Abstract

The Infrared Eye is a new concept of surveillance system that mimics human eye behavior to improve detection of small or low contrast target. In search and rescue operations (SAR), a wide field of view IR camera (WFOV) of approximately 20 degrees is used for detection of target and switched to a narrow field of view (NFOV) of approximately 5 degrees for a better target identification. In current SAR system, both FOVs cannot be used concurrently on the same display. The system presented in this paper fuses on the same high-resolution display the high- sensitivity WFOV image and the high-resolution NFOV image obtained from two IR cameras. The NFOV image movement within the WFOV image is slaved to the operator's eye movement by an eye-tracking device. The operator's central vision is always looking at the high-resolution IR image of the scene captured by the NFOV camera, while his peripheral vision is filled by the enhanced sensitivity (but low-resolution) image of the WFOV camera. This paper will describe the operation principle and implementation of the display, including its interface with an eye-tracking system and the opto-mechanical system used to steer the NFOV camera.
