3D image sensing and reconstruction with time-division multiplexed computational integral imaging (CII)

Abstract

We present a method to compute high-resolution three-dimensional (3-D) images based on integral imaging. In order to overcome optical limitation on the spatial resolution of reconstructed 3-D image, we suggest performing time-division multiplexing by which a sequence of II's is captured with a slightly different location of the lenslet array. The II image sequence obtained by the detector array is processed digitally with super-resolution reconstruction algorithms to obtain a reconstructed image, appropriate to a viewing direction, which has a spatial resolution beyond the optical limitation.
