Zusammenfassung: | The invention discloses an aircraft positioning method based on vision and air pressure information fusion, which comprises three steps of initialization setting and data acquisition, and pose resolving and state updating at adjacent moments, and real-time positioning of an aircraft can be obtained through cyclic recursion. According to the positioning method, the air pressure information and the visual navigation information are intelligently fused, so that measurement of a vertical position can be obtained through the air pressure information, and the problem of scale factors existing in a monocular vision technology is solved; on the other hand, different flight stages of the current aircraft can be reflected through the change of the air pressure information, different air pressure and visual information fusion methods are adopted to obtain real-time position estimation of the aircraft, and positioning is more accurate and rapid. According to the method, the reliability and credibility of aircraft positio |
