METHOD AND APPARATUS FOR CORRECTING AIRCRAFT STATE IN REAL TIME

摘要

The present invention discloses a method and apparatus for modifying an aircraft state in real time. The method comprises: obtaining historical state information of a image capturing unit, a current image shot by the image capturing unit and an historical image preceding the current image, and currently-measured external information or internal information sensed by at least one kind of sensor; predicting a matching characteristic point in the current image corresponding to a target characteristic point in the historical image according to the historical state information, and calculating, from the matching characteristic point, current external information or internal information of the image capturing unit; calculating a relative proportional relationship between the external information of the image capturing unit and the external information of said at least one kind of sensor, or between the internal information of the image capturing unit and the internal information of said at least one kind of sensor, according to a predetermined positional relationship of said at least one kind of sensor relative to the image capturing unit; and modifying current state information of the image capturing unit estimated from the historical state information, by using the relative proportional relationship. The present invention is implemented to modify state information of the aircraft and reduce a deviation.
