Abstract

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
