Method and apparatus for correcting aircraft state in real time

A method and apparatus for correcting an aircraft state in real time. The method comprises: acquiring history state information of a camera unit, a current image shot by the camera unit, a history image before the current image and currently measured external information or internal information sensed by at least one sensor; forecasting matching feature points, corresponding to target feature points in the history image, in the current image according to the history state information, and calculating external information or internal information of the current camera unit according to the matching feature points; calculating a relative proportional relationship between the external information of the camera unit and the external information of the at least one sensor or a relative proportional relationship between the internal information of the camera unit and the internal information of the at least one sensor according to a position of the at least one sensor calibrated in advance relative to the camera unit; and correcting, by using the relative proportional relationship, the current state information of the camera unit obtained by estimation of the history state information. By implementing the apparatus and the method, state information of an aircraft is corrected, and errors are reduced.
