Resolution-enhanced mobile three-dimensional display based on computer-generated integral imaging

摘要

In this paper, we propose the well-enhancing method for the resolution of the reconstructed image of the mobile threedimensionalintegral imaging display system. A mobile three-dimensional integral imaging display system is a valuableway to acquire the three-dimensional information of real objects and display the realistic three-dimensionalvisualizations of them on the mobile display. Here, the color and depth information are acquired by the threedimensionalscanner, and the elemental image array is generated from the acquired three-dimensional informationvirtually. However, the resolution of the elemental image array is quite low due to the low-resolution of the acquireddepth information, and it affects the final reconstructed image resolution. In order to enhance the resolution ofreconstructed images, the resolution of elemental image array should be improved by increasing the number of elementalimages, because the resolution of the reconstructed image depends on the number of elemental images. For thecomfortable observation, the interpolation process should be iterated at least twice or three times. However, if theinterpolation process is iterated more than twice, the reconstructed image is damaged, and the quality is degradedconsiderably. In order to improve the resolution of reconstructed images well, while maintaining the image quality, weapplied the additional convolutional super-resolution algorithm instead of the interpolation process. Finally, the threedimensionalvisualizations with a higher resolution and fine-quality are displayed on the mobile display.
