Automatic recognition system for retraction and extension of aircraft landing gear

Abstract

The invention relates to an automatic recognition system for retraction and extension of an aircraft landing gear. The system belongs to outdoor day and night monitoring equipment, can assist an airport ground observer in judging whether the aircraft landing gear extends or not when an aircraft lands, and can realize all-time high-definition binocular observation of an aircraft landing area under a multi-spectrum condition. The automatic recognition system comprises a display-control computer, a pan-tilt and an image pick-up front end, wherein the image pick-up front end comprises a camera core, a windshield wiper, an image processing board and a data retransfer board. When the aircraft lands, the system can automatically track an aircraft target, automatically recognize the aircraft landing gear, and display a recognized result to the observer, so that the observer can be assisted in getting retraction and extension information of the aircraft landing gear in real time, and making a quick response to a sensitive event. The automatic recognition system is important equipment for assisting in airport security management.

Description

technical field [0001] The invention relates to the field of safe flight, in particular to an automatic identification system for retracting and retracting aircraft landing gear. Background technique [0002] Serious flight accidents will occur if the landing gear is not lowered when the aircraft lands. [0003] At present, in order to ensure that the landing gear has been put down before the plane lands, in addition to the indicating equipment on the plane, an observer is also set up next to the tower to monitor with a telescope. Once the landing gear is not put down, the observer will immediately notify the pilot. In the current method, observers tend to cause eye fatigue due to observing the aircraft through the telescope for a long time, thereby increasing mistakes. In addition, this method is easily affected by the weather, which will affect the observer's observation effect at night or under the situation of non-clear weather, and easily cause the observer to produce ...

AI Technical Summary

Problems solved by technology

The judgment features adopted by this method are greatly affected by the flight attitude of the aircraft, and the misjudgment rate is high.

In addition, this method can only determine whether the aircraft has put down the landing gear, and cannot detect the position of the landing gear and cannot give the number of landing gear
