Airborne stereoscopic imaging system
First Claim
1. An airborne stereoscopic imaging system comprising:
- a first aircraft having opposed first and second wings;
a first imaging sensor attached to one of said wings in a generally forward-facing field of view;
a second imaging sensor attached to the other of said wings in a generally forward-facing field of view;
said sensors being spaced from each other along a predetermined baseline distance and each sensor being movable to scan and focus at an object positioned at a distance, generally in advance of an intended flight path of said aircraft;
a stereo viewer in said aircraft for receiving imaging signals from said sensors;
means connected between said sensors and said stereo viewer for transmitting imaging signals from said sensors to said stereo viewer, such that the depth perception of a human viewer in said aircraft, viewing a display on said stereo viewer representative of the imaging signals received by said stereo viewer, is enhanced; and
further including a second aircraft, said second aircraft containing a third imaging sensor and means for radio-link transmitting a signal representative of an image on said third sensor to said first aircraft wherein the baseline distance between one of said first and second sensors and said third sensor represents said predetermined baseline distance.

Abstract
The imaging system includes widely-spaced sensors on an airborne vehicle providing a base-line distance of from about five to about 65 meters between the sensors. The sensors view an object in adjacent air space at distances of from about 0.3 to 20 kilometers. The sensors may be video cameras or radar, sonar infrared or laser transponders. Two separate images of the object are viewed by the spaced sensors and signals representing each image are transmitted to a stereo display so that a pilot/observer in the aircraft has increased depth perception of the object. In effect the interpupillary distance of the human viewer is increased from the normal 5.9-7.5 cm to from about 5 to about 65 meters resulting in depth perception of objects at a distance of from about 0.3 km to 20 km or more.

2. An airborne stereoscopic imaging system comprising:
-
an aircraft having opposed first and second wings; a first imaging sensor attached to one of said wings in a generally forward-facing field of vision; a second imaging sensor attached to the other of said wings in a generally forward-facing filed of view;
said sensors being spaced from each other along a predetermined baseline distance of from at least one meter to a distance whereat said sensors have sufficient imaging gathering ability to detect energy being reflected from a distant actual object, and each sensor being movable to scan and focus similarly at said actual object positioned at a distance, generally in advance of an intended flight path of said aircraft;a stereo viewer in said aircraft for displaying actual object images received stereoscopically from said sensors; and means connected between sensors and said stereo viewer for transmitting said actual object images from said sensors to said stereo viewer, such that the depth perception of a human viewer in said aircraft, viewing a display on said stereo viewer representative of the actual object images received by said stereo viewer, is enhanced; and including multiple imaging sensors positioned on each wing and means in said aircraft for selecting pairs of said sensors, one from each wing, for operation and transmission of images to said stereo viewer. - View Dependent Claims (3, 4)
