Epipolar Navigation
an image appears to change as viewed from a moving point of view. The
human eye/brain system does this to a limited degree with little thought
or conscious effort. Robot vision systems can do it with extreme precision.
To illustrate epipolar navigation, imagine a robotic aircraft (drone)
flying over the ocean. The only land beneath the drone is a small island
(see the illustration).The robot controller has,on its hard drive,an excellent
map that shows the location, size, and exact shape of this island. For
instrumentation, the drone has only a computer, a good video camera,
and sophisticated programming. The drone can navigate its way by
