 note = {A method to estimate the position and attitude of a helicopter with respect to the landing site from a image sequence of a heliport is presented. The method use the circle of the heliport marking as the visual cue. The projection of the circle on the successive image taken by on board camera will change, therefore a Kalman filter can be build for the recursive estimation. The method needs to know just there is a circle ; The size of the circle is not necessary. The result of the experiment on the synthetic data shows the method works well under several assumotions., 6, KJ00001512029, 論文, Article},
