Dickmanns 1988d : The advantages of providing flight vehicles with a sense of vision are discussed. The use of integral spatio-temporal world models is considered to be a prerequisite for achieving real-time performance with the microprocessors currently available. Feature-based image sequence processing exploiting this approach has been tested in a real-time simulation loop, with a 10 Hz frame rate, for visual interpretation and control. Airspeed was the only quantity measured conventionally, Results for a fixed base simulation using real image sequence processing hardware in the loop are given for a final landing approach and flare at speeds around 130 kts.
