Problems solved by technology

In the existing method, the LED light is used as the detection feature of the visual measurement of the refueling drogue, and the spatial pose of the refueling drogue is solved by using the correspondence between the spatial point and the image point. The feature extraction is difficult, the pose calculation algorithm is complex and the accuracy is low, especially It is the measurement of the spatial attitude of the refueling drogue. Due to the symmetry of the circle in the image, the ambiguity of the attitude calculation has not been resolved, leaving a safety hazard for the autonomous aerial refueling process.

Abstract

The invention discloses a drogue spatial attitude measuring method and system, and relates to the technical field of air refuelling. By combining a red ring reflective membrane ellipse fitting result with a blue ring reflective membrane ellipse fitting result and using an intense light source in an assisted manner, strong features of vision of a drogue are formed, so that the vision measurement precision of the drogue is high, by red and blue features, the problem of ambiguity of attitude calculation of the drogue is solved effectively, and therefore, air refueling docking success rate is increased.

Description

technical field [0001] The invention relates to the technical field of aerial refueling, in particular to a method and system for measuring the space attitude of an aerial refueling drogue.
