Abstract

The usual practice for stereoscopic imagery has been to capture a scene from two different viewpoints from two cameras and careful consideration needs to be given when setting up such a system. Several factors like the lens focal length, the field of view of the lens and the time of the video capture have to be precisely aligned or synchronized for both the cameras. Practically this is a cumbersome task and in this thesis, we investigate the use of a single video camera on a moving platform that eliminates the above mentioned issues and still generates the same depth as perceived by the viewer. This is achieved by presenting different video frames to the two eyes with a time-slip between them. Importance has been given to the comfort with which a viewer can perceive the 3D video. Out of the several factors that affect the viewer comfort like field of view, focal length and scene brightness, specific consideration has been given to the camera separation distance that plays the major role. Previous works show that the separation distance is a function of the focal lengths of the capturing and viewing cameras and the distances of the nearest and farthest points in the scene. Applying this to our single camera system, we obtain an optimum frame delay that ensures a good comfort for the viewer while perceiving the depth from the videos. Our system also enables the user to adjust the frame difference in case he feels uncomfortable with the optimum delay or if he feels he wants to see the scene in more depth.
