Correction Techniques for Depth Errors with Stereo Three-Dimensional Graphic Displays

Abstract

(Maximum 200 words) Three-dimensional (3-D), "real-world" pictorial displays that incorporate "true" depth cues via stereopsis techniques have proved effective for displaying complex information in a natural way to enhance situational awareness and to improve pilot/vehicle performance. In such displays, the display designer must map the depths in the real world to the depths available with the stereo display system. However, empirical data have shown that the human subject does not perceive the information at exactly the depth at which it is mathematically placed. Head movements can also seriously distort the depth information that is embedded in stereo 3-D displays because the transformations used in mapping the visual scene to the depth-viewing volume (DVV) depend intrinsically on the viewer location. The goal of this research has been to provide two correction techniques; the first technique corrects the original visual scene to the DDV mapping based on human perception errors, and..
