摘　　要：传统三维全息图的校正和再现方法存在运算效率低,再现影像粗糙等不足,为此提出一种新的三维全息影像失真校正和再现方法,该广泛采集所需的全息图目标场景,明确该场景的边界,在边界上自主检索到4个顶点以及4个中心的位置和相关的理想点位置,然后对图像进行投影失真校正以及非线性失真校正,并采用计算机模拟获取物体的菲涅尔物波信息,采用菲涅尔衍射积分方法获取三维全息影像的再现,最后实验结果表明,本文方法可以很好实现了三维物体的再现,并且校正和再现效果佳。Usually by optical method to realize 3 d hologram correction and reappearance,but this kind of method to operation efficiency is low,rough reproduce the image problem. According to this kind of problem,put forward a new 3 d holographic image distortion correction and representation method,it USES image processing technology,gathering the hologram the target scene,clear the border of the scenario,on the border of autonomous retrieved four vertices and the location of the center and related ideal point location,projection on the image distortion correction and nonlinear distortion correction. The computer simulation for objects of Fresnel wave information,using Fresnel diffraction integral method to obtain the images of three-dimensional hologram like. Experimental results indicate that the proposed method implements the three-dimensional objects,and good correction and reproduce the effect.
