Advanced mobile three-dimensional display based on computer-generated integral imaging

Abstract

In this paper, we focused on the improvement of reconstructed image quality of the mobile three-dimensional display using the computer-generated integral imaging. The three-dimensional scanning method is applied instead of capturing the depth image in the acquisition step, and much more accurate three-dimensional view information (parallax and depth) can be acquired compared with the previous mobile three-dimensional integral imaging display, and the proposed system can reconstruct clearer three-dimensional visualizations of real-world objects. Here, the three-dimensional scanner acquires the three-dimensional parallax and depth information of the real-world object by the user. Then, the entire acquired data is organized and the three-dimensional the virtual model is generated based on the acquired data, and the EIA is generated from the virtual three-dimensional model. Additionally, in order to enhance the resolution of the elemental image array, an intermediate-view elemental image generation method is applied. Here, five intermediateview elemental images are generated between each four-original neighboring elemental image according to the pixel information, at least, the resolution of the generated elemental image array is enhanced almost four times than original. When the three-dimensional visualizations of real objects are reconstructed from the elemental image array with enhanced resolution, the quality can be improved quite comparing with the previous mobile three-dimensional imaging system. The proposed method is verified by the real experiment.
