Embodiment Construction

[0072] The present invention will be described in further detail below through specific control strategies in conjunction with the accompanying drawings.

[0073] The visual measurement system is responsible for calculating the relative distance and relative attitude information between the refueling cone and the refueling probe of the receiver. The scene provides image information. Through image processing, the LEDS feature points of the refueling cone are extracted, and then the corresponding feature points are matched. Finally, the position estimation algorithm is used to obtain the relative distance between the refueling cone and the receiver during the refueling docking process, which is used as the feedback of the aerial refueling controller. Measurement.

[0074] The essence of autonomous air refueling problem is the tight formation problem, that is, the control law of the receiver must make it fly to the desired fixed position, that is, the conical tube, along a feasib...

Abstract

The invention belongs to the technical field of flight control and particularly relates to an air refueling control method based on image identification. The method is characterized by including the first step of conducting vision measurement on an image to obtain pose information of a refueling cone relative to a refueled airplane, the second step of conducting calculation according to the pose information to obtain integrated error signals, and designing according to an x channel, a y channel and a z channel respectively, and the third step of obtaining control instruction information according to the integrated error signals. Through the image identification technology and the control distribution technology, the docking success rate in the refueling process in the air can be greatly improved, operation burdens of a manned airplane aviator can be reduced, and the combat radius of the airplane is expanded.

Description

technical field [0001] The invention belongs to the technical field of flight control, and in particular relates to a refueling control method based on image recognition. Background technique [0002] Autonomous aerial refueling technology is a hotspot in the field of autonomous and intelligent research of manned and unmanned aerial vehicles. This project focuses on the research of autonomous air refueling control technology, but traditional navigation and positioning methods such as GPS and inertial navigation cannot meet the measurement accuracy requirements. this problem. The method based on visual navigation is applied to autonomous aerial refueling, which forms an integrated navigation system with the original navigation system of the refueling aircraft, and as the distance between the two aircraft approaches, the proportion of visual navigation gradually increases, providing The relative position and attitude information of the refueling probe and the refueling drogu...
