摘要

提出了一种会聚式集成成像法用于增大其3D观看视角。该成像方法包括会聚式集成成像3D拍摄和会聚式集成成像3D显示两个过程。在3D拍摄过程中

各透镜元的3D拍摄视角不再是中心对称的

而是根据透镜元在微透镜阵列中所在的位置来设置其3D拍摄视角

每个透镜元的拍摄视角分别由上、下、左、右拍摄视角组成。在3D显示过程中

设置的参数与3D拍摄时的参数完全相同

图像元节距大于透镜元节距

使得每个透镜元的观看视角互相会聚

从而增大了集成成像的3D观看视角。模拟实验显示:会聚式集成成像的3D视角是常规成像方式的近3.4倍

且消除了串扰。实验结果验证了理论推导的正确性。

Abstract

A toed-in integral imaging method is proposed to increase the three-dimensional(3D) viewing angle of integral imaging. The method contains a toed-in integral imaging 3D pickup process and a toed-in integral imaging 3D display process. In the toed-in 3D pickup process

the shooting angle of each micro-lens is not centrosymmetric anymore

and it is set based on the position of each micro-lens in the micro-lens array. The shooting angle of each micro-lens contains upper

lower

left and right shooting angles. In the toed-in 3D display process

the parameters for the 3D display are the same as the parameters in 3D pickup process and the pitch of the elemental image is larger than that of the micro-lens

by which the viewing angle of each micro-lens is converged together

and the 3D viewing angle is increased. In the simulating experiments

the 3D viewing angle of toed-in integral imaging is about 3.4 times of conventional one

in addition the crosstalk is eliminated as well. The experimental results verify the correctness of the theoretical analysis.
