迎着2006年的春光,全国科技大会在京隆重召开。这次科技盛会,恰逢“十一五”规划实施的开局之年,它预示着我国科技大发展的又一个春天来到了! 21世纪是人类充满希望的世纪,同时也是科学技术激烈竞争的世纪。在这次大会上,党和国家的领导人胡锦涛指出,“这次会议的主要任务是:分析形势,统一思想,总结经验,明确任务,部署实施《国家中长期科学和技术发
Facing the spring of 2006, the National Science and Technology Conference was grandly held in Beijing. This science and technology event coincides with the first year of the implementation of the “Eleventh Five-year Plan”, which indicates that another spring has come for the great development of science and technology in our country. The 21st century is a century full of hope for mankind and a century of fierce competition in science and technology . At the conference, Hu Jintao, leader of the party and the state, pointed out: “The main tasks of this conference are: analyzing the situation, unifying our thinking, summing up experiences, clearly defining tasks, and deploying and implementing the” Medium and Long-Term Scientific and Technological Development

传统方法是建立从光场到显示面的映射计算生成元素图像,但会存在很多冗余映射。针对这一问题,提出沿光路逆向迭代的算法,建立从元素图像显示面到重建光场的单射,使元素图像中的每个像素只对应唯一的光场像素,这可以提高像素的匹配精度,消除深度阶跃处的空洞。所提算法的核心是以元素图像显示面每一点为始点,经过透镜的光心作射线,通过迭代搜索求出射线与光场曲面距离观察者最近的交点,并作为元素图像的匹配点。所提算法的时
