【摘要】：随着科学技术的进步,人们开始追求更高的生活品质,渐渐地,对于佩戴助视设备观看3D电影这一日常休闲活动开始感到不满,期望可以有更加随意自由的虚拟现实体验。目前裸眼立体显示技术越来越成熟,应用越来越广泛,但是多数情况下,都是使用在专门的设备上,作为普通的观察者,能够亲身接触裸眼立体显示的机会并不多,而且大多时候,观察者并不懂得如何操作裸眼立体显示系统,这影响了裸眼立体显示技术的推广。本文提出了利用交互技术,来帮助观察者了解熟悉裸眼立体显示,并获得更好的虚拟现实体验的方法。本文以实现基于裸眼立体显示系统的交互技术为目标,深入研究了裸眼立体显示技术,并为达成提供更好的虚拟现实体验这一目的,进行了交互技术的学习、研究、设计工作,以及对于所采用的交互技术在裸眼立体显示系统中深度信息设置方面的研究工作。在交互技术研究方面,人机交互的方法有很多,本文旨在为观察者降低与裸眼立体显示系统交流的难度以及辅助提供更好的显示及互动效果,以便推广裸眼立体显示技术。所以,基于2D+D的柱状光栅裸眼立体液晶显示器的系统特性提出了通过采用交互式界面来实现观察者与裸眼立体显示系统的交互的方法,为观察者提供了一种相较于OSG系统复杂的漫游操作更简便的操作方式,同时允许观察者自由的调整视角和模型以及与模型进行简单的互动。在界面制作上,使用CEGUI工具库,通过CEED软件对界面进行可视化编辑,通过imageset对控件进行编辑,通过layout来设置控件,免除在OSG中对界面布局的代码工作。在界面深度信息讨论的问题上,本文通过对人体产生立体感的各种因素进行分析,提出了界面作为一个平面图像,会从主观角度上影响观察者的立体感受这一论点。经过建模分析,得出了最优的界面深度值,将交互式界面的深度设置在无穷远处,即Dui = 0,有效的增强了观察者最终获得的立体感同时也确保了交互界面在裸眼立体显示系统中的显示精度。最终实验结果表明,通过本论文中的所述的方法,可以在2D+D的柱状光栅裸眼立体液晶显示器中获得较好裸眼立体显示效果,观察者也可以顺利的与虚拟场景和模型进行简单交互,有效地提高了观察者的虚拟现实体验感受。从本文的实现结果来看,最终展示效果和交互效果均可接受,但都有一定的局限性。
[Abstract]:With the development of science and technology, people began to pursue higher quality of life. Gradually, they began to feel dissatisfied with the daily leisure activity of wearing visual aids to watch 3D movies, and expected to have a more casual and free virtual reality experience. At present, the naked eye stereoscopic display technology is more and more mature and widely used, but in most cases, it is used in special equipment, as an ordinary observer, there are few opportunities to contact the naked eye stereoscopic display in person. And most of the time, observers do not know how to operate naked stereoscopic display system, which affects the promotion of naked stereoscopic display technology. In this paper, an interactive technique is proposed to help the observer understand the naked eye stereoscopic display and gain a better virtual reality experience. In order to realize the interactive technology based on the naked eye stereoscopic display system, this paper deeply studies the naked eye stereoscopic display technology, and in order to provide a better virtual reality experience, we study, research and design the interactive technology. And the research work on the depth information setting in the naked eye stereoscopic display system by using the interactive technology. In the research of interactive technology, there are many methods of human-computer interaction. The purpose of this paper is to reduce the difficulty of communication with the naked eye stereoscopic display system and to provide better display and interactive effect, so as to promote the naked eye stereoscopic display technology. Therefore, based on 2D D, the characteristics of columnar raster stereoscopic liquid crystal display (LCD) with bare eye are discussed. The interactive interface is used to realize the interaction between the observer and the naked eye stereoscopic display system. It provides a more convenient way for the observer to operate than the complex roaming operation in OSG system, and allows the observer to adjust the visual angle and model freely and interact with the model easily. In interface making, CEGUI tool library is used to visually edit interface through CEED software, control is edited by imageset, and control is set by layout, which eliminates the code work of interface layout in OSG. On the discussion of the depth information of the interface, this paper analyzes the various factors of the human body's three-dimensional feeling, and puts forward the argument that the interface, as a plane image, will influence the three-dimensional perception of the observer from the subjective angle. Through modeling and analysis, the optimal interface depth is obtained, and the depth of the interactive interface is set at infinity. That is, Dui = 0 effectively enhances the stereoscopic perception that the observer finally obtains and also ensures the display accuracy of the interaction interface in the naked eye stereoscopic display system. Finally, the experimental results show that the method in this paper can get a better effect in 2D D cylindrical raster stereoscopic liquid crystal display. The observer can also interact with the virtual scene and model smoothly, which effectively improves the virtual reality experience of the observer. From the implementation results of this paper, the final display effect and interactive effect are acceptable, but they all have some limitations.
