Paper Abstract

Integral Imaging is a technique that is capable of recording and replaying 3D scene in a form of a planar intensity distribution through micro-lens array. According to this technology, 3D scene information is existed in a great deal of "Element Image" under each micro-lens. A true volume spatial optical model of 3D scene can be perceived through the corresponding micro-lens array replaying. With recent progress in the theory and micro-lens manufacturing, Integral Imaging is becoming a practical and prospective 3D display technology and attracting much attention. For application, the generation of a depth map and 3D scene reconstruction from the planar recorded integral image is essential if real and/or computer generated objects are to be integrated within integral 3D images. It is also essential to enable content-based image coding and content-based interactive manipulation to be carried out within Integral images. This paper presented a method of extracting depth information and reconstructing 3D scene directly from planar recorded integral images through viewpoint image extraction, disparity analysis and depth calculation. Experiment proves that 3D scene information can be reconstructed directly from the planar recorded integral images through mathematical analysis (without using micro-lens sheet replaying). The result of the 3D reconstruction also is the foundation in further analyzing 3D spatial resolution of planar recorded integral images.
