating is tested. LED stereoscopic display with oblique slit grating with four points of view has already produced obvious stereoscopic display effect. For the oblique slit grating four-point naked eye LED stereoscopic display, the method of image synthesis is studied. The image synthesis software is designed and the evaluation method of stereoscopic display is studied to evaluate the effect of oblique slit grating four-view naked eye LED stereo display subjectively and objectively.
