Title: Study on 3D perception from pseudo-stereoscopic omnidirectional images using HMD.

 

Abstract:

Currently, virtual reality has been popular and it is easier than before to create 3D contents and to enjoy it using Head Mounted Display (HMD). An omnidirectional camera is one of the method to create a high presence virtual space. A picture or a movie in 360 degree can be taken using the camera. Unfortunately, however, it is not a 3D scene though we can see a view in any direction where we want to see. Furthermore, 2 omnidirectional cameras are needed if an accurate 3D scene is requested even if an omnidirectional camera can take an image in 360 degree. In this study, a simple method where 3D virtual space can be created using one omnidirectional camera is proposed. A right-eye image and a left-eye image are picked up from one omnidirectional image and these images are used for stereoscopic 3D technique. Of course, the right-eye and left-eye images are not correct ones. The 3D scene is a pseudo-stereoscopic view. 3D perception of the pseudo-3D view is evaluated by a questionnaire survey and an optimal condition to extract the left-eye and the right-eye images from one omnidirectional image is decided. In addition, an effect of monocular depth perception in this method, which is produced by the linear perspective, the aerial perspective and the motion parallax is investigated.
