In this paper, we analyze the relationship between viewer and viewing zones of integral imaging (II) system and present a partially-overlapped viewing zone (POVZ) based integral imaging system with a super wide viewing angle. In the proposed system, the viewing angle can be wider than the viewing angle of the conventional tracking based II system. In addition, the POVZ can eliminate the flipping and time delay of the 3D scene as well. The proposed II system has a super wide viewing angle of 120° without flipping effect about twice as wide as the conventional one.

In this paper, we propose a camera array calibration method based on planar parallax for integral imaging (II) threedimensional information acquirement. The camera array is calibrated in the II pickup and the original parallaxes are aligned by the correction matrix in parallel. The proposed method increases the freedom and flexibility of the II pickup. Appropriate experiments also show the robustness of the antiinterference ability of the camera array is improved obviously.
