Optimum Pitch of Volumetric Computational Reconstruction in Integral Imaging

Electronics (Switzerland)
In this paper, we propose a method for how to find the optimum pitch of volumetric computational reconstruction (VCR) in integral imaging. In conventional VCR, the pixel shifts between elemental images are quantized due to pixel-based processing. As a result, quantization errors may occur during three-dimensional (3D) reconstruction in integral imaging.

Computational volumetric reconstruction of integral imaging with improved depth resolution considering continuously non-uniform shifting pixels [PDF]

Optics and Lasers in Engineering, 2018
In this paper, we propose a new computational volumetric reconstruction technique of three-dimensional (3D) integral imaging for depth resolution enhancement by using non-uniform and integer-valued shifting pixels. In a typical integral imaging system, 3D images can be recorded and visualized using a lenslet array.

Three-dimensional volumetric object reconstruction using computational integral imaging

Optics Express, 2004
We propose a three-dimensional (3D) imaging technique that can sense a 3D scene and computationally reconstruct it as a 3D volumetric image. Sensing of the 3D scene is carried out by obtaining elemental images optically using a pickup microlens array and a detector array.

Computational Technique of Volumetric Object Reconstruction in Integral Imaging by Use of Real and Virtual Image Fields [PDF]

ETRI Journal, 2005
We propose a computational reconstruction technique in large-depth integral imaging where the elemental images have information of three-dimensional objects through real and virtual image fields. In the proposed technique, we reconstruct full volume information from the elemental images through both real and virtual image fields.
