Diffraction Influence on the Field of View and Resolution of Three-Dimensional Integral Imaging

Abstract

Abstract-The influence of the diffraction limit on the field of view of three-dimensional integral imaging (InI) systems is estimated by calculating the resolution of the InI system along arbitrarily tilted directions. The deteriorating effects of diffraction on the resolution are quantified in this manner. Two different three-dimensional scenes are recorded by real/virtual and focused imaging modes. The recorded scenes are reconstructed at different tilted planes and the obtained results for the resolution and field of view of the system are verified. It is shown that the diffraction effects severely affect the resolution of InI in the real/virtual mode when the tilted angle of viewing is increased. It is also shown that the resolution of InI in the focused mode is more robust to the unwanted effects of diffraction even though it is much lower than the resolution of InI in the real/virtual mode.Index Terms-Diffraction, field of view, free view reconstruction, integral imaging, three dimensional imaging.

Improved multi-camera smart traffic surveillance system for resilient cities

“…On the other side, optical three-dimensional (3D) imaging techniques are able to extract the 3D image information and thus 3D objects location through the principles of geometrical and di ractive optics from the same set of multi-camera images [16][17][18]. The main advantage of using optical 3D imaging concepts in addition to image processing techniques is to make use of optical concepts when image processing fails to give accurate response.…”
