“…More positive reception of visual information using hyperstereo displays has been identified in tasks that do not involve operation within one's personal space (defined here to be less than 20-m). For example, use of hyperstereo apparatus for viewing of distant terrain and enhanced target acquisition at 2-km [5]. Other positive perceptual acceptance of hyperstereo vision was reported in flight studies involving helicopter pilots [7].…”

“…Such tasks include the monitoring or visualization of information through existing planar display technologies [3], vehicular navigation [4], and terrain inspection at a distance [5]. The use of stereo and hyperstereo vision, (stereopsis acquired from two camera perspectives greater than normal IPD), has been proposed to circumvent specific deficits in depth perception associated with the above tasks.…”

2-D displays present significant visualization deficits and can hinder task performance when accurate perception of depth is required. Navigation of rugged terrain, scouting, and object detection at a distance all present limitations when viewed on traditional 2-D displays. The current investigation presents a novel use of stereo and hyperstereo image pairs to create a 3-D representation of the visual scene. Use of the stereo base pair provides natural depth perception for near-field viewing, while hyperstereo image pairs augment natural depth acuity for distant scenes.

The images processed by our brain represent our window into the world. For some animals this window is derived from a single eye, for others, including humans, two eyes provide stereo imagery, for others like the black widow spider several eyes are used (8 eyes), and some insects like the common housefly utilize thousands of eyes (ommatidia). Still other animals like the bat and dolphin have eyes for regular vision, but employ acoustic sonar vision for seeing when their regular eyes do not work such as in pitch black caves or turbid water. Of course, other animals have adapted to dark environments by bringing along their own lighting such as the firefly and several creatures from the depths of the ocean floor. Animal vision is truly varied and has developed over millennia in many remarkable ways. We have learned a lot about vision processes by studying these animal systems and can still learn even more.

“…9 Other authors try to use the special characteristics of hyperstereo setups to enhance the pilot's view, e.g., by enhanced depth perception. 10,11 In this paper we will develop methods to reduce or eliminate hyperstereopsis. The basic idea is to first estimate the parallaxis error from the sensor images and then correct it during image projection.…”

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.
