Abstract: | This paper investigates the impacts of stereo parameters in multiview synthesis for planar 3D display and presents a novel parameter adjustment method for reducing visual discomforts and geometric distortions. The proposed method combines the geometry of stereoscopic capturing system with the comfortable viewing rules for the human vision system in three steps. First, an identically sized representation between the virtual space and the display space is established, and the virtual camera parameters are derived based on the stereo geometry. Second, the scale factor between the physical space and the virtual space is computed based on the depth of focus theory to diminish vergence–accommodation conflicts. Last, the capturing and displaying parameters are adjusted according to the comfortable viewing zone and personal preference. Experimental results demonstrated that a reliable basis for multiview image synthesis and a more comfortable stereo perception can be achieved by applying the proposed method. |
