The 3D computer graphics image, created from DEM, is
used as reference image for the rectification process.
Rectification is done by matching the skyline edges of the
digital camera landscape image and the reference image [4].
The skyline edge image of the 3D computer graphics is called
reference edge image, and the skyline edge image of the
digital camera image is called original edge image. There are
some advantages in matching skyline. In this method, any
ground control targets do not need to be setup, but only the
skyline is needed for the rectification. The whole skyline is not
necessary for the matching. Even though some parts of the
skyline is covered by cloud or smoke, it is possible to obtain
image matching. Here, this method is called skyline matching.
As stated in the later part of this paper, this matching process
can be applied to thermography image as well.
