Stereo depth-fused 3D rendering for stacked stereo displays

Abstract

We propose a rendering method that enables the perception of 3D images at precise positions independent of the interocular distance of the observer by combining stacked stereo display and depth-fused 3D (DFD) display and confirm its effectiveness through evaluation experiments. The depth range that can be expressed in stereo displays causes discomfort in observers because of the discrepancy between vergence and accommodation. However, the depth perceived differs depending on the interocular distance of the observer, resulting in discontinuity of the 3D image. Therefore, we propose a rendering method for stacked stereo displays that is independent of the observer's interocular distance using DFD display.
