Integral Imaging With Digital Reconstruction Based On Computer

The display system of traditional integral imaging could generate a 3D image by optics reconstruction system using optics device, the effect of imaging was influenced by lens and LCD. Based on optics reconstruction theory, this article designs and realizes computer-based digital reconstruction of integral imaging.This article analyzes the basic principles of integral imaging and proposes a non-periodicity pixel extraction method to eliminate the overlapping of periodicity method. Then according to optics ray principle, one volumetric pixel can be extracted from multiple elemental images to improve the viewing resolution of reconstructed 3D images. At last, we make an experiment to test this method.This design regards elemental images picked up by CCD and microlens array as experimental object. According to analysis result of theory, we use MATLAB to extract pixels and reconstruct images so that we can get the 3D images with multiple improving resolution.
