摘要：

虚拟弯曲透镜阵列已成为提高三维集成成像质量的有效手段．针对典型虚拟弯曲透镜阵列的集成成像系统，依据集成成像记录与重构原理，利用ABCD矩阵光学理论，推导了三维物体与三维集成图像的映射位置关系模型，实现了虚拟弯曲透镜阵列集成图像的计算生成与重构|引入成像取样率模型，定量分析了记录过程单元图像取样率与不同深度重构集成图像质量的关系．最后，利用相关度图像度量因子比较了虚拟弯曲透镜阵列和传统平面透镜阵列的集成图像质量，证明了虚拟弯曲透镜阵列在提高三维集成成像质量方面的优越性．

Abstract:

The virtually curved lens-array has become an effective way to improve the image quality of Integral Imaging (II). Based on the principle of the pick-up and reconstruction processes of a typical Virtually Curved Integral Imaging (VCII) system, the optical ABCD matrix theory is utilized to derive the mapping relationship between the three-dimensional object and 3D integral image, and the VCII computational reconstructed image is realized. Then a theoretical model of the elemental image sampling rate is introduced to analyze the relation between the sampling rate and the reconstructed image quality at various depths. Finally, by using the correlation image metric factor, a comparison between the VCII and the conventional II reconstructed image quality is performed, which confirms the advantage of the virtually curved lens-array in improving the integral image quality.

Key words: integral imaging, virtually curved lens-array, image quality, sampling rate, correlation
