Active integral imaging system based on multiple structured light method.

In this paper, we simplify the equipments for integral imaging (II) pickup and implement an active II system based on multiple structured light (MSL) method. In the active II system, the complete three-dimensional (3D) shape of the 3D scene can be reconstructed, and the tunable parallaxes can be generated without occlusions. Therefore, the high-quality 3D images can be displayed efficiently by the II. We also use the Compute Unified Device Architecture implementing the processing algorithms in graphics processing unit. The experimental results demonstrate the effectiveness of the MSL method for the II pickup and the acceleration for the elemental image array generation. Especially, the proposed method is suitable for the real scene with high precision.

Nonunified integral imaging elemental image array generation method based on selective pixel sampling algorithm.

We propose a method based on the selective pixel sampling algorithm to generate a nonunified integral imaging (II) elemental image array (EIA) with reduced moiré patterns at a low rendering cost and high three-dimensional (3D) resolution. In the proposed method, the redundant 3D information is captured for the nonunified pixel arrangement of elemental images, and the moiré patterns are constrained by the constraint equations. The nonunified EIA's corresponding information is mapped from the obtained 3D information based on the selective pixel sampling algorithm. Appropriate experiments are carried out, and the experimental results show that the proposed method can increase the 3D display quality of the reconstructed 3D images in the II display and reduce rendering costs markedly in the generation of ultra-high-definition EIA.

Partially-overlapped viewing zone based integral imaging system with super wide viewing angle.

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.
