Abstract :
A Dual Swath BuckEye EO imaging system has been developed and flown for emergency response to natural disasters. The Dual-Swath BuckEye EO sensor head is comprised of a pair of nadir pointing 39 Megapixel or 60.5 Megapixel CCD cameras for simultaneously acquiring twin adjacent aerial digital images to double imaging swathwidth for a panoramic field of view (14, 200 × 5, 400 pixels or 18, 800 × 6, 700 pixels) and obtaining wide ground-track coverage. The Dual-Swath BuckEye EO imaging system fully integrates a sensor head, embedded computers, and a precision GPS/IMU device into a 25lb package. The system is implemented with fast processing capabilities for direct aerial image geo-reference, orthorectification, and fast image mosaic. High resolution fast corridor mapping samples are presented. These include 11 cm resolution and one (1) mile wide corridor mosaics over the flooded Upper Mississippi river in Iowa and a 4 cm resolution single-pass photomap for a tornado damaged corridor in New Hampshire.
