Analysis of Facet-braiding Based on 3D Reconstruction of Integral Imaging
基于II三维重建的facet-braiding现象分析

Integral Imaging(II) is a technique capable of displaying threcdimensional images with continuous parallax in full natural color. Since micro-lens sheet is used in recording, only one recording is necessary in containing three-dimensional information. Facet braiding effect is an important visual phenomenon, which induces distortions and impoverishes the integral image quality. In Ref. 6 the facet braiding phenomenon was analyzed in view of single elemental image by Martinet-Cuenca. In contrast, in this paper the phenomenon was verified from the 3D reconstruction. First the traditional II system was modeled with optical software. Then the contrast experiment was drawn in the depth priority regime where the distance between the reference image plane and the reconstructed image is infinite. The facet braiding effect was not presented in our modeled optical system. The result will play an important role in viewing angle analysis, precise 3D reconstruction and spatial resolution analysis.
