ABSTRACT
Image matching is a key step in vision navigation and guidance. In most vision navigation systems, optical images taken by satellite cameras are set to be reference images. To ensure that the aircraft can work in any weather and time, infrared camera or Synthetic Aperture Radar (SAR) is used to take real-time images. Therefore, it is necessary to develop algorithms that can match images taken from dierent sensors with ane transformation faster and reliably.
