Zusammenfassung: | The invention discloses a method for estimating aircraft speed based on a single-scene high-resolution optical remote sensing image. According to the method, since the principle of the algorithm for measuring motion parameters does not utilize imaging time intervals of different sensors, the method is widely applied to high-resolution optical remote sensing satellites adopting push-broom linear array sensor to collect images, in particular to satellites only adopting one kind of wave band sensor, such as WorldView-1 and the like; in addition, the algorithm solves the motion direction of an aircraft in a mode of direction vector quantity, and does not require the actual flight direction of the aircraft consistent with or opposite to the motion direction of a satellite; the algorithm does not require an exact spatial position of a characteristic point on the aircraft, only needs to know relative positions among characteristic points, that is, by only knowing imaging time intervals and geometrical parameters of |
