摘要

基于微透镜阵列多视角成像特点

利用几何光学原理

提出一种对物体进行三维数字成像的重构算法。利用这种算法

对CCD相机捕获到的基元图像阵列进行重构。与传统的利用光学系统对物体进行重构的方法相比

该算法不再受到重构过程中遇到的杂光以及衍射效应等因素的影响

具有实时性好、清晰度高的优点。搭建了基于微透镜阵列的三维数字成像系统实验平台

利用此算法对实验中获得的骰子基元图像阵列进行重构

成功地重构出原始物体的三维立体图像

在理论上和实验上证明了这种重构算法的有效性和可行性

并对实验中影响成像质量的因素进行了分析。

Abstract

A new reconstruction algorithm was proposed based on multi-perspective imaging characteristics of a microlens array and geometrical optical principles. By proposed algorithm

an original object was reconstructed with the elemental image array captured by a CCD camera. In compasison with traditional method using optical systems

this algorithm was not affected by the stray light and diffraction effect in the process of reconstruction

and has advantages of real-time and sharp quality. An experimental platform based on a three-dimensional digital imaging system with a microlens array was setup to reconstruct the elemental image array of a die captured in experiment

a volumetrically original image was reconstructed through this algorithm successfully. It is proved that the algorithm is feasible and valid both theoretically and experimentally.Finally

several factors affecting the imaging quality in the experiment are analyzed.
