Abstract

To obtain ideal 3D dimensional displays with crosstalk reduction

this paper researches how to arrange the elemental image and to match it with the reconstructed micro-lens array when a three dimensional scene is recorded by a camera array. The principle of integral imaging is analyzed and design parameters such as the pitch of elemental image

pitch and the focal length of the micro-lens array are studied. On the basis of the analysis

the optimum design parameters are given. Two conditions are discussed respectively when the elemental images are placed within and beyond the focal point of the micro-lenses. When the elemental images are placed at the focal plane

a virtual and real reconstructed image can be obtained simultaneously. The imaging quality is compared in above conditions. It is noted that the less crosstalk and larger depth of the focus can be seen while the elemental images are placed at the focal plane. The conclusion can provide a direction for arranging images and 3D reconstruction when the camera is used to capture a larger scene.
