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.

Coarse integral volumetric imaging (CIVI) combines multiview and volumetric display solutions and presents undistorted floating 3D image by correcting distortion of volumetric image for each view. In the conventional CIVI with limited viewing angle, distortions of image planes can be approximated to be parabolic in the direction of depth, while those in horizontal and vertical directions can be ignored. When the viewing angle becomes wider, however, this approximation cannot realize presentation of undistorted image. To cope with the strong distortions, the method the authors propose calculate z-coordinate of the generated real image is in detail and depicts each pixel on the display panel of the corresponding depth. Also distortions in horizontal and vertical directions are corrected by using texture mapping. To attain precise correction in vertical, horizontal and depth directions, optical paths of light rays between the display panel and each viewpoint are calculated with an optical simulator. Color aberration can also be corrected by mapping red, green and blue textures separately based on the result of the optical simulation.
