Aerial Infrared Imagery
ABSTRACT
agery is imagery that shows heat. It is often in the form of a grayscale picture whose shades of gray indicate the differences
ivity of objects in the image. Typically, objects in the image that look lighter are warmer and those that look darker are
cts are the warmest in the images. Black objects are the coolest. Any object with a temperature above absolute zero ( 0
Celsius) emits infrared radiation. An infrared picture only shows objects which emit infrared wavelengths in the 3000-5000
in visible light wavelengths of 400 to 700 nanometers are detected, but only because they also emit heat. An example of
eet light that can be seen in the IR imagery. The image may be modified in a number of ways to enhance its value to the end
alse-color image or adjusting the brightness and contrast of a grayscale image. The digital images are captured directly to
on a CD-ROM.
