Correcting hyperstereopsis in a helmet-mounted vision system

Abstract

When used in conjunction with helmet mounted displays stereo camera views can provide invaluable advantages in, for example, aviation uses. One of the most common setups is to mount cameras to both sides of the pilot's helmet. However, since these cameras posses a larger disparity than the eyes distances to perceived objects are misinterpreted by the pilot. This may cause irritations, even sickness when combined with enhanced displays. Even in the best case the magnified disparity may lead to exaggerated distance estimations. In this paper simple computations are presented that can correct hyperstereopsis "on the fly". With the availability of fast computer hardware carrying out these computations in real time comes into reach. Furthermore, we sketch a series of experiments to evaluate the effectiveness of our approach.
