Effects of Extended Camera Baseline and Image Magnification on Target Detection Time and Target Recognition with a Stereoscopic TV System.

Abstract : Accomplishments of the first year of a two-year investigation of remote presence with a stereoscopic TV display are summarized. A dual-channel video recording and playback system was constructed, consisting of a synchronized pair of optical video disk recorders under computer control, used to record stereoscopic still video frame-pairs in the field and play them back in a controlled laboratory environment for visual performance data collection. Three experiments were conducted to assess the independent effects of camera interaxial separation, image magnification, and their simultaneous interaction on target detection and recognition. The results of these experiments suggested that both image magnification and increases in camera interaxial separation are useful strategies for enhancing visual performance. The interaction of these two factors did not disrupt performance. Recommendations are made for the conduct of subsequent studies and for the design of stereo TV displays for terrestrial reconnaissance applications.
