Enhanced vision system sensitive to infrared radiation
First Claim
1. A vision system, comprising:
- a detection system configured to detect electromagnetic radiation, and to produce a detected image signal corresponding to radiation detected over a given range of wavelengths; and
a signal processor adapted to compare the detected image signal to predefined data representative of expected sensed objects, and to produce an output signal based on the predefined data when sufficient similarity is found between the detected image signal and the predefined data.

Abstract
An enhanced vision system and method for use with vision systems with an imager sensitive to infrared radiation of less than 2-microns in wavelength, to produce a first image signal. Another imager sensitive to infrared radiation at least 3-microns in wavelength may be used to produce a second image signal. Preferably, the first image signal represents sensed electric light sources, and the second image signal represents sensed background such as terrain, runways, structures, and obstacles. A signal processor combines an image signal representing locally maximum values of the first image signal with the second image signal to create a displayed image.
