Abstract

An aerial reconnaissance camera and method provides for generating a first image of the terrain of interest with the camera pointing angle oriented or rotated about an azimuthal axis some angular amount (&thgr;1) to a first, typically forward orientation, i.e., forward of a cross-line of flight direction. An image is obtained of the ground at this orientation. Then the camera is rotated about the azimuthal axis to new angular value (&thgr;2), which will typically be aft of the cross line of flight direction. An image is generated at this value. The camera is then rotated back to the value of &thgr;1, and a second image in the forward orientation is generated. The camera is then rotated again to the value of &thgr;2 and another image in the aft orientation is generated. This process of rotating the camera about the azimuthal axis and generating images in forward and aft orientations continues over and over. Eventually, as the aircraft flies past the terrain of interest, any given location in the terrain of interest will have been imaged from two different perspectives—forward and aft. The motion of the aircraft during the interim in combination with the values of &thgr;1 and &…
