一种基于空间散射元点阵的真三维显示方法

摘要

阐述了一种真三维显示方法,方法能够显示对象的物理深度,从而真实地表达第三维.方法基于空间散射元点阵,通过特定算法,生成要显示的对象的平行投影图像.然后,利用透镜折射投影仪光线来获得平行的投射光线,点亮点阵中对应的散射元.在已有方法基础上进行了改进,采用确定性的点阵分布,研究了点阵分布的寻优,并提出利用深度编码产生投影图的方法,最后进行了计算机模拟验证.改进后的方法,在保证了良好的可见度基础上简化了原始方法中的生成投影图的算法,提高了显示效率.%A true-3D display method is introduced, which can display an object' s physical depth so that to express the third dimension in real.This method is based on scatterer space lattice and generates parallel projection image of the object to be displayed by specified algorithm.After that, the lights from lens refraction projector are used to catch parallel projecting light and to light corresponding scatterers in the lattice.In this paper, the authors made improvement on the basis of existing method.We adopted deterministic lattice distribution and studied the lattice distribution optimisation, then proposed a method to generate projection images by using depth encoding, and finally made simulation validation on computer.The improved method simplifies the algorithm of projection image generation in primitive method while ensuring good visibility, and raises the efficiency of display.
