Realization of precise depth perception with coarse integral volumetric imaging

In this paper realization of precise depth perception using coarse integral volumetric imaging (CIVI) is discussed. CIVI is a 3D display technology that combines multiview and volumetric solutions by introducing multilayered structure to integral imaging. Since CIVI generates real images optically, optical distortion can cause distortion of 3D space to be presented. To attain presentation of undistorted 3D space with CIVI, the authors simulate the optics of CIVI and propose an algorithm to show undistorted 3D space by compensating the optical distortion on the software basis. The authors also carry out psychophysical experiments to verify that vergence-accommdation conflict is reduced and depth perception of the viewer is improved by combining multiview and volumetric technologies.
