立体相机结构参数与立体显示效果关系研究
摘要
随着光电技术的发展人们对显示效果的要求也越来越高。立体显示是未来的发展趋势,目前立体显示已经广泛地用于在很多的领域。立体相机作为当今光电系统中的重要设备,对立体相机的结构参数与立体显示效果关系的研究是必然的。在现在的技术支持下,使用立体相机拍摄获得可用于立体显示的视差图是比较方便的途径。本文围绕立体相机的结构参数和光栅立体显示技术,介绍了光栅立体显示技术。通过对立体相机的平行式摆放结构和会聚式摆放结构两种结构分别建立相机结构拍摄物空间坐标系、显示像空间坐标系,确定二者的关系。研究了立体相机间距对拍摄获取的视差图视差值的影响。研究结果可以指导立体相机在立体拍摄时的摆放。分别对平行式和会聚式立体相机拍摄获取的视差图中存在影响显示效果的视差进行了校正,并在3D MAX中进行了仿真实验,分析了引起立体图像的畸变的原因,建立了畸变数学模型。

Study on the Relationship between Structural Parameters of Stereo Camera and Effect of Stereoscopic Display
Abstract
With the development of photovoltaic technology human’s requirements for the effect of display are also increasing. 3D display will be the trend of development in the future. In current, 3D display has been widely used in a lot of fields. As a part of the system of 3D display, stereo camera is an important equipment. Studying on the relationship between structural parameters of the stereo camera and stereoscopic display effect is inevitable. With technical supporting, using a stereo camera to obtain parallax figure, what is used for stereoscopic display is a convenient way. This paper focuses on the structural parameters of the stereo camera and raster-dimensional display technology, introduce grating 3D display. Stereo camera placement can be divided into two kinds, the stereo camera structure of parallel placement and convergent placement; those two structures were built their own camera-space coordinate, display-space coordinate, and find the relationship of those two space coordinates. Study the influences between distance of stereo camera and the parallax of parallax picture. The above can use to guide camera placement. Then separately correct the parallax what influents display of the both placements, and Simulation experiment was carried o
