摘要

针对三维集成成像与显示技术中光学阵列式物体三维信息获取的要求

提出了一种确定最佳记录距离的新方法来减少相邻成像单元间的干扰和三维再现过程中的串扰现象。通过分析大小不同的物体在不同记录距离处的物点成像率和像点利用率

确定了合理的记录距离。分析结果表明

对于特定的集成成像系统

该新方法确定的最佳记录距离处的物点成像率和像点利用率的乘积比传统方法均有较大提高

最大可以提高34倍。另外

通过光学实验实现了完整且细节丰富的三维图像再现

进一步验证了这一方法的正确性。该方法同时适用于透镜阵列和照相机阵列的三维信息获取。

Abstract

By taking optical acquiring 3D objects with a lens array for an example

a method to obtain the optimal pick-up distance was proposed to reduce the elemental image overlap and the crosstalk in reconstructed three-dimensional images for 3D integral imaging and display technology. By analyzing the effective imaging rates of object points and the image point utilization of objects with various sizes at different pick-up distances

the optimal pick-up distance was achieved. Compared with conventional methods for a specific integral imaging system

the product of the effective imaging rates of object points and image point utilization has increased at the optimal pick-up distance and the maximum one can increased by 34 times. Optical experimental results show that the reconstructed images has full 3D information and wealth detail

which verifies the feasibility of the proposed method. Moreover

the method is suitable for both the lens array and the camera array to acquire 3D information.
