Computational Integral Imaging Reconstruction Technique with High Image Resolution

This paper presents a new method to improve the resolution of integral imaging. According to integral imaging system principle, a volume pixel of 3D scene is projected in several elemental images through micro-lens array. Contrary optic-ray pickup method is introduced in the CIIR process to reconstruct integral image by acquiring multiple pixels from various elemental images for corresponding volume pixel. To show the feasibility of proposed method, some experiments are performed, and the results are compared and discussed with those of the conventional method. The resolution of reconstruction image can be dramatically improved by the proposed method.
