Abstract
This paper discusses the uses and limitations of stereo movies. Stereo movies are more complex than stereo images because of camera movement, subject movement, movie synchronization, and issues of symmetry. To capture stereo movies, I used a basic setup that featured two digital SLR cameras resting on a horizontal bar attached to a tripod. The two variations of this setup were the wide base setup in which the cameras were 36 inches apart and the narrow base setup in which the cameras were 6 inches apart. The narrow base setup was far more robust in dealing with issues of pivoting, peripherally-located objects, close-up objects, and panoramas.
Based on 15 trial movies using both wide and narrow base setups, it was determined that stereo movies are most useful for capturing object movement within a scene, recoding panoramas with ease, accompanying visual data with audio data, and using camera movement to focus on various aspects of a scene.
In addition, stereo movies are limited in that camera movements must be slow and smooth, objects must not be too close to the camera, and the setup should pivot about its center axis for panoramas.
In this project, the stereo movies were displayed in the Washington University Fossett Laboratory for Virtual Planetary Exploration (a CAVE system).
