| Description: | This conference paper was published in the Proceedings of SPIE - The International Society for Optical Engineering[ © 2017 SPIE] and the definite version is available at : http://doi.org/10.1117/12.2251360 The Journal's website is at: https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10126/1/Viewing-angle-enhancement-of-a-real-time-integral-imaging-system/10.1117/12.2251360.full?SSO=1 ; A novel method of viewing angle enhancement of a real-time integral imaging system using multi-directional projections and GPU parallel processing is proposed. The proposed system is composed of three processes: information acquisition of real objects, generation of multi-directional elemental image sets, and reconstruction of 3D images by using multidirectional projections scheme. To implement this system, depth and color (RGB) information of each object point are captured by a depth camera; then, a dynamic algorithm and GPU parallel processing are used for generating multidirectional elemental image sets to be illuminated in different directions as well as to maintain a real-time processing seed; and finally, 3D images are reconstructed by using a time-multiplexed multi-directional projection scheme through an appropriate optical setup of a projection-type integral image system. Multi-directional illuminations of elemental image sets enhance the optical ray divergence of reconstructed 3D images according to the directional projection angles. Hence, a real-time integral imaging system with enhanced viewing angle is achieved. ; Published |
