【摘要】：立体显示作为现代显示的新技术,能够再现场景的三维信息,使显示画面更加逼真,更具有冲击力。传统的立体显示需要观看者佩戴偏振光眼镜、互补色眼镜等辅助工具,将人的双眼完全占有,在许多场合非常不适用。裸眼立体显示摒弃了辅助工具对人眼的束缚,用户观看是完全自由、不受限制的。LED显示屏作为现代信息展示的重要载体,被广泛应用于商场、展会、机场等场所。因此,研究基于LED显示屏的裸眼立体显示为LED产业提供了新的发展途径,将具有广阔的市场前景。本文在研究裸眼立体显示技术的基础上,综合考虑LED显示屏自身的显示方式与应用环境,通过对比研究柱面透镜立体显示以及狭缝光栅立体显示的各自特点,研究了适用于户外LED显示屏的裸眼立体显示方法——狭缝光栅裸眼LED立体显示法。鉴于双视点裸眼立体显示对可视区域的限制,研究采用多视点技术,实现了四视点狭缝光栅裸眼LED立体显示。针对竖直狭缝光栅立体显示存在明显的莫尔条纹会对人们观看立体显示的生理感受产生影响,通过采用斜置狭缝光栅来实现裸眼LED立体显示以提高观看舒适度。在上述研究基础上,设计了斜置狭缝光栅多视点裸眼LED立体显示屏,搭建了裸眼LED立体显示平台,对斜置狭缝光栅多视点立体显示进行了实验。结果表明,采用斜置狭缝光栅四视点裸眼LED立体显示已经产生了明显的立体显示效果。针对斜置狭缝光栅四视点裸眼LED立体显示,研究了图像合成的方法,设计了图像合成软件。通过研究立体显示的评价方法对斜置狭缝光栅四视点裸眼LED立体显示效果进行了主观和客观评价。
[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.
