The Naked-eye Stereoscopic Display Technology And Applications

As a new type of image-display technology, the naked-eye stereoscopic display enables viewers to have a unprecedentedly vivid visual experience without wearing3D glasses. Based on the theory of parallax, the Naked-eye stereoscopic display products can be widely applied in fields such as education, exhibition, entertainment, multimedia,movable termination,and are expected to have a huge market demand.The industrialization of naked-eye stereoscopic display technology involves many parts like camera technique.content manufacture,display content,etc. This paper focuses on researching how to achieve a naked-eye stereoscopic display effect in a two-dimensional medium, how to apply naked-eye stereoscopic display technology into product manufacture, and what is the internal principle of stereo-pair image of the naked-eye stereoscopic display products,and the main content is listed as follows:(1) A comparative research on key contents such as the optical principle of the naked-eye stereoscopic display technology and the measuring method of the characteristic parameters. The stereoscopic image should accord with the stereoscopic visual fusion mechanism of human eyes,and stereo-pair image with depth cue should be obtained via parallax and cross of optical axises.(2) A discussion of the industrialization plan of the naked-eye stereoscopic display technology. To meet the performance requirement of average entertainment and multimedia equipments, a specially-developed naked-eye stereoscopic display screen is used to design a series of naked-eye stereoscopic display products.including computer monitor, portable multimedia device.communication device,building advertisement machine.And based on those products, some patents have been applied for.(3) Two-dimensional images in a plane surface can not achieve the stereoscopic visual effect demanded in man-machine conversation of naked-eye stereoscopic display products. In order to livingly present the visual effect of naked-eye stereoscopic display technology in paper material and web page,there is a need to discuss the manufacture of the showing pictures. A method to make showing pictures of stereoscopic display effect by use of photoshop is introduced in this paper. The layer-overlapping drawing technique in photoshop can contribute to a vivid stereoscopic visual effect,thus is adopted in promoting products and introducing achievement.(4) Content manufacture is a bottleneck that constrain the popularization of stereoscopic display technology.During the process of imitating binocular viewing mechanism,the optical parameters of camera lens determine key factors such as parallax and depth of field.According to the relationship between depth of field,parallax and lens matching.some experiments have been designed in this research project,using separate double lens and commercial stereoscopic cameras to shoot pictures of targets. In this way,factors having influence on binocular parallax and depth of field is studied by extracting and analyzing the featuring points of image and analysis of MATLAB data.In sum. this paper has completed part of the design program of industrializing the naked-eye stereoscopic display technology.completed the systemic composition research, completed research on making the showing picture of naked-eye stereoscopic display effect,completed the experimental research on relationship between parallax,depth of field and double CCD parameters. The research project has achieved its goal and some of the achievements have been applied into practical use.
